“I had no idea about SEIS/EIS and the team clearly explained the process and took the hassle away by managing it end to end. They turned our deck and financial plan into an SEIS/EIS submission in less than a day and managed to get HMRC approval within two days enabling me to focus on my fundraise.”

“This was my first time raising funds and using SEIS, and FounderCatalyst made the process so much easier. They helped me secure Advance Assurance and were incredibly responsive and helpful throughout. Even though they have detailed articles on their site, they patiently answered all my basic questions. Their pricing is also excellent—just a one-time fee, which is great value. The service felt like an Amazon-level experience. I'm happy to say I’ve now raised my first round of funding, and I highly recommend FounderCatalyst to any first-time founder.”

“The process was incredibly easy, and it makes sense why this service exists for start-ups. I would highly recommend FounderCatalyst to anyone considering raising money and needing SEIS/EIS advanced assurance. Whilst it’s unnecessary because the platform is so slick and automated, Sam and the team are friendly and always available to help if investors have any questions. 10/10 service!!”

“As a first-time founder, the process of raising equity investment can seem like a complex puzzle. The FounderCatalyst platform has guided me through the process of generating investment documents, collecting signatures from investors, tracking funds and closing the round. When I needed that extra help solving the puzzle, the team were just an email away addressing queries with patience. Furthermore, they also simplified the mystical ritual of the S/EIS advance assurance application to make our investment opportunity shine even brighter. ”

“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. ”
