What founders say

In their words

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

“I’m so glad I was introduced to FounderCatalyst. They are the absolute go-to team for SEIS Assurance and fundraising legal paperwork. Their advice is succinct, and any questions are answered quickly, usually within an hour which is incredible service. The FounderCatalyst community is super supportive. I’ve seen it grow tenfold in less than 12 months, I guess that says it all…”

“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.”

“We have used FounderCatalyst to close two funding rounds, their whole team has been incredibly helpful. The SEIS advance assurance process was incredibly slick and the funding dashboard makes it easy to track which documents investors have signed. Their customer service has been unmatched with support every step of the way to answer any questions. Finally, our raise cost less than a 3rd of the price of their competition - amazing value!”

“We raised £304,000 on the FounderCatalyst platform and that gave us the confidence to use their option scheme service. We shopped around competitors but the fact we could have unlimited EMI options for staff and unlimited unapproved options for advisors was an amazing opportunity, with zero scaling costs.”
