In their words

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

“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!”

“FounderCatalyst have been excellent from start to finish. SEIS/EIS advance assurance support at a fixed rate and with lots of support. The best bit is the ongoing community of support- wouldn't go anywhere else and we'll be engaging in the new products/services which Sam & the Team bring out this year.”

“FounderCatalyst have been amazing, not only did they get the SEIS assurance as promised but the back up and additional services they provide as part of the service are invaluable.

“FounderCatalyst has been absolutely superb in helping me navigate the SEIS/EIS advance assurance process. My business certainly was not vanilla in its application process, but they took the time to brainstorm the best way to conduct our application. The team always act in a very timely manner, with a knowledgeable understanding of the process. Certainly would recommend the FounderCatalyst to any start-up!”

“We started our new company under our old company. Rookie mistake. This meant we fell outside of the timeline for EIS by more than a few years. FounderCatalyst worked with us on an appeal. Our new company was different to our old one. We had invested into it's development and were turning revenue. We got the thumbs up from HMRC. Was a happy day.”
