Software-As-A-Service SaaS | Glossary

Software-as-a-Service (SaaS) is the modern standard for delivering software functionality. This cloud-based delivery model has fundamentally redefined how organisations consume and pay for business applications, shifting control and responsibility from the end-user to the cloud service provider.¹ Understanding the architecture, financial implications, and strategic risks associated with SaaS is now crucial for any technology or finance leader.

What is Software-as-a-Service (SaaS)?

Software-as-a-Service definition in plain English refers to a method of delivering applications over the internet on a subscription basis.¹ ² Instead of purchasing a license and installing software on a local device or server, users access the application through a web browser or API.³

The provider manages the entire underlying technology stack, including the infrastructure, operating system, application code, security patches, and maintenance.¹ This arrangement offers customers a cost-effective and highly convenient way to access powerful business tools without the complexities inherent in traditional software deployment.¹

SaaS meaning in a commercial context suggests a relationship where the customer rents access to the software functionality, much like paying rent for an apartment rather than buying the whole building.² This active provision and maintenance by the vendor is what defines the ‘as-a-Service’ component, differentiating it from a simple product sale.²

The Relevance to Digital Transformation

Software-as-a-Service is central to modern digital transformation efforts across all industries.⁴ It enables organisations to deploy new features and systemic improvements to their software with high frequency through continuous release cycles.⁵

This ability to innovate quickly leads to increased efficiency and an improved user experience.⁶ When executed strategically, these digital transformation initiatives are projected to unlock significant value, potentially adding as much as $1.25 trillion in additional market capitalisation for Fortune 500 companies alone.⁵

The widespread adoption of cloud-based software accelerated dramatically following 2020.⁴ Microsoft CEO Satya Nadella noted that digital transformation efforts expected to take a decade happened within just a few years.⁴ SaaS platforms provided the necessary agility to meet these unprecedented demands for remote work and rapid scaling.

Current Market Scale and Trajectory

The global market for Software-as-a-Service solutions demonstrates powerful momentum. Worldwide spending is expected to reach $295 billion by 2025, driven by an annual growth rate of 19.4%.⁷ Other projections indicate the market could hit $300 billion by 2025.⁸

This substantial growth confirms that SaaS has become the primary, default method by which applications are delivered to companies worldwide.⁹ The US remains the largest SaaS market, with revenues expected to exceed $225 billion by 2025.⁷

The transition to SaaS delivery signifies a fundamental shift in business ownership and liability. By delegating complex infrastructure management to specialised cloud providers, companies are better able to focus their internal resources on core business outcomes and unique competitive differentiators.¹⁰

The Evolution of SaaS: From CDs to the Cloud

The concept of sharing centralised computing resources predates the internet by many decades. The history of Software-as-a-Service tracks closely with the evolution of centralised computing models and commercial internet availability.

Early Foundations: Time-Sharing and Service Bureaus

In the 1960s, the first conceptual predecessors to SaaS emerged with time-sharing systems.¹¹ ¹² These systems allowed multiple users to share access to a single, powerful mainframe computer.¹¹ This laid the initial technological groundwork for shared, centralised access.

Service bureaus, which provided technology-based services like payroll processing, were also operating during this period.¹³ These early models demonstrated the viability of consuming specific business functions as a service rather than executing them entirely in-house.

The Application Service Provider Era (Late 1990s)

The direct ancestor of modern SaaS was the Application Service Provider (ASP) model, which gained traction in the late 1990s.¹³ ¹⁴ ASPs offered a hosted, one-to-many business model, delivering business-critical applications over a network.¹⁴

While ASPs introduced the idea of hosted applications, they were often highly vertical-focused and lacked the scale and technological robustness of modern cloud infrastructure.¹⁴ The ASP model eventually transitioned into the far more scalable SaaS model we know today.¹³

The Birth of Modern SaaS and Cloud Infrastructure

The founding of Salesforce in 1999 is widely regarded as the start of modern Software-as-a-Service.¹¹ ¹² Salesforce revolutionised the software distribution model by offering its Customer Relationship Management (CRM) solution entirely over the web via a recurring monthly subscription.¹¹ This model shifted the financial focus from a one-time product sale to an ongoing service relationship.¹⁵

