Former Twitter CEO Dick Costolo and former Twitter COO Adam Bain have launched a San Francisco-based startup advisory and investment firm called 01 Advisors, Axios has learned from multiple sources.

The bottom line: Costolo and Bain have been angel investing and advising together for the past couple of years, including in companies like TripActions, but are now formalizing their efforts.

01 Advisors is also raising a fund so that it can get equity beyond "advisory shares." In this way, it's a bit similar to how Tusk Ventures, led by former Uber and Michael Bloomberg campaign adviser Bradley Tusk, operates.
Former Twitter investor relations executive David Rivinus is also involved, in addition to Costolo and Bain.

Update: After this story was published, 01 Advisors disclosed in an SEC filing that it has secured $135 million for a fund targeting a total of $200 million.
