“As a founder building an agentic AI platform for workforce planning in supply chains, I'm always looking for tools that save time and money. 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.”

“Getting through a funding round can be a stressful time but Sam, Max and the FounderCatalyst team were a constant source of advice, support and help. It means a lot when you know they’ve got your back. Having completed 2 previous rounds using a different approach, the FounderCatalyst route has been the best experience by a distance.”

“FounderCatalyst were really responsive when we used them for our raise and always had clear guidance - even when we were asking them things that were clearly documented on their website :-). We chose them because their price was incredibly reasonable, and I'm glad to say the service exceeded our expectations at that price point.”

“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!”

“I had a really important meeting with an investor and had realised my cap table needed adjusting since we had made a few changes in the last few months. We had been using another platform for our documentation, but unfortunately, time was of the essence, and I needed something I could send on ASAP, I needed help with it and unfortunately, this was not something they could provide. My first thought was of Sam. I have known Sam for the last few years whilst building Bezzelle and knew that he was someone who could potentially save the day, I can confirm not only brilliant with all things funding, also a super nice guy too! Awaiting the outcome of the investment meeting but he has a new customer for our next funding round! (Sorry in advance for all my share related queries!)”

“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.”
