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.”

“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.”

“Sam and team provide a faultless service. I've been incredibly impressed with the rapid response time of any questions I send, and the level of detail and reassurance provided to make sure we fully understand the process. We flew through the HMRC (S)EIS Advance Assurance process: submitting it just before 5pm on a Monday, and having received confirmation of it by 1:30pm the next day! Can't get much better than that. Really very happy to have chosen FounderCatalyst.”

“We have a foreign company incorporated outside of the UK and thought that SEIS/EIS was impossible, but FounderCatalyst made the process straightforward and did the heavy lifting with the advance assurance application. Our potential investors from England now have full comfort that their investment in our company, despite it not being incorporated in the UK, will benefit from the full SEIS and EIS tax reliefs. Amazing!”

“This is the first time we have raised investment for Trove. It can be daunting to keep on top of all of the requirements and documentation. We are so happy to have the support of FounderCatalyst - their technology is user friendly for both founders and investors. Moreover the team are so responsive in supporting any questions. It is clear they understand founder needs having been successful entrepreneurs themselves. We would highly recommend FounderCatalyst and look forward to working together on future funding rounds.”
