What founders say

In their words

A sample of testimonials from founders, advisors and investors who have worked with us.

“Big fan of the team at Founder Catalyst. Despite having built divisions in startups from the ground up for the past 10 years, this is my first time as a founder and I naturally have a lot of questions and learning to do. Sam and the team have been great teachers and advisors. They have guided me through the process every step of the way - from my first priced round, to getting SEIS/EIS advanced assurance. Key differentiator - they'll be real and straight with you about how to get things done. If you're lacking in a certain area, they'll tell you. This is invaluable for a first-time founder given the very distracting and contradictory noise surrounding the build of a business. I had considered Seed Legals before Founder Catalyst and found their approach to be purely sales driven rather than focused on customer care & quality of input. Another founder recommended FounderCatalyst and I'm so glad they did. Finally, a big shoutout to Charles who has been a game changer in customised legal advice.”

“Sam and the team at FounderCatalyst are the best in the business. From taking us smoothly (and speedily!) through the complicated SEIS/EIS advance assurance process and providing ongoing support, to creating an incredible and extremely supportive community for like minded founders going through the same process, I can’t recommend FC highly enough!”

“FounderCatalyst's Agile functionality is perfect for navigating the messy reality of fundraising. It's incredibly simple to use, and takes the sting out of the otherwise intimidating paperwork. The FC team themselves are always going above and beyond - answering emails and lending a hand at awkward hours.”

“FounderCatalyst is a must for ALL businesses looking to raise capital. As a qualified accountant even I struggle with the legalities, paperwork and even dealing with HMRC to obtain advance assurance. FounderCatalyst removes all these headaches and unlike their competitors the co-founders are always on hand to provide valuable support every step of the way. Quite simply they have become an invaluable 'department' of my business and I'm very grateful to be working with them.”

“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.”

“Sam and the FounderCatalyst are attentive, diligent and extremely helpful with all things associated with a funding round, particularly, when it comes to legals. Sam has built a supportive and thriving community and that's a testament to his founder-first approach. I'd highly recommend his services to any founder looking to raise investment.”

“As a solo-founder and 'start-up newbie', the service, support, specialism and community that FounderCatalyst offers is invaluable. From formal paperwork completion to the 'Friendly Founders' WhatsApp chat, I just wish that I had joined sooner...”

“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.”

“It was a pleasure working with FounderCatalyst. As of the first meeting, Sam was very involved in the whole process and made it very easy for us to get us investor ready faster than we could have ever imagined. We can only recommend the service and are about to use his services soon again.”
