£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.

“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!”

“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.”

“I sent FounderCatalyst my pitch deck and forecast model. They gave me feedback and then prepared a pack to submit to HMRC for EIS advance assurance. I was amazed that HMRC responded with confirmation of advance assurance before 9:15 the next working day!”

“I've got a background in law, so I'm comfortable with the mechanics of a funding round. The FounderCatalyst service is unique though - they give you personal support and use their experience to guide you through the key decisions - something only exited founders and angels investors can provide.”

“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”
