“As a founder building an agentic AI platform for workforce planning in supply chains, I'm always looking for tools that save time and money. FounderCatalyst delivered both - the process was seamless, and it cost less than a tenth of what I was quoted elsewhere. It let us stay focused on growing the business, not buried in fundraising admin.”

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 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.”

“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 made it simple for me to apply for HMRC SEIS Advance Assurance and set up my funding round. Using helpful templates provided by FounderCatalyst, I spent a few weeks refining my pitch deck and forecast. Once I was ready, it took less than an hour to get everything online and submitted to HMRC. I hit submit at 11am on a Thursday and by 9am the following Monday, I had the good news from HMRC!”
