“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.”

“We have used FounderCatalyst to close two funding rounds, their whole team has been incredibly helpful. The SEIS advance assurance process was incredibly slick and the funding dashboard makes it easy to track which documents investors have signed. Their customer service has been unmatched with support every step of the way to answer any questions. Finally, our raise cost less than a 3rd of the price of their competition - amazing value!”

“I approached my first funding round as a naive, first time founder with more to learn than I realised. From day 1, the FounderCatalyst team gave their time, knowledge and guidance in abundance. All I can say is that I thank my lucky stars that our paths crossed - I consider myself incredibly fortunate. With FounderCatalyst, you know they genuinely care about the success of the people they work with. They have made the HMRC AA process for SEIS a breeze. They has helped perfect our pitch deck, sanity check our financials and get our ducks in a row for our funding round, as well as give us that all important optimism when things get bumpy. The FounderCatalyst platform gives me and our investors complete confidence in arranging legals. Thank you!”

“I sent FounderCatalyst my pitch deck and forecast model. They gave me feedback and then prepared a pack to submit to HMRC for EIS advance assurance. I was amazed that HMRC responded with confirmation of advance assurance before 9:15 the next working day!”

“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!)”
