have to say about us
In their words
A sample of testimonials from founders, advisors and investors who have worked with us.
“Seven weeks ago, I had no clue what Seis/EIS INVESTMENT WAS! as a solo founder I’ve been finding my way on the rollercoaster of building a business front scratch. I had signed up with a competitor 2 weeks before I found myself on a webinar with Sam Simpson from Founder Catalyst. As an exited founder and current investor, Sam set up Founders Catalyst to support entrepreneurs to understand, prepare for and then secure investment. What struck me about the webinar was that I understood everything he said - it finally made sense. I immediately cancelled my existing agreement (having felt totally overwhelmed and unsupported once they had their fee) and moved to Founders Catalyst. Today I closed my first round of investment- 5 weeks since I attended the webinar! Shout out to Sam (has walked the walk and gives his time and expertise generously), Emma (for walking me through the setting up process) Max (so patient! And knowledgeable). Oh, and when you send a support message, a human messages you back, quickly! I’ll now embark on the confirmation paperwork (investment is a journey) but taking a minute to show true appreciation for a business that delivers.”
“FoundersCatalyst has been second to none in supporting our raise, with Sam and the team offering invaluable guidance to ensure a seamless round for us and our investors. In particular, their expertise in navigating complex SEIS/EIS compliance matters has saved us a significant amount of time and stress. I cannot recommend them enough to any startup currently fundraising.”
“Really helpful team who helped us secure our EIS advance assurance in super quick time. Very competitively priced too - thanks!”
“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 could not have been more helpful and supportive throughout our SEIS process.They worked diligently to help us get advance assurance much faster than we thought was possible. They went above and beyond the basic advance assurance process, and played a crucial role in helping us to secure funding. I can not recommend FounderCatalyst enough.”
“We used another provider for our SEIS/EIS advance approval application but, because our TopCo is overseas and we have a touchpoint with digital assets, HMRC had some queries that our provider was not able to advise on. Sam/FounderCatalyst gave quick and valuable support with our responses.”
“FounderCatalyst have been amazing, not only did they get the SEIS assurance as promised but the back up and additional services they provide as part of the service are invaluable. The community they create with other founders is also a great source of shared knowledge and support. Couldn’t recommend highly enough, thanks FC!”
“We used FounderCatalyst to do our SEIS advance assurance, our initial fundraising round, and subsequent agile round. The experience throughout all this was incredible. The level of personal service and attention to detail is unmatched. I have previously used a competitor service and it doesn't come close to what FounderCatalyst offers. We will continue using them and cannot recommend Sam and the team highly enough.”
“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!”
