What founders say

In their words

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

“We were unsure how to approach SEIS/EIS advance assurance, but FounderCatalyst made the process a breeze. Even better, we had a positive advance assurance confirmed by HMRC in less than five and a half hours! Crazy good. Sam and his team are incredibly knowledgable, clear, helpful and thorough. We could not recommend them more!”

“FounderCatalyst could not have been more helpful and supportive throughout our SEIS process.They worked diligently to help us get advance assurance much faster than we thought was possible. They went above and beyond the basic advance assurance process, and played a crucial role in helping us to secure funding. I can not recommend FounderCatalyst enough.”

“Just closed my round on FounderCatalyst - super simple and having the FC team on hand for any question (even the silly ones) was brilliant. Fixed fee is a game changer vs the competition, allowing you to keep more of the funds you raise for getting going with your business.”

““A Lifesaver for First-Time Founders! As a first-time founder raising funds for the first time, I was overwhelmed by the complexity of documents like the SH01 and EIS3. Founder Catalyst made the entire process so much easier. Sam was incredibly helpful and always accessible, whether via video calls, direct messages, or through the Founder Catalyst WhatsApp group, which is filled with a supportive and knowledgeable founder community.””

“FounderCatalyst have been excellent from start to finish. SEIS/EIS advance assurance support at a fixed rate and with lots of support. The best bit is the ongoing community of support- wouldn't go anywhere else and we'll be engaging in the new products/services which Sam & the Team bring out this year.”
