“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!”

“FounderCatalyst could not have been more helpful and supportive throughout our SEIS process.They worked diligently to help us get advance assurance much faster than we thought was possible. They went above and beyond the basic advance assurance process, and played a crucial role in helping us to secure funding. I can not recommend FounderCatalyst enough.”

“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.”

“Rapid Assurance: Exceptional Service by FounderCatalyst and Sam - I recently worked with FounderCatalyst and was thoroughly impressed by their exceptional service. From start to finish, the experience was smooth and efficient. Sam provided prompt, helpful responses - answering every question I had and guiding me through the process with clarity and ease. Thanks to his and the team's dedication, I was able to complete the form quickly and even received full advance assurance in less than 8 working hours! This level of responsiveness and professionalism is rare, and it truly made all the difference. I highly recommend FounderCatalyst and thank Sam for his outstanding support!”
