And higher rated than competitors, according to Trustpilot.

“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 were initially recommended FounderCatalyst by an advisor to help us through our SEIS/EIS advanced assurance, and they have been nothing short of fantastic ever since. We ran our first fundraise through their platform, and will, without a doubt, use them again for future raises. As an early stage start-up founder I have leant on the team a lot and they have always been prompt (even at 11pm at night!), understanding & right on the money with their advice & support. Thank you FounderCatalyst!”

“Best decision we made as founders was switching to FounderCatalyst. Wasted a load of money with Seed Legals originally. Advice from some junior guys there vs Sam (a multiple exited founder and investor himself) doesn’t even compare. Sam had to spent a lot of time unpicking bad advice we had previously but did so with minimum fuss and no extra cost. Can’t recommend enough.”

“FounderCatalyst have been amazing, not only did they get the SEIS assurance as promised but the back up and additional services they provide as part of the service are invaluable. The community they create with other founders is also a great source of shared knowledge and support. Couldn’t recommend highly enough, thanks FC!”

“FounderCatalyst is simple to use, the price has no hidden extras or subscription mode, and is extremely good value. The back office support and advisors are exceptionally knowledgable and responsive. I have invested in over 45 Startups and had 3 of my own startups use the platform, and would recommend it to any founder or investor. If a founder is not happy with the level of legal documents for the cost then it is a big red flag that your money may not be spent on the most important things in the business. First rate product.”

“FounderCatalyst was introduced to me by a former colleague whilst I was exploring personal investment opportunities in companies already using the FC platform. After a briefing with Sam Simpson, I decided to use the platform for my own start-up Soul Padel. The S/EIS process couldn’t have been easier and simpler to understand and Sam’s hands-on guidance was much appreciated throughout. We then launched our SEIS round with FounderCatalyst and being a first time founder, it was enormously helpful to have the structured guides, articles and the hugely beneficial community of founders to tap into. Not only that but the ecosystem of professionals associated with the FC platform enabled me to seek cost effective advice early. We recently closed our first round after securing investment from a single HNW individual, without the use of costly lawyers or lengthy complex negotiations. I can’t recommend FounderCatalyst highly enough. If you are looking to start your own business and raise investment, you need to start your process with FounderCatalyst. It’s much much cheaper than what you’ll find elsewhere but the best thing is, Sam as founder will be your friend, guide and mentor throughout. Nowhere else gives you that level of service. It’s so good, I’ve also invested in FounderCatalyst platform users because I know their governance and structure is sound and very well put together. It’s more than just a service, it’s a community.”
