“From clicking submit on our SEIS & EIS advance assurance 3rd June 2024 to a thumbs up from HMRC in less than 24 hours is wild. Thanks FounderCatalyst!”

“Seven weeks ago, I had no clue what Seis/EIS INVESTMENT WAS! as a solo founder I’ve been finding my way on the rollercoaster of building a business front scratch. I had signed up with a competitor 2 weeks before I found myself on a webinar with Sam Simpson from Founder Catalyst. As an exited founder and current investor, Sam set up Founders Catalyst to support entrepreneurs to understand, prepare for and then secure investment. What struck me about the webinar was that I understood everything he said - it finally made sense. I immediately cancelled my existing agreement (having felt totally overwhelmed and unsupported once they had their fee) and moved to Founders Catalyst. Today I closed my first round of investment- 5 weeks since I attended the webinar! Shout out to Sam (has walked the walk and gives his time and expertise generously), Emma (for walking me through the setting up process) Max (so patient! And knowledgeable). Oh, and when you send a support message, a human messages you back, quickly! I’ll now embark on the confirmation paperwork (investment is a journey) but taking a minute to show true appreciation for a business that delivers.”

“Blown away by the service and value: I was under pressure to close a funding round swiftly before the end of the tax year and the FC team were on point and held my hand right through the process. I’ve tried SeedLegals and the value we get from FounderCatalyst is way beyond - the support from FC is immediate and precise, compared with slow and inconsistent with SL.”

“A big thank you to the FounderCatalyst team for all their help, particularly in light of literally moments before submitting for our SEIS advance assurance, HMRC totally changed the submission format and method. Their team didn’t miss a beat and sorted everything. We received our confirmation of advance assurance in less than a week. Delighted is an understatement!”
