“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.

“We recently used FounderCatalyst to support our SEIS application, and the experience was exceptional from start to finish. Their communication was consistently clear, fast, and incredibly helpful — every question we had was answered promptly and with real expertise. The whole process felt streamlined and stress-free thanks to their guidance. I would happily recommend FounderCatalyst to anyone preparing an SEIS application. Their professionalism, responsiveness, and deep understanding of the process make them an outstanding partner for any startup navigating early-stage investment.”

“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'm a technology lawyer by background so I test a lot of technology all the time and FounderCatalyst is very easy to use. When you're starting out, cash is tight, but their fixed fee gave us unlimited EMI and unapproved options, plus every vesting variation we needed - time based, conditional, exit only. I didn't think twice!”

“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!”

“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!”

“FounderCatalyst is simple to use, the price has no hidden extras or subscription mode, and is extremely good value. The back office support and advisors are exceptionally knowledgable and responsive. I have invested in over 45 Startups and had 3 of my own startups use the platform, and would recommend it to any founder or investor. If a founder is not happy with the level of legal documents for the cost then it is a big red flag that your money may not be spent on the most important things in the business. First rate product.”
