I'm a tech founder who is in Paris through a very similar program with Paris & Co, French Tech. If you have questions I'll loop back around to answer them based on my experience. Note: I didn't come with the French Tech Ticket (which was a different program that was more structured). I have an existing software company which I am expanding to France & Europe.
I had wanted to go and thought the company was a shoo-in since it was 100% bootstrapped and profitable at the time of application. Also growing like a weed. So I have no idea what they are doing, but they don't seem terribly competent and it was a waste of time to apply.
