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.”

“Excellent service - comprehensive coverage of a tricky business area. I received huge support as I applied for Advanced Assurance for my Padel Tennis company. With their astute guidance I was able to get all the right documents in place and apply for AA and receive a positive response in less than 48 hours. I would 100% recommend FounderCatalyst to anyone.”

“Sam and team provide a faultless service. I've been incredibly impressed with the rapid response time of any questions I send, and the level of detail and reassurance provided to make sure we fully understand the process. We flew through the HMRC (S)EIS Advance Assurance process: submitting it just before 5pm on a Monday, and having received confirmation of it by 1:30pm the next day! Can't get much better than that. Really very happy to have chosen FounderCatalyst.”

“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.”
