“As a founder building an agentic AI platform for workforce planning in supply chains, I'm always looking for tools that save time and money. 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.”

What founders say

In their words

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

“FounderCatalyst made it simple for me to apply for HMRC SEIS Advance Assurance and set up my funding round. Using helpful templates provided by FounderCatalyst, I spent a few weeks refining my pitch deck and forecast. Once I was ready, it took less than an hour to get everything online and submitted to HMRC. I hit submit at 11am on a Thursday and by 9am the following Monday, I had the good news from HMRC!”

“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.”

“Such a super-easy to use platform. Opened and closed a round and received the funds within 48-hours! Also, the business owner Sam is knowledgeable and supportive in other areas such as applications for SEIS/ EIS and the cost is lower than any other alternative - I checked!”

“The whole experience of raising investment with FounderCatalyst has been exceptional. Having been a founder before and as Entrepreneur in Residence at the University of Bath and SetSquared, I've experienced either first or second hand most ways of managing investment rounds, through crowd platforms to employing teams of expensive lawyers and advisors. I'd heard about FounderCatalyst and had always been intrigued. So, when it came time to raise our Seed round for Earswitch we thought it time to try them out. The system, simplicity and support made the whole process a doddle and we're now about to start our 4th round on the platform. Very highly recommended! ”

“The intricacies of an equity raise are really niche and difficult to manage. Specifically, the legals that underpin the entire process aren't the sexiest part but are probably the most important. The team at FounderCatalyst ensured that everything was managed seamlessly with Seedrs. I felt in safe hands throughout the raise knowing that they were in the background, lining everything up from a legal perspective.”

“FounderCatalyst has been fantastic - use this service!! We recently raised via CrowdCube and FounderCatalyst was very efficient at sorting out the legal paperwork, which removed all the stress from us. We are a new start-up and they made the legal processes of funding rounds incredibly easy to navigate. They sorted out our advance assurance in record speed. The team is incredibly knowledgeable (not only legal experts but exited founders) and they also have a great community on WhatsApp with other founders. ”
