Facebook’s Josh Miller has announced that he’s leaving the social networking company today. Perhaps better known as the founder of Branch Media, Miller spent nearly the past 1.5 years as a product manager at Facebook. He did not provide any other statement about his future plans, saying: “More on what’s next very soon!”

Prior to joining Facebook via acquisition, Miller’s startup produced two services: the conversation service Branch and the link-sharing service Potluck. Both were shelved following Facebook’s purchase. While he’s been at the Menlo Park, Calif.-based company, Miller has worked on products like the collaborative video app Riff, anonymous app Rooms, and others.

In January 2014, Miller became a venture partner for investment firm Betaworks, which recently added former AOL executive Peter Rojas as its entrepreneur-in-residence (EIR).
