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.

“They say word-of-mouth is the best kind of marketing, and judging by the people who pop up in every entrepreneur group singing FounderCatalyst’s praises (myself included!), they are smashing it! As first-time founders, there was so much we were nervous about or didn’t fully understand, and FounderCatalyst has consistently made time for us and never laughed at our questions! The founder Sam truly goes above and beyond to share relevant contacts and opportunities for his founders. They handled our entire fundraising journey perfectly and I couldn't have asked for a better partner. Highly recommend.”

“FounderCatalyst could not have been more helpful and supportive throughout our SEIS process.They worked diligently to help us get advance assurance much faster than we thought was possible. They went above and beyond the basic advance assurance process, and played a crucial role in helping us to secure funding. I can not recommend FounderCatalyst enough.”

“We raised £304,000 on the FounderCatalyst platform and that gave us the confidence to use their option scheme service. We shopped around competitors but the fact we could have unlimited EMI options for staff and unlimited unapproved options for advisors was an amazing opportunity, with zero scaling costs.”

“Swift is an understatement: I joined the FounderCatalyst platform at 5pm and 4 hours later my pitch deck & forecast had been reviewed and my SEIS advance assurance was with HMRC.”

“Best decision we made as founders was switching to FounderCatalyst. Wasted a load of money with Seed Legals originally. Advice from some junior guys there vs Sam (a multiple exited founder and investor himself) doesn’t even compare. Sam had to spent a lot of time unpicking bad advice we had previously but did so with minimum fuss and no extra cost. Can’t recommend enough.”

“My initial funding round has involved a foreign investor with stringent compliance procedures - this has resulted in lots of back and forth. The FounderCatalyst team were absolutely amazing going above and beyond the support with platform and explanation of various documents. They were always available to hold our hand to support with all the requirements and the custom inputs required to ensure our documents complied with the needs of the foreign investor. This was really no easy feat!!! I cannot thank the FC team enough as well as the supportive FC community for getting us through this.”
