“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.”

“FounderCatalyst is not only a great platform but also a great community. I moved to FC after meeting founder Sam Simpson, and straightaway felt it was the right platform to support our needs - their service is fab, the fee structure is fair and transparent, and the platform is straightforward and easy to use. Sam himself is super engaged and responsive, and the FC WhatsApp group is a brilliant, collaborative and supportive community to be part of. Highly recommend!”

“A big thank you to the FounderCatalyst team for all their help, particularly in light of literally moments before submitting for our SEIS advance assurance, HMRC totally changed the submission format and method. Their team didn’t miss a beat and sorted everything. We received our confirmation of advance assurance in less than a week. Delighted is an understatement!”

“I wish I had met Sam earlier. I came across FounderCatalyst during a free webinar, Sam was so informative. This is my first funding round and Sam has made this process so easy. Help to understand the process, the rapid responses and attention to detail is excellent, even before I had committed. There was no time pressured 'special deal' deal on price, the pricing is really transparent and they do not take a percentage of your raise. The platform is easy to use and navigate, I have been able to invite my co-founder to the platform too. The templates and resources are also brilliant. Thank you Sam, I appreciate your support and we are excited for the journey ahead. Highly recommended.”

“I’ve completed two rounds with FounderCatalyst and have referred at least five fellow founders for their fundraising legal needs. The team is not only highly experienced and knowledgeable but also incredibly supportive, responsive, and fully understands the fast-paced nature of deal-making for founders. Their founder-first approach and service quality made me switch from Seedlegals to FounderCatalyst after my first round. Highly recommended.”
