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.”

“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!”

“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.”

“If you want speed, service and cost efficiency. FC are your guys. - Wow! FC is another level of good. From my first intro call with Sam (he was keen to explain and simplify the process for us) to concluding investment and issuing the SEIS3 certificates to investors, the process has been so intuitive and efficient....and speedy! The human response time on their support is remarkable. I used the 'other' guys for years and this is a whole different experience...and MUCH cheaper. Bravo.”
