Jelly continues building ex-Twitter talent with addition of #music’s Kevin Thau

It’s still unclear what former Twitter co-founder Biz Stone is up to with his startup Jelly, but he’s added yet another top Twitter executive to help him run the mobile-oriented stealth startup. Stone has nabbed former Twitter executive Kevin Thau, who was instrumental in launching the new Twitter #music app just weeks earlier, to join Jelly, Stone announced Monday.

Thau’s departure from Twitter for Jelly, which was first reported by AllThingsD a few weeks ago, was formally announced by Jelly in a blog post. Thau will serve as COO for the young company in charge of business operations, product management, and revenue. Stone noted that Thau had the idea for music discovery and put together the team to launch Twitter #music, which debuted just a few weeks ago.

Stone has already announced that Ben Finkel, formerly engineering manager at Twitter in charge of user growth, would be joining Jelly to serve as co-founder and CTO. That’s a lot of talent leaving Twitter for Jelly, as Stone noted in his blog post highlighting all of Thau’s achievements at the emerging media company:

“Kevin gave Twitter a lot—he built and managed the mobile engineering and design team responsible for launching SMS, Blackberry, iPhone, iPad, and Android applications. Later, as Vice President of Business & Corporate Development, Kevin created strategic partnerships with RIM and Apple to get Twitter deeply integrated in to every Blackberry, iPhone, iPad, and Mac. Kevin’s approach to partnerships is essentially, “How can we help?” and I’ve always loved that. At the beginning of 2012, Kevin took an idea he had for a fresh approach to music discovery, built a team, and led the development of Twitter #music.”

Jelly is one of several startups under the Obvious Corp. umbrella that’s run by former Twitter founders and early employees, including Jason Goldman‘s Branch and Evan Williams’ more independent company Medium.
