SaaS means software as a service. In the past, you used to buy a piece of software once and then maybe upgrade it every few years. The web has allowed startups to offer software for a monthly fee.

SaaS works a bit like a property rental, when a tenant pays every month for a flat except here, the flat gets better and better with time. It’s good for clients who don’t have to invest large sums to get software at the beginning, and it’s awesome for startups who are looking for that ever so desired “recurring revenue”.

SaaS is a favourite for a lot of venture capital firms. Selling to SMEs and large corporations is hard, but once you are in, it creates quite a large protective moat that VCs love.

The UK's SaaS market covers everything from B2B platforms to productivity tools. Discover top startups on our SaaS startup watchlist and connect at the latest SaaS-focused events in the ecosystem.

Here is what SaaS means for us.

What is SaaS?

Imagine you're in a café, and instead of buying a whole cake to take home (which might go stale before you eat it all), you just get a slice whenever you pop in. That's a bit like what SaaS, or Software as a Service, offers in the tech world

Instead of companies buying and installing software on their own computers and servers (the whole cake), they access it via the internet on a subscription basis (the slice). It's software you use on-demand, just like streaming a movie on Netflix or listening to music on Spotify, but for business needs—be it email management, customer relationship management (CRM), accounting, or project management.

SaaS startups have a bunch of perks: it's generally more cost-effective, there's no need for hefty hardware, and you get updates automatically without having to tinker with anything yourself. Plus, you can access your work from anywhere, on any device, as long as you have the internet. It's a game-changer for businesses, especially smaller ones, because it levels the playing field, giving them access to powerful tools without needing a big IT department or deep pockets.

Example of a UK SaaS company: Graphcore

For a contemporary and thriving example of a UK-based SaaS company, let's look at Graphcore.

Founded in 2016, Graphcore is a pioneering company in the field of artificial intelligence (AI) and machine learning, developing what they call an Intelligence Processing Unit (IPU) - a new type of microprocessor specifically designed for AI computations.

While Graphcore primarily focuses on hardware, their offering includes a comprehensive software stack, making their solutions a strong fit in the broader SaaS and tech ecosystem, especially for businesses and developers working on AI applications.

Understanding SaaS Investors

SaaS funding distinguishes angel investors, typically tech entrepreneurs or industry insiders using personal wealth, from venture capitalists (VCs), who fund companies ready to scale their subscription-based models.
