“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.”

“FoundersCatalyst has been second to none in supporting our raise, with Sam and the team offering invaluable guidance to ensure a seamless round for us and our investors.

“Sam and the FounderCatalyst are attentive, diligent and extremely helpful with all things associated with a funding round, particularly, when it comes to legals. Sam has built a supportive and thriving community and that's a testament to his founder-first approach. I'd highly recommend his services to any founder looking to raise investment.”

“The FounderCatalyst platform helped us close our round in hours rather than weeks and they were so hands on and helpful all the way through the process. We were an early adopter of their SEIS1 compliance to SEIS3 certificate process and our investors received their forms in less than 2 weeks, and also commented on how ‘seamless’ the process was. Will definitely be using FounderCatalyst again!”

“I had little knowledge of the legal processes of raising investment. Our CCO recommended FounderCatalyst and we have both been very glad we chose this route. The FounderCatalyst team led us through the system personally and the online portal, including electronic document signing, was fantastic.”

“I've got a background in law, so I'm comfortable with the mechanics of a funding round. The FounderCatalyst service is unique though - they give you personal support and use their experience to guide you through the key decisions - something only exited founders and angels investors can provide.”
