What's your current goal?

Secure SEIS/EIS relief

SEIS/EIS is one of the strongest incentives for your early-stage investors. We handle the advance assurance application fast, so you can close sooner.

Raise funds

You're raising funds, but the process is complex. Simplify it with expert guidance and SEIS/EIS support. You just focus on growing your business.

Motivate your team

EMI and unapproved share options align your team's goals with your mission, giving them real ownership and retaining talent to drive growth.

Protect your business

Legal documents are not only for companies raising funds. If you have an SME you still need legal documents to protect you and your business.

“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.”

In their words

A sample of testimonials from founders, advisors and investors who have worked with us.

“So far, so good. Have valued their responsiveness, advice and breadth of, no nonsense, step by step guides. They also helped us get SEIS/EIS pre assurance within 7 days. I wish I'd found them sooner.”

“Founders always need external, expert support, and never more so than in the area of handling HMRC and SEIS/EIS. This is where the big learning curves come from, and you don’t want to get this wrong - it follows you for a long time. The team at FounderCatalyst are wonderfully human, knowledgable, accessible, experienced and focus on helping the Founder - the human. ”

“Our fundraising was anything BUT straightforward. Without the help from the team from FounderCatalyst, it very well might not have happened at all. There are other very good providers like this in the market, but none of them give the care and community that FC does. As the various wobbles and pitfalls came for us, it became clear we were in good hands. I not only recommend, I implore.”

“If you are an early-stage start-up founder looking for legal services to close your round, PLEASE do not look anywhere else. We were working with a legal firm and reached nowhere in 2+ months. A mentor recommended FC and I was able to close the legals in 10 minutes (that claim on the website is indeed true)! The platform, cost and community of founders for getting quick support is AMAZING. And the FounderCatalyst team are approachable and very knowledgeable. Highly recommended.”

“FounderCatalyst has been fantastic - use this service!! We recently raised via CrowdCube and FounderCatalyst was very efficient at sorting out the legal paperwork, which removed all the stress from us. We are a new start-up and they made the legal processes of funding rounds incredibly easy to navigate. They sorted out our advance assurance in record speed. The team is incredibly knowledgeable (not only legal experts but exited founders) and they also have a great community on WhatsApp with other founders. ”

“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.”
