FounderCatalyst delivered both - the process was seamless, and it cost less than a tenth of what I was quoted elsewhere. It let us stay focused on growing the business, not buried in fundraising admin.”

“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!”

“Having spoken with FounderCatalyst some 3-years ago, to get ready to raise with SEIS/EIS assurance done, I was ready to go. Or so I thought! I decided to focus on organic growth to prove the business. 3-years later I'm ready to go for the raise and FounderCatalyst kept their side of deal and have my funding round open and ready to go - no extra money required. Love these guys!!!”

“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!!”

“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!”

“I approached my first funding round as a naive, first time founder with more to learn than I realised. From day 1, the FounderCatalyst team gave their time, knowledge and guidance in abundance. All I can say is that I thank my lucky stars that our paths crossed - I consider myself incredibly fortunate. With FounderCatalyst, you know they genuinely care about the success of the people they work with. They have made the HMRC AA process for SEIS a breeze. They has helped perfect our pitch deck, sanity check our financials and get our ducks in a row for our funding round, as well as give us that all important optimism when things get bumpy. The FounderCatalyst platform gives me and our investors complete confidence in arranging legals. Thank you!”

“FounderCatalyst's Agile functionality is perfect for navigating the messy reality of fundraising. It's incredibly simple to use, and takes the sting out of the otherwise intimidating paperwork. The FC team themselves are always going above and beyond - answering emails and lending a hand at awkward hours.”
