FounderCatalyst delivered both - the process was seamless, and it cost less than a tenth of what I was quoted elsewhere. It let us stay focused on growing the business, not buried in fundraising admin.”

“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 is more than just a digital fundraising platform—it's a true game changer for entrepreneurs. From day one, the level of support we received was unmatched. The team is practically on call 24/7, ready to answer every question we had, and they didn’t just give us answers—they took the time to explain the entire process in detail. This personal touch is worth its weight in gold. One of the standout features is the community. It’s filled with experts, successful ex-founders, investors, and fellow entrepreneurs, all actively engaged in fundraising. And when I say active, I mean good active—it's a highly useful, focused community with zero fluff or random chatter. Every discussion is purposeful, providing real value to your fundraising journey. FounderCatalyst helped us secure an ASA within weeks and managed all of HMRC’s queries seamlessly. The platform made the entire process so much smoother than I ever imagined. If you're looking for a platform that combines cutting-edge technology with real human expertise and support, look no further than FounderCatalyst. It's been absolutely pivotal in our fundraising success!”

Their professionalism, responsiveness, and deep understanding of the process make them an outstanding partner for any startup navigating early-stage investment.”

““FounderCatalyst have been really helpful for our startups’ investment round. We received advanced assurance for our SEIS/EIS application within 2 days of submitting it through FounderCatalyst, and the various support systems, pitch reviews and Whatsapp groups have been great as well. On top of all that, we’ve also set up all of our legal documentation and data room through FounderCatalyst, which is amazing.””

“FounderCatalyst is not only a great platform but also a great community. I moved to FC after meeting founder Sam Simpson, and straightaway felt it was the right platform to support our needs - their service is fab, the fee structure is fair and transparent, and the platform is straightforward and easy to use. Sam himself is super engaged and responsive, and the FC WhatsApp group is a brilliant, collaborative and supportive community to be part of. Highly recommend!”

“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!”
