“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.”

“As a first-time founder, the process of raising equity investment can seem like a complex puzzle. The FounderCatalyst platform has guided me through the process of generating investment documents, collecting signatures from investors, tracking funds and closing the round. When I needed that extra help solving the puzzle, the team were just an email away addressing queries with patience. Furthermore, they also simplified the mystical ritual of the S/EIS advance assurance application to make our investment opportunity shine even brighter. ”

“FounderCatalyst was incredible to work with from start-to-end for our pre-seed round. They were meticulous, prompt to reply, and handled numerous customisations. I've used other legal services and platforms which came up too expensive and prone to errors. FounderCatalyst is miles ahead in terms of service, value-for-money and legal expertise.”
