What founders say

In their words

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

“My initial funding round has involved a foreign investor with stringent compliance procedures - this has resulted in lots of back and forth. The FounderCatalyst team were absolutely amazing going above and beyond the support with platform and explanation of various documents. They were always available to hold our hand to support with all the requirements and the custom inputs required to ensure our documents complied with the needs of the foreign investor. This was really no easy feat!!! I cannot thank the FC team enough as well as the supportive FC community for getting us through this.”

“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.”

“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. ”
