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.

“I turned to Sam at FounderCatalyst after being misguided by his competitors about eligibility for SEIS as an investor. I have spent three weeks emailing HMRC and my legal team and could not get a straight answer. Sam gave me a definitive explanation the following day. From now on I will be using FounderCatalyst for all my equity funding legal needs!”

“I've got a background in law, so I'm comfortable with the mechanics of a funding round. The FounderCatalyst service is unique though - they give you personal support and use their experience to guide you through the key decisions - something only exited founders and angels investors can provide.”

“Our experience using FounderCatalyst was quick and easy. FounderCatalyst have turned the onerous task of raising funds into an easy process for not only ourselves, but our investors too. I would recommend FC to anyone raising their seed round.”

“I had a fantastic experience with FoundersCatalyst from start to finish (and continue to receive ongoing support). They responded quickly to my initial inquiry, providing excellent guides and transparent information about fees, how the platform works, and what to expect. After following their templates and guidance, we submitted our pitch deck and financial forecast, and Founders Catalyst handled our SEIS application to HMRC. We received approval within three weeks, with no complications. The platform is straightforward to set up, offering term sheets, a data room etc., and a wealth of video/blog content to help. For specific inquiries, their ticketing system is incredibly responsive—usually within a few hours. On top of that, there’s an excellent community on WhatsApp, which includes all the FC staff as well as peers who are friendly, welcoming, and happy to answer even our "stupid questions" throughout the entire funding journey. I can't recommend FoundersCatalyst enough. The founder, Sam, is exceptionally knowledgeable and very generous with his time, supporting every founder to succeed in their funding rounds.”

“It was a pleasure working with FounderCatalyst. As of the first meeting, Sam was very involved in the whole process and made it very easy for us to get us investor ready faster than we could have ever imagined. We can only recommend the service and are about to use his services soon again.”

“I'm a technology lawyer by background so I test a lot of technology all the time and FounderCatalyst is very easy to use. When you're starting out, cash is tight, but their fixed fee gave us unlimited EMI and unapproved options, plus every vesting variation we needed - time based, conditional, exit only. I didn't think twice!”

“As a solo-founder and 'start-up newbie', the service, support, specialism and community that FounderCatalyst offers is invaluable. From formal paperwork completion to the 'Friendly Founders' WhatsApp chat, I just wish that I had joined sooner...”
