  • Team: Brian Shortsleeve; Gabriel Ling (ex-General Catalyst) and Michael Anello (ex-VP of Valor Equity's operations group).
  • Per Shortsleeve: "One of the areas I really focused on at the [MBTA] was leveraging technology and industry. For example, we launched a big partnership with Uber and Lyft...
