Was that the Silicon Beach mixer at Areal? My girlfriend (in entertainment law) somehow ended up there and I didn't (because I was probably at home coding).
I haven't seen this announced anywhere, but there's some building permits plastered on a window at the corner of Pico and Main indicating that Santa Monica is about to get a Twitter office.
There's an interesting cluster of Bitcoin businesses (GoCoin, ExpressCoin, others) with office space right over the Santa Monica Promenade and another Bitcoin exchange (CoinMrkt) in the neighborhood. It feels like things are ramping up around here.
