$2 billion startup GitHub just lost another key executive amid big changes at the company

GitHub VP of Engineering Susan Lally has parted ways with the company, she confirmed on Tuesday afternoon - just the latest in a string of executive departures at the immensely popular startup.

GitHub, often described as the "Facebook for programmers," is said to have been valued at $2 billion when it raised $250 million in funding last year.

The executive team has seen some shakeups under GitHub cofounder Chris Wanstrath, who took over as CEO in 2014 after accusations of harassment in the workplace led to the departure of cofounder Tom Preston-Werner.

Eight other executives have left over the past few months, as reported by TechCrunch and The Information, including: Strategy VP Brian Doll; head of product and partner marketing Marco Di Giacomo; Human resources VP Kelli Dragovich, and CFO Vlado Herman.

Now we can add Lally to that list. Lally, a 20-year tech industry veteran who spent a decade at Adobe, served as VP of Engineering for 18 months, remotely from the Boston area, per her LinkedIn.

"I also met with Susan and we agreed that now was the time for new leadership in engineering. We explored other opportunities within the company, but ultimately Susan has decided to part ways with GitHub," said Wanstrath in an e-mail to the company, as obtained by Business Insider.

All of this is amid the backdrop of apparently mounting customer frustration at GitHub: A bunch of the most active and influential GitHub users got together in January 2016 to co-sign a letter called "Dear GitHub," basically a list of feature requests that they felt have been ignored by the company. GitHub has since said that it plans on addressing those points specifically in the near future.

"Susan has helped us grow and develop immensely as an engineering organization during a period of unprecedented growth. We're grateful to her for her service, and her impact will be felt for years to come," said a GitHub spokesperson.
