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.”

“We were initially recommended FounderCatalyst by an advisor to help us through our SEIS/EIS advanced assurance, and they have been nothing short of fantastic ever since. We ran our first fundraise through their platform, and will, without a doubt, use them again for future raises. As an early stage start-up founder I have leant on the team a lot and they have always been prompt (even at 11pm at night!), understanding & right on the money with their advice & support. Thank you FounderCatalyst!”

“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!”

“We signed up to FC following a recommendation from several founders I met through startup networks. You and your documents are in safe hands - the real bonus is being able to ask loads of questions and get support on so many random things that aren't directly documentation but necessary for a raise (eg how do you write a valuation document, what do you include in your data room, disclosure). You can ask these both from FC and the FC founder community.”
