Where did you get the idea that there is no French tech alumni network in Silicon Valley? There are plenty of meetings of French tech professionals. DBF is the one running the longest. The French chamber of commerce also organizes a lot of thematic events.<p>We even have a few "Grandes Ecoles" based events, which tend to do poorly.
I'm very surprised this didn't exist already as most places I've worked have had a number of French nationals.<p>How strict is the French national or degree granted from French uni rule? I know a few who are in tech and bilingual but degrees were granted in the US.
