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 had little knowledge of the legal processes of raising investment. Our CCO recommended FounderCatalyst and we have both been very glad we chose this route. The FounderCatalyst team led us through the system personally and the online portal, including electronic document signing, was fantastic.”

“If you want speed, service and cost efficiency. FC are your guys. - Wow! FC is another level of good. From my first intro call with Sam (he was keen to explain and simplify the process for us) to concluding investment and issuing the SEIS3 certificates to investors, the process has been so intuitive and efficient....and speedy! The human response time on their support is remarkable. I used the 'other' guys for years and this is a whole different experience...and MUCH cheaper. Bravo.”

“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!”

“Big fan of the team at Founder Catalyst. Despite having built divisions in startups from the ground up for the past 10 years, this is my first time as a founder and I naturally have a lot of questions and learning to do. Sam and the team have been great teachers and advisors. They have guided me through the process every step of the way - from my first priced round, to getting SEIS/EIS advanced assurance. Key differentiator - they'll be real and straight with you about how to get things done. If you're lacking in a certain area, they'll tell you. This is invaluable for a first-time founder given the very distracting and contradictory noise surrounding the build of a business. I had considered Seed Legals before Founder Catalyst and found their approach to be purely sales driven rather than focused on customer care & quality of input. Another founder recommended FounderCatalyst and I'm so glad they did. Finally, a big shoutout to Charles who has been a game changer in customised legal advice.”
