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.”

“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.”

“Prior to working with FounderCatalyst, we had conducted the legalities of our first funding round via accountants and lawyers and found a real disconnect between the two. We reached out to FounderCatalyst for round 2 and couldn’t be happier with the service. They are on hand to personally deal with any requests or questions - there is a real accountability of the full process and depth of knowledge that you’re able to leverage. We would not go elsewhere for another round.”

“FounderCatalyst is more than just a digital fundraising platform—it's a true game changer for entrepreneurs. From day one, the level of support we received was unmatched. The team is practically on call 24/7, ready to answer every question we had, and they didn’t just give us answers—they took the time to explain the entire process in detail. This personal touch is worth its weight in gold. One of the standout features is the community. It’s filled with experts, successful ex-founders, investors, and fellow entrepreneurs, all actively engaged in fundraising. And when I say active, I mean good active—it's a highly useful, focused community with zero fluff or random chatter. Every discussion is purposeful, providing real value to your fundraising journey. FounderCatalyst helped us secure an ASA within weeks and managed all of HMRC’s queries seamlessly. The platform made the entire process so much smoother than I ever imagined. If you're looking for a platform that combines cutting-edge technology with real human expertise and support, look no further than FounderCatalyst. It's been absolutely pivotal in our fundraising success!”

“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.”
