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.”

“I’m so glad I was introduced to FounderCatalyst. They are the absolute go-to team for SEIS Assurance and fundraising legal paperwork. Their advice is succinct, and any questions are answered quickly, usually within an hour which is incredible service. The FounderCatalyst community is super supportive. I’ve seen it grow tenfold in less than 12 months, I guess that says it all…”

“Prior to working with FounderCatalyst, we had conducted the legalities of our first funding round via accountants and lawyers and found a real disconnect between the two. We reached out to FounderCatalyst for round 2 and couldn’t be happier with the service. They are on hand to personally deal with any requests or questions - there is a real accountability of the full process and depth of knowledge that you’re able to leverage. We would not go elsewhere for another round.”

“So far, so good. Have valued their responsiveness, advice and breadth of, no nonsense, step by step guides. They also helped us get SEIS/EIS pre assurance within 7 days. I wish I'd found them sooner.”

“Best decision we made as founders was switching to FounderCatalyst. Wasted a load of money with Seed Legals originally. Advice from some junior guys there vs Sam (a multiple exited founder and investor himself) doesn’t even compare. Sam had to spent a lot of time unpicking bad advice we had previously but did so with minimum fuss and no extra cost. Can’t recommend enough.”
