— Xbox Chief Operating Officer Helen Chiang has suddenly left Microsoft after 21 years with the company, just months after landing the role in July. Her past roles include leading Mojang and the Minecraft franchise.

Verge first reported the news on Friday, citing a memo from Xbox CEO Asha Sharma that did not disclose the reason for her departure.

An Xbox spokesperson was likewise mum on details. “We don’t discuss individual personnel matters. We’re grateful for Helen’s years of service and wish her well,” the company said in an email to GeekWire.

Xbox has undergone a massive reorganization that included Chiang’s appointment, roughly 3,200 job cuts through the fiscal year — about 20% of the Xbox workforce — the spinoff of four game studios and a plan to dramatically flatten management.

— More leadership changes are underway at SeekOut, a Bellevue-based recruiting startup launched in 2017. The company announced Monday that co-founder John Tippett is now president, moving from his role as chief client officer.

In April, SeekOut CEO and co-founder Anoop Gupta retired and passed the reins to enterprise software veteran Sean Thompson. In August, co-founder and chief technology officer Aravind Bala took over as CEO. Thompson is now listed as an adviser to the board.

Tippett will lead day-to-day operations and work with Bala “on the company’s direction,” according to a press release. SeekOut said it wants to integrate AI tools into customers’ operations to reduce recruiters’ workload.

SeekOut is No. 68 on the GeekWire 200, a ranked index of the Pacific Northwest’s top startups.
