What founders say

In their words

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

“FounderCatalyst was recommended to us by a trusted friend to help with our SEIS/EIS advance assurance before we opened our first investment round - and this was done at speed driven by the expertise of their team. The platform and team provided all the core information, legal documents and support needed to work with investors and the digital platform for investors to engage - and as a new startup this has been essential and has removed a lot of stress and worry in an area of the business new to us. Throughout the fundraising, FounderCatalyst has been there with endless support. I would fully recommend the FounderCatalyst service as a core part of your fundraising plans and process.”

“If you are an early-stage start-up founder looking for legal services to close your round, PLEASE do not look anywhere else. We were working with a legal firm and reached nowhere in 2+ months. A mentor recommended FC and I was able to close the legals in 10 minutes (that claim on the website is indeed true)! The platform, cost and community of founders for getting quick support is AMAZING. And the FounderCatalyst team are approachable and very knowledgeable. Highly recommended.”

“Having spoken with FounderCatalyst some 3-years ago, to get ready to raise with SEIS/EIS assurance done, I was ready to go. Or so I thought! I decided to focus on organic growth to prove the business. 3-years later I'm ready to go for the raise and FounderCatalyst kept their side of deal and have my funding round open and ready to go - no extra money required. Love these guys!!!”

“We have a foreign company incorporated outside of the UK and thought that SEIS/EIS was impossible, but FounderCatalyst made the process straightforward and did the heavy lifting with the advance assurance application. Our potential investors from England now have full comfort that their investment in our company, despite it not being incorporated in the UK, will benefit from the full SEIS and EIS tax reliefs. Amazing!”
