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.

“The team went above and beyond to ensure our application received SEIS and EIS assurance. They worked very quickly, were always responsive to emails and seemed to work all hours of the days to get it done! When HMRC came back with some questions they helped to answer them in the correct way”

“If you want speed, service and cost efficiency. FC are your guys. - Wow! FC is another level of good. From my first intro call with Sam (he was keen to explain and simplify the process for us) to concluding investment and issuing the SEIS3 certificates to investors, the process has been so intuitive and efficient....and speedy! The human response time on their support is remarkable. I used the 'other' guys for years and this is a whole different experience...and MUCH cheaper. Bravo.”

“This was my first time raising funds and using SEIS, and FounderCatalyst made the process so much easier. They helped me secure Advance Assurance and were incredibly responsive and helpful throughout. Even though they have detailed articles on their site, they patiently answered all my basic questions. Their pricing is also excellent—just a one-time fee, which is great value. The service felt like an Amazon-level experience. I'm happy to say I’ve now raised my first round of funding, and I highly recommend FounderCatalyst to any first-time founder.”
