Tara (Last name unknown) was a minor/ recurring character who appears in two episodes of HBO's Silicon Valley. She is an American women, portayed by Milana Vayntrub, who is introduced as Bertram Gilfoyle's girlfriend.
In "Third Party Insourcing" she comes to stay at the Hacker Hostel whilst visiting Gilfoyle and meets the Pied Piper gang for the first time. Like Gilfiyle, she is a LaVeyan Satanist and is seen attending meetings with him and his church. Her relationship with Gilfoyle is described as open and long-standing though she still lies to him about the people she sleeps with.
She reappears in the third season episode "To Build a Better Beta" where she is shown to be talking to Gilfoyle via the video chat on his computer. Unbeknown to the rest of the team, Gilfoyle had sent her the beta for the Pied Piper system and she thinks it great and seems to be working as a bug tester/ finder.
