And higher rated than competitors, according to Trustpilot.

“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.

“Best decision we made as founders was switching to FounderCatalyst. Wasted a load of money with Seed Legals originally. Advice from some junior guys there vs Sam (a multiple exited founder and investor himself) doesn’t even compare. Sam had to spent a lot of time unpicking bad advice we had previously but did so with minimum fuss and no extra cost. Can’t recommend enough.”

“The FounderCatalyst team turned my advance assurance application around in just 2 working days and we had a positive response back from HMRC within a week. Their assistance with preparing my Investors Deck and forecast model was invaluable. We highly recommend using FounderCatalyst to other founders!”

“I’ve completed two rounds with FounderCatalyst and have referred at least five fellow founders for their fundraising legal needs. The team is not only highly experienced and knowledgeable but also incredibly supportive, responsive, and fully understands the fast-paced nature of deal-making for founders. Their founder-first approach and service quality made me switch from Seedlegals to FounderCatalyst after my first round. Highly recommended.”

“We’ve now used FounderCatalyst for 2 funding rounds as well as an EMI scheme, and they’ve been amazing throughout. We really value the simplicity, speed, customer support and transparent pricing. We needed an option scheme to incentivise employees under EMI. The Option service from FounderCatalyst is a total end to end package. It includes everything we needed; from defining the scheme, authorising the option pool, achieving EMI valuation approval with HMRC and inviting and issuing options to individuals. The process was slick and offered human support along the way…and was, at the time of our research, the most cost effective option too! ”

“FounderCatalyst was incredible to work with from start-to-end for our pre-seed round. They were meticulous, prompt to reply, and handled numerous customisations. I've used other legal services and platforms which came up too expensive and prone to errors. FounderCatalyst is miles ahead in terms of service, value-for-money and legal expertise.”

“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.”

“FounderCatalyst has been fantastic - use this service!! We recently raised via CrowdCube and FounderCatalyst was very efficient at sorting out the legal paperwork, which removed all the stress from us. We are a new start-up and they made the legal processes of funding rounds incredibly easy to navigate. They sorted out our advance assurance in record speed. The team is incredibly knowledgeable (not only legal experts but exited founders) and they also have a great community on WhatsApp with other founders. ”
