“The process was incredibly easy, and it makes sense why this service exists for start-ups. I would highly recommend FounderCatalyst to anyone considering raising money and needing SEIS/EIS advanced assurance. Whilst it’s unnecessary because the platform is so slick and automated, Sam and the team are friendly and always available to help if investors have any questions. 10/10 service!!”

“We were unsure how to approach SEIS/EIS advance assurance, but FounderCatalyst made the process a breeze. Even better, we had a positive advance assurance confirmed by HMRC in less than five and a half hours! Crazy good. Sam and his team are incredibly knowledgable, clear, helpful and thorough. We could not recommend them more!”

“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.”

“We met FounderCatalyst through the Startup 2 Standup Community, and were immediately impressed with their proactive approach to supporting founders. Their guidance from the very start with the advance assurance submission to closing our initial tranche has been truly invaluable, combined with the auto-documentation and flexibility the platform gives you at every stage in the round, makes FC the best choice for pre-seed startups.”
