Do you mean valid as in there are no NY startups at or above that valuation? There are definitely some NY based startups above the $5b mark, though the ones I know of are B2B, not B2C.

Who? Oscar is the biggest one I can think of, and they're <$3b.

I'd also bet on at least two of these being >$50b within 3y. {Uber, Lyft, Airbnb, Didi, Meuitan, Ola, Flipkart, Snapchat} (Uber already is, so it's really "a second one")

Dataminr at $10b.

Ah! Thanks -- I had them mentally filed as DC/NoVA because I know about them only from Government stuff.

Oh, WeWork. But I think that's the only one.