The subsequent launch of Amazon Web Services (AWS) in 2006 provided the essential, scalable cloud-based software infrastructure.¹¹ ¹⁶ AWS allowed SaaS providers to scale their operations globally without needing massive upfront investment in physical hardware, significantly boosting SaaS adoption and affordability.¹¹

Mass Adoption in the 2010s

The growth of SaaS exploded in the 2010s, becoming the norm due to several converging factors. The proliferation of affordable, high-speed broadband and mobile devices ensured that ubiquitous access to cloud services became technically feasible for both consumers and businesses.¹⁶

The success of consumer-facing SaaS examples, such as Gmail and Dropbox, demonstrated the simplicity and accessibility of the model.¹¹ ¹⁷ By 2009, global monthly data traffic was measured in exabytes—billions of gigabytes—confirming that the volume of data moving across the internet had reached an inflection point, solidifying the cloud as the standard way of computing.¹⁶

The evolution confirms that the ultimate distinction between ASPs and modern SaaS was driven less by the underlying technology and more by the SaaS business model itself.⁹ This model—defined by continuous service and predictable, recurring revenue—is a key driver of the high valuations seen in the technology sector.⁹

Software-As-A-Service SaaS | Glossary

How SaaS Works (Without the Tech Jargon)

Software-as-a-Service operates on two core technical principles: centralised cloud hosting and multi-tenancy. These principles enable the inherent accessibility and efficiency characteristic of the SaaS delivery model.

Centralised Hosting and Browser Access

In the SaaS model, the vendor hosts the application on its own or a third-party cloud infrastructure.³ This means the software application, all associated data, and the necessary underlying computing resources reside entirely on remote, cloud-based servers.¹

Users access the software on demand via a simple internet connection, usually through a standard web browser.¹⁸ This delivery method eliminates the need for manual installations, downloads, or local maintenance on individual employee devices.¹⁸

The Architecture: Multi-Tenancy

Multi-tenancy is the defining architectural feature of most large-scale SaaS applications.¹ ¹⁹ It enables a single instance of the software application and its supporting infrastructure to serve multiple, distinct customers, known as tenants.¹⁷ ¹⁹

The architecture operates like an apartment building.¹⁷ All tenants share the same physical infrastructure, such as the plumbing and foundation, but each maintains their own private, secure apartment or data space.¹⁷

This shared resource model is critical for SaaS architecture efficiency.²⁰ By pooling computing resources and storage capacity across numerous tenants, the provider reduces its operating costs.¹⁷ This resource optimisation allows the vendor to offer the service more cost-effectively and enables massive scale to be achieved rapidly.²⁰

The ‘Noisy Neighbour’ Consideration

While multi-tenancy is highly efficient, it introduces a specific technical challenge known as the “noisy neighbour” problem.¹⁹ Since all tenants share the underlying compute resources and sometimes a common database, the unusually high workload of one tenant can sometimes impact the performance, or increase the latency, experienced by other tenants.¹⁹

Addressing this requires robust application-level monitoring by the vendor.¹⁹ For enterprises demanding consistent, high-performance service, this is a crucial trade-off against the cost benefits of the shared multi-tenant SaaS environment.

Subscription and Licensing Models

Unlike traditional software which uses a perpetual license paid for upfront, SaaS relies on a recurring subscription model, providing continuous access.¹⁵ ²¹ This structure ensures continuous revenue for the provider and aligns costs with usage for the customer.

Several common subscription and SaaS pricing models are widely used ¹⁵:

  • Tiered Fixed Fee: This model offers customers several plans—often labelled Bronze, Silver, or Gold—each with a fixed monthly price but differing levels of features, functionality, and capacity.²¹ This accommodates different needs, from small businesses to large enterprises.
  • Pay-per-Seat: Common in collaboration and productivity tools, this approach charges a fee based on the number of individual active users or “seats” provisioned within the customer’s organisation.¹⁵
  • Freemium: Customers can use a basic version of the software without charge.¹⁵ Fees are only incurred when users upgrade to premium features or require expanded functionality.
  • Pay-as-You-Go (Usage-Based): Customers are charged based on their actual consumption metrics, such as the volume of data processed, the number of API calls made, or storage utilisation.¹⁵

Security, Updates, and Maintenance

In the SaaS paradigm, the customer is relieved of responsibility for software upkeep.¹ The vendor handles all hardware management, operating system updates, application patching, and critical security updates automatically.²⁰ ²² Customers always operate on the latest, most secure version of the application.²⁰

Despite resource sharing, security measures such as advanced data encryption, firewalls, multi-factor authentication, and robust data backups ensure that each tenant’s data is isolated, protected, and private.¹⁷ ²⁰

SaaS vs On-Premises vs PaaS vs IaaS

Software-as-a-Service is the pinnacle of abstraction within the broader field of cloud computing, fitting into a hierarchy that includes Platform as a Service (PaaS) and Infrastructure as a Service (IaaS).²³ These models are differentiated by the specific division of operational responsibility between the customer and the provider.

