“We started our new company under our old company. Rookie mistake. This meant we fell outside of the timeline for EIS by more than a few years. FounderCatalyst worked with us on an appeal. Our new company was different to our old one. We had invested into it's development and were turning revenue. We got the thumbs up from HMRC. Was a happy day.”

“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!”
