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.”

“FounderCatalyst were first class from start to finish. The help provided in navigating the minefield of SEIS/EIS advance assurance and fundraising legal documentation has been invaluable. They never tired of answered my questions enabling a smooth process for us founders and our investors in as far afield as Australia. I cannot recommend them highly enough.”

“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.”

“The level of service you receive is not in line with how much you pay. Typical SaaS businesses will take your payment and offer no support but I would argue you receive a lot more support and service than you pay for. Sam is a wealth of knowledge as well”

“Our fundraising was anything BUT straightforward. Without the help from the team from FounderCatalyst, it very well might not have happened at all. There are other very good providers like this in the market, but none of them give the care and community that FC does. As the various wobbles and pitfalls came for us, it became clear we were in good hands. I not only recommend, I implore.”

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.””
