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 just raised our first seed round and quite frankly couldn’t have done it without FounderCatalyst. Sam Simpson is the kindest most patient founder I have ever met. The website is so easy to use (and even if you have a question it’s answered in minutes). A very reasonably priced service that I would highly recommend to anyone looking to raise.”

“Sam and the team at FounderCatalyst go above and beyond to aid founders through the SEIS process to accreditation. Unlike their competitors, they charge a fixed fee, no recurring fee, and offer a tremendous peer-to-peer community, which has been invaluable in helping me build my team. It is time for change. Step away from household brands and try FounderCatalyst.”

“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.”

“We used another provider for our SEIS/EIS advance approval application but, because our TopCo is overseas and we have a touchpoint with digital assets, HMRC had some queries that our provider was not able to advise on. Sam/FounderCatalyst gave quick and valuable support with our responses.”

“Thank you to FounderCatalyst for making Investment easy and guiding us through all the legal steps required and answering all our queries so quickly. If you are a founder looking for SEIS and EIS approval, looking to understand where to find investors, or simply need support with the legal side of investment FounderCatalyst are the team to talk too.”

“I consider myself fortunate to be introduced to FounderCatalyst prior to our fundraise in October 2022. Having never raised funds before, working with FounderCatalyst was a perfect fit, the in-house expertise on SEIS/EIS was worth the fee alone coupled with the excellent easy-to-use platform and on-tap advice was great. In addition, a 'bonus' feature is being part of the FounderCatalyst group on WhatsApp which is a thriving community of fellow founders that share knowledge, experience, and general advice. A great platform, a great team, and a great community, highly recommended.”

“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.”

“Our EIS time limit had expired and were looking for funding outside the EIS scheme. FounderCatalyst were really interested in the challenge and it was clear from our early conversations that they knew the intricacies of the various options. They identified KIC as a potential alternative for us and provided clear instructions and hands-on support with our KIC advance assurance submission. We received advance assurance within two weeks of our submission. I have no hesitation in recommending them to others.”

“We were referred to FounderCatalyst and told that they were good, but our advance assurance submission received a positive response from HMRC in 25 hours – that is better than good!”