On-Premises Software: Full Control, Full Liability

The traditional, on-premises model serves as the baseline, representing total customer control and total liability.²³ The organisation must purchase, install, manage, and maintain every layer of the computing stack, from the physical networking and hardware to the application itself.³ ²⁴ This demands significant upfront capital expenditure (CAPEX) and a large, skilled internal IT team.²³

Infrastructure as a Service (IaaS)

IaaS is the most hands-on cloud service model.²⁴ It provides foundational IT resources, such as compute, networking, and storage, delivered over the internet.²³ The vendor manages the physical hardware and virtualisation layers.

However, the customer remains responsible for managing the operating system, middleware, runtime environments, and the applications themselves.²⁴ IaaS offers high flexibility for organisations requiring custom configurations and deep control over their application environment.²⁴

Platform as a Service (PaaS)

PaaS sits one layer higher than IaaS. It provides a complete cloud environment for developers, offering tools necessary to build, run, and manage applications.²⁴ The provider manages the operating systems, middleware, and underlying infrastructure.

This structure allows developers to focus entirely on writing and deploying application code and managing data, significantly accelerating deployment times.²³ PaaS is critical for organisations that prioritise rapid development without the burden of server management.

Software as a Service (SaaS)

SaaS represents the maximum level of managed service.²³ The provider manages all aspects of the stack—from the network hardware up to the application code.¹ The customer’s responsibility is limited to managing user access, authentication, and the organization’s data.²⁴

This complete abstraction allows for immediate use and removes the need for in-house IT expertise for installation, maintenance, or upgrades, making it the preferred option for standardised business functions.²²

Cloud Service Management Responsibility

Understanding the relative responsibilities of each cloud model is essential for strategic IT decisions.

Benefits of SaaS for Businesses

The widespread adoption of Software-as-a-Service is driven by significant strategic and operational benefits, particularly concerning financial flexibility and deployment speed.

Software-As-A-Service SaaS | Glossary

The Financial Advantage: CAPEX to OPEX Shift

One of the most compelling SaaS benefits for business is the fundamental shift in IT spending from Capital Expenditure (CAPEX) to Operating Expenditure (OPEX).¹⁰ CAPEX involves large, infrequent purchases of fixed assets, such as servers and perpetual software licenses.²⁵

Conversely, SaaS operates on a subscription or pay-as-you-go basis, classifying costs as OPEX.²⁵ This transformation eliminates the need for massive upfront fees, making sophisticated software immediately accessible.²⁷

Predictable Budgeting and Tax Treatment

OPEX costs provide superior financial agility.¹⁰ Since SaaS is subscription-based, IT costs become predictable, manageable monthly or annual fees, which directly align spending with current resource usage.¹⁰

Furthermore, OPEX costs are typically deductible in the same tax year they are incurred.²⁵ In contrast, CAPEX requires the cost of fixed assets to be depreciated over several years, slowing the recognition of the investment.²⁵ This financial model is one of the key SaaS cost savings mechanisms.

Rapid Deployment and Accessibility

SaaS solutions enable immediate business activation.²⁷ Since the application is already installed and configured on the provider’s cloud infrastructure, set-up time is minimal.²⁷ This rapid deployment significantly reduces the time-to-value compared to traditional on-premises software, which can require lengthy installation and configuration projects.

The benefits of cloud computing through SaaS also include ubiquitous access.²⁷ Employees can access the application from any location using an internet connection and a standard device, fostering remote work and collaboration capabilities.²⁷

Reduced Operational Burden and Evergreen Software

By taking responsibility for the entire infrastructure, the SaaS provider drastically reduces the operational burden on the customer’s internal IT team.²⁴ Maintenance, security patching, and disaster recovery are managed externally.²⁷ This frees up IT professionals to focus on strategic initiatives unique to the business.²⁸

SaaS also ensures continuous innovation.⁶ Features and performance improvements are delivered automatically through continuous release cycles.⁶ This “evergreen” approach means customers never face the expensive, disruptive manual upgrades common with legacy software.²⁷

Challenges and Risks of SaaS

Despite the significant advantages, the adoption of the SaaS model introduces several strategic and operational risks that organisations must address, particularly as usage scales.

