Twitter's consumer product boss Jeff Seibert, who just took over Twitter's core product team back in September, is no longer running Twitter product, according to multiple sources. Seibert, who co-founded Crashlytics, will go back to running Twitter's developer product suite Fabric, which he was doing before the promotion in the fall.
Twitter does not have a permanent replacement for Seibert, and is opening up a search to fill the role, according to sources. Ed Ho, a senior engineering director who has been at Twitter for two years, will take over Twitter's product on an interim basis.
A spokesperson confirmed the moves, and offered this statement:
"This year we're focused on delivering on five product priorities — refining our core service, live-streaming video, creators, safety, and developers — as well as recruiting great talent. We've successfully increased our shipping cadence on our core service and have asked some of our top leaders to take on key roles in the other priority areas."
Seibert was the fourth person to run Twitter's core product since early 2014. He took over the day-to-day consumer product responsibilities from then-VP of Product Kevin Weil, who would later move on to take the same role at Instagram as part of a massive executive exodus from Twitter in January. Seibert's appointment was the first major restructuring move by CEO Jack Dorsey, who was still technically "interim" CEO at the time.
