“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.”

“We met FounderCatalyst through the Startup 2 Standup Community, and were immediately impressed with their proactive approach to supporting founders. Their guidance from the very start with the advance assurance submission to closing our initial tranche has been truly invaluable, combined with the auto-documentation and flexibility the platform gives you at every stage in the round, makes FC the best choice for pre-seed startups.”

“FounderCatalyst was introduced to me by a former colleague whilst I was exploring personal investment opportunities in companies already using the FC platform. After a briefing with Sam Simpson, I decided to use the platform for my own start-up Soul Padel. The S/EIS process couldn’t have been easier and simpler to understand and Sam’s hands-on guidance was much appreciated throughout. We then launched our SEIS round with FounderCatalyst and being a first time founder, it was enormously helpful to have the structured guides, articles and the hugely beneficial community of founders to tap into. Not only that but the ecosystem of professionals associated with the FC platform enabled me to seek cost effective advice early. We recently closed our first round after securing investment from a single HNW individual, without the use of costly lawyers or lengthy complex negotiations. I can’t recommend FounderCatalyst highly enough. If you are looking to start your own business and raise investment, you need to start your process with FounderCatalyst. It’s much much cheaper than what you’ll find elsewhere but the best thing is, Sam as founder will be your friend, guide and mentor throughout. Nowhere else gives you that level of service. It’s so good, I’ve also invested in FounderCatalyst platform users because I know their governance and structure is sound and very well put together. It’s more than just a service, it’s a community.”

“I’ve been using FounderCatalyst since July, and as a first-time founder the difference has been genuinely meaningful. My first conversation with Max and immediately felt different. It wasn’t a sales call. It was human, thoughtful, and grounded in real understanding. I felt heard. There was empathy and expertise, which is rare when you’re navigating something as unfamiliar as SEIS for the first time. I needed hands-on support to set up SEIS, and the whole process was incredibly smooth. The guidance was clear, practical, and seamless from start to finish. No hidden costs, no surprises. That clarity, combined with the quality of the conversations, is what turned me into a very happy customer early on. In the 7 months since, FounderCatalyst has never let me down. Questions are answered quickly, the resources are genuinely useful, and the seminars are well thought through. But what really stands out is the community. The WhatsApp group is exceptional: founders sharing candid experiences, advice, and lessons without ego. Sam is consistently present and on top of things, and this is a safe space, both supportive and practical. FounderCatalyst, and the community around it, has become a key pillar of my startup journey. The learning, the empathy, and the steady support from Sam and the wider group have been invaluable. As a founder, that kind of environment makes a real difference.”
