“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.

“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!”

“We incorporated in 2000 and started trading almost immediately. We recently started looking to expand our business into new territories and needed an equity investment to facilitate that. Unfortunately, attracting angel investment in the UK is very hard without offering SEIS or EIS. We thought the ship had sailed until FounderCatalyst mentioned a little-known EIS provision known as Condition B. Long story short, the FounderCatalyst team successfully secured EIS advance assurance and we are now raising using that scheme.”

“The best investment we made was using FounderCatalyst for the legal work. It's really good value, the platform was easy to use and we had amazing support throughout from their CEO, Sam Simpson. I would absolutely recommend it to all founders!”

“I had a really important meeting with an investor and had realised my cap table needed adjusting since we had made a few changes in the last few months. We had been using another platform for our documentation, but unfortunately, time was of the essence, and I needed something I could send on ASAP, I needed help with it and unfortunately, this was not something they could provide. My first thought was of Sam. I have known Sam for the last few years whilst building Bezzelle and knew that he was someone who could potentially save the day, I can confirm not only brilliant with all things funding, also a super nice guy too! Awaiting the outcome of the investment meeting but he has a new customer for our next funding round! (Sorry in advance for all my share related queries!)”

““A Lifesaver for First-Time Founders! As a first-time founder raising funds for the first time, I was overwhelmed by the complexity of documents like the SH01 and EIS3. Founder Catalyst made the entire process so much easier. Sam was incredibly helpful and always accessible, whether via video calls, direct messages, or through the Founder Catalyst WhatsApp group, which is filled with a supportive and knowledgeable founder community.””

“This was my first time raising funds and using SEIS, and FounderCatalyst made the process so much easier. They helped me secure Advance Assurance and were incredibly responsive and helpful throughout. Even though they have detailed articles on their site, they patiently answered all my basic questions. Their pricing is also excellent—just a one-time fee, which is great value. The service felt like an Amazon-level experience. I'm happy to say I’ve now raised my first round of funding, and I highly recommend FounderCatalyst to any first-time founder.”

“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.”
