“As a founder building an agentic AI platform for workforce planning in supply chains, I'm always looking for tools that save time and money. 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.”

What founders say

In their words

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

“FounderCatalyst was incredible to work with from start-to-end for our pre-seed round. They were meticulous, prompt to reply, and handled numerous customisations. I've used other legal services and platforms which came up too expensive and prone to errors. FounderCatalyst is miles ahead in terms of service, value-for-money and legal expertise.”

“They say word-of-mouth is the best kind of marketing, and judging by the people who pop up in every entrepreneur group singing FounderCatalyst’s praises (myself included!), they are smashing it! As first-time founders, there was so much we were nervous about or didn’t fully understand, and FounderCatalyst has consistently made time for us and never laughed at our questions! The founder Sam truly goes above and beyond to share relevant contacts and opportunities for his founders. They handled our entire fundraising journey perfectly and I couldn't have asked for a better partner. Highly recommend.”

“We were unsure how to approach SEIS/EIS advance assurance, but FounderCatalyst made the process a breeze. Even better, we had a positive advance assurance confirmed by HMRC in less than five and a half hours! Crazy good. Sam and his team are incredibly knowledgable, clear, helpful and thorough. We could not recommend them more!”

“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.”

“I used FounderCatalyst to assist with my advance assurance as my situation was unusual. FounderCatalyst built my advance assurance submission for me to save me learning the process, I reviewed and submitted on the 19th of September 2024. I was elated to receive confirmation of advance assurance the very next day.”

“FounderCatalyst made it simple for me to apply for HMRC SEIS Advance Assurance and set up my funding round. Using helpful templates provided by FounderCatalyst, I spent a few weeks refining my pitch deck and forecast. Once I was ready, it took less than an hour to get everything online and submitted to HMRC. I hit submit at 11am on a Thursday and by 9am the following Monday, I had the good news from HMRC!”

“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.”
