We’re hearing rumors that Twitter CTO Greg Pass has as of today left his post at Twitter, according to a source familiar with the company.
Prior to becoming CTO, Pass held the VP of Engineering position at Twitter, after being CTO and co-founder at Summize, which was acquired by Twitter in July 2008 and was eventually turned into Twitter Search. Prior to Summize, Pass was Systems Architect at AOL.
As VP of Engineering, Pass was responsible for taking the Twitter development team from a dozen engineers to around 10 times that number and played a seminal role in Twitter’s scaling success.
I’ve contacted Twitter PR for more information and have yet to hear back. I’ve also heard no word on who will be replacing Pass or what Pass’ future plans are.
Update: Twitter co-founder Biz Stone has confirmed that Pass will be leaving, with the below tweet. PR Representative Sean Garrett says that Twitter is not looking for a replacement and that Greg Pass currently has no future plans set in stone.
