Case study

£2.8M raised for just £1,450

And higher rated than competitors, according to Trustpilot.

“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.

“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.”

“We've been using FC since we founded our company in January 2024. They secured our SEIS approval from HMRC and have helped us close two investment rounds; Pre-Seed and an agile investment round. We were new to this and we'd have been lost with FC. Not just the platform itself, but Sam, Max, Andy and the team who are always there for us, for our questions, and for our suggestions on improvements. They're the absolute best and I recommend them to every new startup founder I meet; no referral commissions needed, they're just that good.”

“FounderCatalyst have been excellent from start to finish. SEIS/EIS advance assurance support at a fixed rate and with lots of support. The best bit is the ongoing community of support- wouldn't go anywhere else and we'll be engaging in the new products/services which Sam & the Team bring out this year.”

“I've got a background in law, so I'm comfortable with the mechanics of a funding round. The FounderCatalyst service is unique though - they give you personal support and use their experience to guide you through the key decisions - something only exited founders and angels investors can provide.”

“Our experience using FounderCatalyst was quick and easy. FounderCatalyst have turned the onerous task of raising funds into an easy process for not only ourselves, but our investors too. I would recommend FC to anyone raising their seed round.”

“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 have been amazing, not only did they get the SEIS assurance as promised but the back up and additional services they provide as part of the service are invaluable. The community they create with other founders is also a great source of shared knowledge and support. Couldn’t recommend highly enough, thanks FC!”
