“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. ”

“I had a fantastic experience with FoundersCatalyst from start to finish (and continue to receive ongoing support). They responded quickly to my initial inquiry, providing excellent guides and transparent information about fees, how the platform works, and what to expect. After following their templates and guidance, we submitted our pitch deck and financial forecast, and Founders Catalyst handled our SEIS application to HMRC. We received approval within three weeks, with no complications. The platform is straightforward to set up, offering term sheets, a data room etc., and a wealth of video/blog content to help. For specific inquiries, their ticketing system is incredibly responsive—usually within a few hours. On top of that, there’s an excellent community on WhatsApp, which includes all the FC staff as well as peers who are friendly, welcoming, and happy to answer even our "stupid questions" throughout the entire funding journey. I can't recommend FoundersCatalyst enough. The founder, Sam, is exceptionally knowledgeable and very generous with his time, supporting every founder to succeed in their funding rounds.”

“FounderCatalyst has been fantastic - use this service!! We recently raised via CrowdCube and FounderCatalyst was very efficient at sorting out the legal paperwork, which removed all the stress from us. We are a new start-up and they made the legal processes of funding rounds incredibly easy to navigate. They sorted out our advance assurance in record speed. The team is incredibly knowledgeable (not only legal experts but exited founders) and they also have a great community on WhatsApp with other founders. ”

“FounderCatalyst is a must for ALL businesses looking to raise capital. As a qualified accountant even I struggle with the legalities, paperwork and even dealing with HMRC to obtain advance assurance. FounderCatalyst removes all these headaches and unlike their competitors the co-founders are always on hand to provide valuable support every step of the way. Quite simply they have become an invaluable 'department' of my business and I'm very grateful to be working with them.”

“If you want speed, service and cost efficiency. FC are your guys. - Wow! FC is another level of good. From my first intro call with Sam (he was keen to explain and simplify the process for us) to concluding investment and issuing the SEIS3 certificates to investors, the process has been so intuitive and efficient....and speedy! The human response time on their support is remarkable. I used the 'other' guys for years and this is a whole different experience...and MUCH cheaper. Bravo.”

“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.”