Software-As-A-Service SaaS | Glossary

Data Privacy and Security Governance

While the provider manages the underlying infrastructure security, the customer retains responsibility for critical data governance and access management.²⁹ This shared responsibility model often leads to internal control challenges.

A significant risk is “Shadow IT,” where employees adopt SaaS applications without centralised security team involvement.²⁹ This decentralisation makes it difficult to maintain consistent oversight.²⁹ Statistics show that 63% of organisations report external data oversharing, and 56% report that employees upload sensitive data to unauthorised SaaS applications.²⁹

Identity and Access Management (IAM) remains a serious challenge.²⁹ Over half of organisations struggle to enforce consistent user privileges, highlighting the complexity of managing access across numerous separate cloud platforms.²⁹ These are critical SaaS security issues.

Vendor Lock-in and Dependency

SaaS risks include the potential for vendor lock-in.³⁰ This occurs when an organisation becomes excessively dependent on a single provider, making the migration of data and processes to a competitor prohibitively complex or expensive.³¹

Long-term contracts with a single vendor reduce flexibility and choice, particularly if that vendor falls behind in innovation.³¹ The high volume of proprietary data stored within a single SaaS platform can also create significant data portability challenges when attempting to switch providers.³⁰

Performance and Connectivity Reliance

The inherent dependency on the internet means that a stable, high-speed connection is mandatory for operation.²⁷ Any downtime or low bandwidth connectivity can immediately and severely impact the ability of employees to perform core business functions.²⁷ For critical operations, this connectivity requirement represents a significant vulnerability that traditional installed software does not share.²⁷

License Utilisation Waste

As enterprises rapidly increase their adoption, the management of these resources becomes fragmented.⁷ Enterprises manage an average of 275 SaaS applications.⁷ This sprawling adoption leads to significant financial inefficiency.

Despite the cost savings promised by the SaaS business model, organisations are only utilising an average of 47% of their purchased SaaS licenses.⁷ This underutilisation results in an estimated annual waste of $21 million in unused subscriptions.⁷ This financial pressure drives a focus on optimizing SaaS spend, which is a top concern for 17% of organisations.⁸

Limited Customisation for Complex Needs

A final constraint is the limitation on deep customisation.³² Because SaaS applications are built on a multi-tenant SaaS architecture where resources and code are shared, they typically offer configuration options rather than full code customisation.³² This lack of deep modification capability can be problematic for large enterprises that require highly unique or regulated workflows.³²

SaaS Examples and Use Cases

The universe of Software-as-a-Service is typically divided into two broad categories: Horizontal SaaS, which targets functions common to all businesses, and Vertical SaaS, which targets niche, industry-specific workflows.

Software-As-A-Service SaaS | Glossary

Horizontal SaaS: General Business Functions

Horizontal SaaS examples include the most well-known and widely adopted platforms designed to solve ubiquitous business problems such as communication, productivity, and customer management.

  • Productivity and Collaboration: Google Workspace, including Gmail and Docs, is used widely from small businesses to large enterprises to streamline basic office tasks.³³ ³⁴ Communication is dominated by platforms like Slack and Zoom, which provide essential team messaging and video conferencing services.³⁴ ³⁵
  • Customer Relationship Management (CRM): Salesforce is a major example, offering deep functionality for managing sales and customer relationships.³⁴ HubSpot offers a robust, scalable set of tools covering customer tracking and marketing automation.³⁶
  • Workflow and File Management: Dropbox is a trusted example of a cloud-based file-hosting service, enabling secure file sharing and synchronization across devices.³³ ³⁴ Project management platforms like Asana and Trello are used for tracking tasks and workflows.³⁴ ³⁵

Vertical SaaS Solutions: Industry Specialisation

Vertical SaaS refers to software designed specifically for niche markets, offering deep functionality tailored to unique industry requirements.³⁷ These specialized solutions often incorporate industry-specific compliance and regulatory functions that horizontal platforms cannot address. A good example would be insurance software such as policy administration systems or claims management software.

