“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!”

Their advice is succinct, and any questions are answered quickly, usually within an hour which is incredible service. The FounderCatalyst community is super supportive. I’ve seen it grow tenfold in less than 12 months, I guess that says it all…”
