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.

“I switched from SeedLegals to FounderCatalyst which has proved both cheaper and the customer service is infinitely better. Everything is included in the one off fee so you aren't hit by extra fees you don't expect. The team includes ex founders and investors so you get both technical and tactical support, which wasn't the case with SeedLegals. I also get very rapid responses to my emails, which was a refreshing change. ”

“We used FounderCatalyst to do our SEIS advance assurance, our initial fundraising round, and subsequent agile round. The experience throughout all this was incredible. The level of personal service and attention to detail is unmatched. I have previously used a competitor service and it doesn't come close to what FounderCatalyst offers. We will continue using them and cannot recommend Sam and the team highly enough.”

“Sam and team provide a faultless service. I've been incredibly impressed with the rapid response time of any questions I send, and the level of detail and reassurance provided to make sure we fully understand the process. We flew through the HMRC (S)EIS Advance Assurance process: submitting it just before 5pm on a Monday, and having received confirmation of it by 1:30pm the next day! Can't get much better than that. Really very happy to have chosen FounderCatalyst.”

“Founders always need external, expert support, and never more so than in the area of handling HMRC and SEIS/EIS. This is where the big learning curves come from, and you don’t want to get this wrong - it follows you for a long time. The team at FounderCatalyst are wonderfully human, knowledgable, accessible, experienced and focus on helping the Founder - the human. ”

“The level of service you receive is not in line with how much you pay. Typical SaaS businesses will take your payment and offer no support but I would argue you receive a lot more support and service than you pay for. Sam is a wealth of knowledge as well”

“We were unsure how to approach SEIS/EIS advance assurance, but FounderCatalyst made the process a breeze. Even better, we had a positive advance assurance confirmed by HMRC in less than five and a half hours! Crazy good. Sam and his team are incredibly knowledgable, clear, helpful and thorough. We could not recommend them more!”