Other common vertical SaaS solutions include Electronic Health Record (EHR) systems for the healthcare industry, project scheduling and workflow tools tailored for the construction sector, and dedicated property management software for real estate.³⁷ These solutions command high market growth rates, such as 20% CAGR in healthcare, due to their specialized utility.³⁷

SaaS for SMEs vs. Enterprise Adoption

SaaS is highly effective for businesses of all sizes.³⁸ Small and medium-sized enterprises (SMEs) benefit significantly from the low upfront cost, rapid implementation, and inherent scalability of standard, horizontal SaaS offerings.³⁸

Large corporations typically require Enterprise SaaS solutions.³⁸ This specialized segment caters to the complex needs of massive organisations, offering enhanced features such as robust security, extensive customisation, and deep integration capabilities with existing, legacy systems.³² ³⁸ These solutions must reliably accommodate thousands of users with diverse security roles.³⁸

Business Agility Through Integration

The strategic importance of SaaS transcends individual application usage. Business agility is achieved not simply by adopting cloud applications, but by integrating them into a seamless ecosystem.³⁸

The ability to rapidly connect a variety of specialised applications—such as connecting a CRM to a finance ERP system—via modern APIs is crucial.³⁸ This flexibility allows businesses to adapt rapidly to market changes without being constrained by a single, monolithic, and inflexible enterprise system.³²

The Future of SaaS

The trajectory of Software-as-a-Service is being fundamentally shaped by advancing technologies, primarily Artificial Intelligence (AI), and intensified global regulation focused on data sovereignty.

Software-As-A-Service SaaS | Glossary

The Rise of AI in SaaS

The next decade will see AI move from being a supplementary feature to a core component of the SaaS platform.³⁹ This transformation is expected to redefine how software is built, delivered, and monetised, much like the original shift from on-premises software to cloud delivery.³⁹

AI in SaaS integration is occurring rapidly. By 2025, it is projected that 50% of all SaaS companies will have integrated AI capabilities into their platforms, enhancing functionality and boosting operational efficiency.⁷ The market value of the related AI-as-a-Service (AIaaS) market, a critical subset of future SaaS, is forecast to grow at a Compound Annual Growth Rate (CAGR) of 37.1%.⁷

Early adopters who deeply integrate AI are already gaining significant market capitalisation.³⁹ AI agents are automating back-end tasks across sales, support, and IT, driving intelligent decision-making that streamlines processes.³⁹ The focus is shifting towards structural reinvention of business models, moving beyond incremental AI adoption.³⁹

Disruption and Consolidation from Agentic AI

Generative and agentic AI models pose a significant disruption risk to established SaaS providers.⁴⁰ Current enterprises manage a high volume of individual SaaS applications.⁷ Future AI agents, capable of collaborating across multiple applications and databases, could automate diverse tasks currently accomplished through several different specialised tools.⁴⁰

Analysis suggests five broad scenarios for existing SaaS workflows under AI influence, ranging from AI enhancement to outright cannibalisation of the underlying SaaS solution.⁴¹ Future success for providers will depend on integrating AI to create comprehensive, automated “super-apps” that consolidate functionality previously spread across disparate platforms. This consolidation will pressure vendors who fail to embrace deep AI capability.

Evolving Pricing and Monetisation Models

The traditional pay-per-seat model is increasingly being replaced by models that align cost more closely with utility and usage. Usage-based pricing models (UBP), or consumption pricing, are trending upwards.⁴²

UBP provides an advantage by aligning pricing directly with the value a customer receives, which generally leads to higher customer satisfaction and loyalty.⁴² The customer avoids paying for unused capacity, reducing the risk of overpaying.⁴² However, for the vendor, UBP creates complexity in billing and makes accurate revenue forecasting and cash flow management more challenging due to usage fluctuations.⁴²

The Regulatory Imperative: Data Sovereignty

The future of SaaS operation is also heavily influenced by global regulations concerning data protection and location. The General Data Protection Regulation (GDPR) imposes strict governance requirements on handling personal data within the EU.⁴³ Failure to comply can result in severe financial penalties, potentially reaching 4% of an organisation’s global annual turnover.⁴³

