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.”

What founders say

In their words

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

“Founders always need external, expert support, and never more so than in the area of handling HMRC and SEIS/EIS. This is where the big learning curves come from, and you don’t want to get this wrong - it follows you for a long time. The team at FounderCatalyst are wonderfully human, knowledgable, accessible, experienced and focus on helping the Founder - the human. ”

“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!!!”

“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.”

“Our experience using FounderCatalyst was quick and easy. FounderCatalyst have turned the onerous task of raising funds into an easy process for not only ourselves, but our investors too. I would recommend FC to anyone raising their seed round.”

“The FounderCatalyst team turned my advance assurance application around in just 2 working days and we had a positive response back from HMRC within a week. Their assistance with preparing my Investors Deck and forecast model was invaluable. We highly recommend using FounderCatalyst to other founders!”

“Blown away by the service and value: I was under pressure to close a funding round swiftly before the end of the tax year and the FC team were on point and held my hand right through the process. I’ve tried SeedLegals and the value we get from FounderCatalyst is way beyond - the support from FC is immediate and precise, compared with slow and inconsistent with SL.”

“Excellent service - comprehensive coverage of a tricky business area. I received huge support as I applied for Advanced Assurance for my Padel Tennis company. With their astute guidance I was able to get all the right documents in place and apply for AA and receive a positive response in less than 48 hours. I would 100% recommend FounderCatalyst to anyone.”

“FounderCatalyst were incredible in helping us close our SEIS round ahead of a tight deadline. They offered great 1-1 support through the entire S/EIS Advance Assurance and fundraise process. I couldn’t recommend Sam and the team more highly to any founders raising investment!”
