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.”

“I’ve been told by another founder that SEIS / EIS advance assurance could take months – FounderCatalyst submitted our advance assurance on the 3rd of October 2023 and we received a positive response in just 24 hours”

“We’ve now used FounderCatalyst for 2 funding rounds as well as an EMI scheme, and they’ve been amazing throughout. We really value the simplicity, speed, customer support and transparent pricing. We needed an option scheme to incentivise employees under EMI. The Option service from FounderCatalyst is a total end to end package. It includes everything we needed; from defining the scheme, authorising the option pool, achieving EMI valuation approval with HMRC and inviting and issuing options to individuals. The process was slick and offered human support along the way…and was, at the time of our research, the most cost effective option too! ”

“We used FounderCatalyst to do our SEIS advance assurance, our initial fundraising round, and subsequent agile round. The experience throughout all this was incredible. The level of personal service and attention to detail is unmatched. I have previously used a competitor service and it doesn't come close to what FounderCatalyst offers. We will continue using them and cannot recommend Sam and the team highly enough.”
