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.”

“FounderCatalyst is the best platform on the market to help early-stage founders with their fundraising legals. Not only is the platform fantastic, the team, especially Sam, have been absolutely instrumental in helping us close our recent funding round. I can honestly say that without FounderCatalyst and Sam by our side, we wouldn't have been able to succeed in our fundraising efforts.”

“The FounderCatalyst platform helped us close our round in hours rather than weeks and they were so hands on and helpful all the way through the process. We were an early adopter of their SEIS1 compliance to SEIS3 certificate process and our investors received their forms in less than 2 weeks, and also commented on how ‘seamless’ the process was. Will definitely be using FounderCatalyst again!”

“They say word-of-mouth is the best kind of marketing, and judging by the people who pop up in every entrepreneur group singing FounderCatalyst’s praises (myself included!), they are smashing it! As first-time founders, there was so much we were nervous about or didn’t fully understand, and FounderCatalyst has consistently made time for us and never laughed at our questions! The founder Sam truly goes above and beyond to share relevant contacts and opportunities for his founders. They handled our entire fundraising journey perfectly and I couldn't have asked for a better partner. Highly recommend.”

“We completed our first raise with FC and the process was simple, effective and a bargain. They combine excellent advice and an extremely responsive support team, which is so important as even though the process is clear and well explained, you do not want to make mistakes! Emma from their team has been amazing, helping me get in a time sensitive submission ahead of the tax deadline, including helping me on a Saturday in Twixtmas! Thank you very much!”
