What founders say

In their words

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

“I’d heard that FounderCatalyst’s SEIS advance assurance was lightning quick from another founder, but they’ve excelled themselves with Archive This Ltd. Full advance assurance received from HMRC in less than 3 working hours.”

“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.”

“FounderCatalyst has proved an outstanding solution for our fundraising efforts. Being new to the entrepreneur world and indeed that of raising investment, the FounderCatalyst platform takes all the headaches (and cost) out of the legal and admin side of the raise, so I could focus on communicating with our investors. The support received from the team was second to none and the instant build paperwork and cap table forecasting made the whole process incredibly organised and clear. While I may not be a fundraising novice anymore, I wouldn't hesitate to use FounderCatalyst again when the time comes for a future investment round.”