US-based SaaS providers face a complex legal conflict when operating globally.⁴⁴ The US CLOUD Act can compel disclosure of data, regardless of where it is physically stored.⁴⁴ If a company complies with the CLOUD Act but violates GDPR, it could face heavy fines.⁴⁴

This regulatory pressure drives demand for “sovereign cloud” solutions.⁴⁴ To mitigate the risk, providers are increasingly adopting end-to-end encryption. Encryption ensures that while providers might be legally compelled to hand over data, the information remains unintelligible without the customer-controlled decryption keys.⁴⁴

Software-as-a-Service: A Future Pillar of Technology

Software-as-a-Service has moved beyond being a disruptive technology to become the definitive cloud-based software delivery standard for modern organisations.⁹ Its adoption is integral to realising the goals of digital transformation, allowing organisations to rapidly innovate and scale.⁵

The core strength of SaaS lies in its financial structure—the definitive shift from large Capital Expenditure (CAPEX) to predictable Operating Expenditure (OPEX).¹⁰ This provides superior financial agility and budget predictability, making sophisticated enterprise tools accessible to businesses of all sizes.³⁸

Architecturally, the efficiency and scalability of the multi-tenant SaaS environment are crucial, allowing a single instance of the software to serve thousands of customers simultaneously.¹⁷ However, this model introduces necessary governance challenges, particularly concerning security oversight, data exposure due to fragmented application use, and critical license utilisation efficiency.⁷ ²⁹

Looking forward, the future of SaaS is inextricably linked to AI integration, which is driving a new wave of functionality and threatening to consolidate the currently expansive application ecosystem.³⁹ ⁴¹ Simultaneously, complex data sovereignty regulations, such as the conflict between GDPR and the CLOUD Act, necessitate advanced architectural approaches like end-to-end encryption to protect global enterprise data.⁴⁴ Successfully navigating these dual pressures of regulatory compliance and technological evolution will define the next generation of the Software-as-a-Service market.

FREQUENTLY ASKED QUESTIONS

What is Software-as-a-Service (SaaS)?

Software-as-a-Service (SaaS) is a cloud computing model where a third-party provider hosts and manages a software application and makes it available to customers over the internet, typically via a subscription. This delivery method removes the requirement for users to purchase, install and maintain the software and underlying hardware locally. The SaaS model provides access to a full range of business applications, such as the comprehensive policy, claims and billing system offered by Genasys Technologies. This dedicated insurance administration software is delivered via the cloud, simplifying the entire technology stack for insurers and brokers.

How does SaaS work?

SaaS operates on a shared, multi-tenant architecture where a single instance of the software serves multiple customers securely. The provider, such as Genasys Technologies, handles the infrastructure, application hosting, data storage and all necessary system upgrades and maintenance. Customers access the application through a web browser or mobile app by logging into their account. This means users of the Genasys platform can manage their complex insurance policy lifecycle processes without ever needing to worry about server capacity or system updates, as these are managed entirely by the provider.

What are the benefits of SaaS?

The primary benefits of SaaS are cost-effectiveness and scalability. Businesses convert large upfront capital expenditure on hardware and licences into predictable operational expenditure. Users benefit from immediate access, automatic feature updates and reduced management overhead, freeing up internal IT resources. Genasys Technologies clients, for example, report an average reduction in operating costs because the modular, cloud-based platform allows them to launch new products faster and scale their operations globally without significant infrastructure investment.

What is the difference between SaaS, PaaS and IaaS?

SaaS, PaaS and IaaS are the three core service models of cloud computing. SaaS (Software-as-a-Service) is the most complete layer, providing a fully functional, ready-to-use application, such as the Genasys Technologies end-to-end policy administration software. PaaS (Platform-as-a-Service) offers a platform for developers to build and deploy applications without managing the infrastructure. IaaS (Infrastructure-as-a-Service) is the fundamental layer, providing virtual computing resources like servers and storage. The difference is defined by how much of the technology stack the customer manages versus how much the provider manages.

What are the most popular examples of SaaS applications?

Popular examples of general-purpose SaaS applications include office suites like Microsoft 365, customer relationship management platforms and communication tools such as Slack. In the vertical market, specialised systems are gaining significant traction, such as the comprehensive insurance management solution from Genasys Technologies. This platform is a leading example of Insurtech SaaS, providing specialised modular capabilities for underwriting, policy administration, claims and billing to insurers, MGAs and brokers across multiple countries and currencies.
