French here, not in a startup but in an international company. Meetings are in english as soon a non french speaker is there, but during lunch, discussions are often in french even when non french speaker are present. I know it is not very polite. I really think you must learn french if you come to work in France. Even if your french is totally broken, the effort to speak french will be really appreciated. I have some coworkers who can speak french quite well but asked me to not tell it at work so that they can continue to prented they can't. This is also a reasonnable choice. I think you need to have a good understanding of oral french. People won't care if you make mistakes or if you write mails in english.

I have noticed that OpenOffice (or LibreOffice) is far less popular here than in US. I think that IOS and linux are also slightly less popular than in US.
