What founders say

In their words

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

“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. ”

“We’ve now used FounderCatalyst for 2 funding rounds as well as an EMI scheme, and they’ve been amazing throughout. We really value the simplicity, speed, customer support and transparent pricing. We needed an option scheme to incentivise employees under EMI. The Option service from FounderCatalyst is a total end to end package. It includes everything we needed; from defining the scheme, authorising the option pool, achieving EMI valuation approval with HMRC and inviting and issuing options to individuals. The process was slick and offered human support along the way…and was, at the time of our research, the most cost effective option too! ”

“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!”

“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!”

“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.”

“We met FounderCatalyst through the Startup 2 Standup Community, and were immediately impressed with their proactive approach to supporting founders. Their guidance from the very start with the advance assurance submission to closing our initial tranche has been truly invaluable, combined with the auto-documentation and flexibility the platform gives you at every stage in the round, makes FC the best choice for pre-seed startups.”
