Case study

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.”

A sample of testimonials from founders, advisors and investors who have worked with us.

“It was a pleasure working with FounderCatalyst. As of the first meeting, Sam was very involved in the whole process and made it very easy for us to get us investor ready faster than we could have ever imagined. We can only recommend the service and are about to use his services soon again.”

“We have a foreign company incorporated outside of the UK and thought that SEIS/EIS was impossible, but FounderCatalyst made the process straightforward and did the heavy lifting with the advance assurance application. Our potential investors from England now have full comfort that their investment in our company, despite it not being incorporated in the UK, will benefit from the full SEIS and EIS tax reliefs. Amazing!”

“Such a super-easy to use platform. Opened and closed a round and received the funds within 48-hours! Also, the business owner Sam is knowledgeable and supportive in other areas such as applications for SEIS/ EIS and the cost is lower than any other alternative - I checked!”

“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.”

“Our fundraising was anything BUT straightforward. Without the help from the team from FounderCatalyst, it very well might not have happened at all. There are other very good providers like this in the market, but none of them give the care and community that FC does. As the various wobbles and pitfalls came for us, it became clear we were in good hands. I not only recommend, I implore.”

“This platform helped more that i could have thought, from guiding me through my pre-seed raise, issuing the documents, keeping me accountable for what i needed to do...'You don't know what you don't know', and in a founder journey especially when dealing with legal and important paperwork this can fill you with fear. Luckily FC guides you through it all. Their community is also fab and so is their pricing.”

“FounderCatalyst's Agile functionality is perfect for navigating the messy reality of fundraising. It's incredibly simple to use, and takes the sting out of the otherwise intimidating paperwork. The FC team themselves are always going above and beyond - answering emails and lending a hand at awkward hours.”
