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.”

“Wonderful to be in the FounderCatalyst family. We get so much support! ”

“I switched from SeedLegals to FounderCatalyst which has proved both cheaper and the customer service is infinitely better. Everything is included in the one off fee so you aren't hit by extra fees you don't expect. The team includes ex founders and investors so you get both technical and tactical support, which wasn't the case with SeedLegals. I also get very rapid responses to my emails, which was a refreshing change. ”

“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.”

“FounderCatalyst was incredible to work with from start-to-end for our pre-seed round. They were meticulous, prompt to reply, and handled numerous customisations. I've used other legal services and platforms which came up too expensive and prone to errors. FounderCatalyst is miles ahead in terms of service, value-for-money and legal expertise.”
