What founders say

In their words

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

“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.”

“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.”
