Getting into YC changed the course of the company, increased many orders of magnitude my ambition and made fundraising much easier. Most importantly, even though I worked in tech in the bay many moons ago, at the time I was very isolated in Paris and thought I understood the startup game but I did not really. Being part of a cohort like YC with like-minded amazing peers, truly felt like I was able to go up to speed on many subjects that would have been out of reach for a solo founder.
If you are a solo technical founder and considering applying to YC, reach out to me, I am more than happy to help.
