The software-as-a-service (SaaS) market is one of the fastest-growing sectors in the world. It’s no surprise, therefore, that the sector is an attractive field for entrepreneurs and investors alike. In fact, our data shows that nearly 9% of high-growth companies in the UK are SaaS businesses.
In this article, we’ve profiled 15 UK-based SaaS companies to watch this year, from established firms to emerging startups innovating in this space. You’ll find three rankings—first, a ranking of the most successful B2B and B2C SaaS businesses by the amount of equity funding they’ve received to date, followed by top SaaS startups still in their early stages of growth.
What is software-as-a-service?
Before delving into our list of the top 15 SaaS companies in the UK, it’s worth exploring what exactly SaaS businesses do and the major players in the global SaaS market.
A SaaS company develops software which fulfils a certain service or function, often made accessible to users through an internet or cloud platform. As well as the initial software development, SaaS companies continue to host, update, and upgrade their products, generally with the aim of improving overall user experience.
SaaS companies work across a wide range of industries, including fintech, big data, artificial intelligence (AI) and e-commerce. There are countless SaaS solutions in existence today, from human resources, customer relationship management (CRM) and web development, to social media and email marketing automation, enterprise resource planning (ERP), and project management.

The biggest players in the SaaS industry
How does a SaaS business model work?
Different types of SaaS companies: B2B v B2C
SaaS companies can also be differentiated by who their target customer is. As the name suggests, business-to-consumer (B2C) SaaS companies develop software solutions for personal use by consumers. Business-to-business (B2B) SaaS companies aim their product offering at other companies, such as by helping them to perform better, manage their operations, or meet their customer needs. Some SaaS companies have designed both B2B and B2C SaaS products, however, offering services to both consumers and businesses.
Having now discussed the basics around SaaS companies, read on to discover our top 15 SaaS companies in the UK…
