“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.”

What founders say

In their words

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

“I turned to Sam at FounderCatalyst after being misguided by his competitors about eligibility for SEIS as an investor. I have spent three weeks emailing HMRC and my legal team and could not get a straight answer. Sam gave me a definitive explanation the following day. From now on I will be using FounderCatalyst for all my equity funding legal needs!”

“Having spoken with FounderCatalyst some 3-years ago, to get ready to raise with SEIS/EIS assurance done, I was ready to go. Or so I thought! I decided to focus on organic growth to prove the business. 3-years later I'm ready to go for the raise and FounderCatalyst kept their side of deal and have my funding round open and ready to go - no extra money required. Love these guys!!!”

“FounderCatalyst is not only a great platform but also a great community. I moved to FC after meeting founder Sam Simpson, and straightaway felt it was the right platform to support our needs - their service is fab, the fee structure is fair and transparent, and the platform is straightforward and easy to use. Sam himself is super engaged and responsive, and the FC WhatsApp group is a brilliant, collaborative and supportive community to be part of. Highly recommend!”

“We used another provider for our SEIS/EIS advance approval application but, because our TopCo is overseas and we have a touchpoint with digital assets, HMRC had some queries that our provider was not able to advise on. Sam/FounderCatalyst gave quick and valuable support with our responses.”

“We were initially recommended FounderCatalyst by an advisor to help us through our SEIS/EIS advanced assurance, and they have been nothing short of fantastic ever since. We ran our first fundraise through their platform, and will, without a doubt, use them again for future raises. As an early stage start-up founder I have leant on the team a lot and they have always been prompt (even at 11pm at night!), understanding & right on the money with their advice & support. Thank you FounderCatalyst!”
