What founders say

In their words

A sample of testimonials from founders, advisors and investors who have worked with us.

“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.”

“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.”

“We founded Giles AI to dramatically accelerate clinical and medical research using secure, cutting-edge, conversational AI. The impact is transformative: a typical 10-year, $1.5bn drug or device development pipeline can be accelerated significantly – getting life-saving innovations to market faster than ever before. With our collaboration with Google, our recent £750K pre-seed raise gives us the runway to scale rapidly - FounderCatalyst were instrumental facilitating the raise, providing expert legal guidance and an incredibly efficient process that let us stay focused on building the future of medical research.”

“FounderCatalyst has been absolutely superb in helping me navigate the SEIS/EIS advance assurance process. My business certainly was not vanilla in its application process, but they took the time to brainstorm the best way to conduct our application. The team always act in a very timely manner, with a knowledgeable understanding of the process. Certainly would recommend the FounderCatalyst to any start-up!”

“Sam and team provide a faultless service. I've been incredibly impressed with the rapid response time of any questions I send, and the level of detail and reassurance provided to make sure we fully understand the process. We flew through the HMRC (S)EIS Advance Assurance process: submitting it just before 5pm on a Monday, and having received confirmation of it by 1:30pm the next day! Can't get much better than that. Really very happy to have chosen FounderCatalyst.”

“We met FounderCatalyst through the Startup 2 Standup Community, and were immediately impressed with their proactive approach to supporting founders. Their guidance from the very start with the advance assurance submission to closing our initial tranche has been truly invaluable, combined with the auto-documentation and flexibility the platform gives you at every stage in the round, makes FC the best choice for pre-seed startups.”
