Startups in the UK
The UK has a thriving startup scene, with London as a global tech hub. Successful startups like Revolut, Deliveroo, Darktrace, and BenevolentAI have emerged. Government programs like EIS and SEIS, along with tax incentives, support these ventures. Universities, accelerators, and coworking spaces also contribute to startup growth.
What is SaaS?
B2B SaaS (Business-to-Business Software-as-a-Service) refers to cloud-based software solutions specifically designed for businesses.
Commonly, people also use the term saas to mean companies that are funded by VC, growing fast, and generally innovative.
It is this combination of factors that makes it difficult to define: what really is a B2B SaaS?
This is how we have refined the search with Tactic.
How we created this list
Starting with a list of funded companies founded after 2008 (within the last 15 years), we considered companies with a scale of 50 to 5000 employees, without filtering by industry. This approach ensures that we don't overlook any good B2B SaaS companies, even if they are classified in a different industry than “Information Technology”.
We evaluated factors such as the presence of a 'contact sales' or 'request demo' button on the company website, as well as a dedicated pricing page, to narrow down the list. Tactic's LLMs helped us differentiate between B2B and B2C companies.
Finally, we added more details about the company description, industry, headcount, and funding to ensure accurate and clean data.
How we ranked and prioritized this list
“SaaS” companies are one of the most generated datasets on Tactic. Its in such high demand, we did some customer research about it.
Turns out, SaaS is also a shortcut for customers to refer to venture capital funded, fast growth software companies.
So, to produce this ranked list of companies, we went a much simpler path. Using Tactic’s scoring tool, we simply scored companies 50% on how recently they have been founded, and 50% on how big they got in that period.
How many VC backed B2B SaaS companies are there in the UK?
There are about 600 VC backed B2B SaaS companies in the United Kingdom, according to the criteria above – 50-5000 employees, founded after 2018, B2B, and offers cloud based software as a subscription.
Here's the first 45 companies in this dataset. If you'd like to ask additional questions (e.g. who has monthly pricing?), integrate this into your CRM, or access the rest of the dataset, please contact us for a chat!
