Case study

£2.8M raised for just £1,450

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.

“Just closed my round on FounderCatalyst - super simple and having the FC team on hand for any question (even the silly ones) was brilliant. Fixed fee is a game changer vs the competition, allowing you to keep more of the funds you raise for getting going with your business.”

“I'm a technology lawyer by background so I test a lot of technology all the time and FounderCatalyst is very easy to use. When you're starting out, cash is tight, but their fixed fee gave us unlimited EMI and unapproved options, plus every vesting variation we needed - time based, conditional, exit only. I didn't think twice!”

“Blown away by the service and value: I was under pressure to close a funding round swiftly before the end of the tax year and the FC team were on point and held my hand right through the process. I’ve tried SeedLegals and the value we get from FounderCatalyst is way beyond - the support from FC is immediate and precise, compared with slow and inconsistent with SL.”

“We recently used FounderCatalyst to support our SEIS application, and the experience was exceptional from start to finish. Their communication was consistently clear, fast, and incredibly helpful — every question we had was answered promptly and with real expertise. The whole process felt streamlined and stress-free thanks to their guidance. I would happily recommend FounderCatalyst to anyone preparing an SEIS application. Their professionalism, responsiveness, and deep understanding of the process make them an outstanding partner for any startup navigating early-stage investment.”

“We incorporated in 2000 and started trading almost immediately. We recently started looking to expand our business into new territories and needed an equity investment to facilitate that. Unfortunately, attracting angel investment in the UK is very hard without offering SEIS or EIS. We thought the ship had sailed until FounderCatalyst mentioned a little-known EIS provision known as Condition B. Long story short, the FounderCatalyst team successfully secured EIS advance assurance and we are now raising using that scheme.”

“I approached my first funding round as a naive, first time founder with more to learn than I realised. From day 1, the FounderCatalyst team gave their time, knowledge and guidance in abundance. All I can say is that I thank my lucky stars that our paths crossed - I consider myself incredibly fortunate. With FounderCatalyst, you know they genuinely care about the success of the people they work with. They have made the HMRC AA process for SEIS a breeze. They has helped perfect our pitch deck, sanity check our financials and get our ducks in a row for our funding round, as well as give us that all important optimism when things get bumpy. The FounderCatalyst platform gives me and our investors complete confidence in arranging legals. Thank you!”

“FounderCatalyst were really responsive when we used them for our raise and always had clear guidance - even when we were asking them things that were clearly documented on their website :-). We chose them because their price was incredibly reasonable, and I'm glad to say the service exceeded our expectations at that price point.”
