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.

“Blown away by the service and value: I was under pressure to close a funding round swiftly before the end of the tax year and the FC team were on point and held my hand right through the process. I’ve tried SeedLegals and the value we get from FounderCatalyst is way beyond - the support from FC is immediate and precise, compared with slow and inconsistent with SL.”

“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. ”

“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.”

“Having spoken with FounderCatalyst some 3-years ago, to get ready to raise with SEIS/EIS assurance done, I was ready to go. Or so I thought! I decided to focus on organic growth to prove the business. 3-years later I'm ready to go for the raise and FounderCatalyst kept their side of deal and have my funding round open and ready to go - no extra money required. Love these guys!!!”
