Case study

£2.8M raised for just £1,450

And higher rated than competitors, according to Trustpilot.

“As a founder building an agentic AI platform for workforce planning in supply chains, I'm always looking for tools that save time and money. FounderCatalyst delivered both - the process was seamless, and it cost less than a tenth of what I was quoted elsewhere. It let us stay focused on growing the business, not buried in fundraising admin.”

In their words

A sample of testimonials from founders, advisors and investors who have worked with us.

“The whole team is absolutely amazing !! Right from Sam to Emma who helped us with our application - are a delight to work with and know exactly what they are doing. I was really nervous about the EIS, but in the end the whole process was super easy thanks to FC.”

“We've been using FC since we founded our company in January 2024. They secured our SEIS approval from HMRC and have helped us close two investment rounds; Pre-Seed and an agile investment round. We were new to this and we'd have been lost with FC. Not just the platform itself, but Sam, Max, Andy and the team who are always there for us, for our questions, and for our suggestions on improvements. They're the absolute best and I recommend them to every new startup founder I meet; no referral commissions needed, they're just that good.”

“FounderCatalyst were really responsive when we used them for our raise and always had clear guidance - even when we were asking them things that were clearly documented on their website :-). We chose them because their price was incredibly reasonable, and I'm glad to say the service exceeded our expectations at that price point.”

“Sam and team provide a faultless service. I've been incredibly impressed with the rapid response time of any questions I send, and the level of detail and reassurance provided to make sure we fully understand the process. We flew through the HMRC (S)EIS Advance Assurance process: submitting it just before 5pm on a Monday, and having received confirmation of it by 1:30pm the next day! Can't get much better than that. Really very happy to have chosen FounderCatalyst.”
