What founders say

In their words

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

“FounderCatalyst is truly a Founder friendly company, both when things go well and unexpectedly. I was dealing with quite an outlier situation with my company. Max, Sam and team did their absolute best to help resolve the situation. I was impressed with their responsiveness and knowledge. There are alternative legal platforms out there, but none that truly holds founder friendliness as a core principle. Highly highly recommend.”

“FounderCatalyst helped with a set of 13x individual queries from HMRC on a advance assurance submission we originally completed ourselves. They wrote a professional response letter answering the queries and HMRC replied with confirmation of advance assurance in just a few hours.”

“Working with FounderCatalyst was great! This was my first fundraising round, and the whole experience was made super straightforward. Sam always seemed to be on hand to answer any questions we had, which was a huge help throughout - including providing recommendations for related services such as accounting and legal counsel. Would definitely recommend!”

“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.”
