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.
Applied to the program with my last company. There was no response and no interview other than a rejection email. The business is now running millions in orders and several hundred thousands a year in revenue.
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.
Props on growing your business. Mine is also bootstrapped and doing well. Sorry that was your experience. They so seem to have particular types of businesses they are more interested in (though I don't know what that criteria is).
