“Phenomenal! Sam and his team at FounderCatalyst helped demystify our route ahead and provided invaluable insight and support in obtaining our SEIS Advanced Assurance. I don't believe we would have done it without him. What's more, the approval only took 5.5 business hours from submission. Far faster than HMRC was advising themselves. I firmly believe this was down to the solid preparation and support provided by FounderCatalyst.”

“Ronseal for fund raises - they do what they say on the tin! Chose FounderCatalyst for our first fundraise over Vestd and SeedLegals after conversations with all three. Reason for choosing - Sam. Direct, no nonsense advice from someone who has been there and done it. Service once we were onboard did not disappoint. Clear guidance and instructions with questions answered quickly and comprehensively. No hesitation in recommending to other founders.”

“I am doing a funding round using another legal paperwork provider but hit an issue with our SEIS/EIS advance assurance being queried. I wasn’t entirely confident in the proposed response to HMRC and someone recommended I speak to the FC team. They helped me to improve my response and their support led to a positive response. Amazingly helpful and knowledgeable team, even for someone who wasn’t a customer. I've recommended them to colleagues already and will be switching to FC for our next round!”
