After Launching #Music, Kevin Thau Becomes Latest Employee To Leave Twitter For Biz Stone’s Jelly

Less than one week after Twitter Music’s launch, Kevin Thau, the man responsible for the standalone app, is leaving the company to become COO of Jelly, Twitter co-founder Biz Stone’s mysterious, mobile-focused startup, according to AllThingsD.

Thau will be the second high profile Twitter employee to join Jelly: a couple days ago, Stone introduced former Twitter engineering manager Ben Finkel as his co-founder. In addition, Twitter’s first designer Vítor Lourenço, who left the company in November, is also serving as a consultant for Jelly.

Thau joined Twitter in 2009 as its “first official business development guru,” after a stint as vice president of sales and business development at Buzzwire. Before leading Twitter Music, Thau managed the mobile engineering and design teams responsible for launching the first versions of Twitter’s mobile apps before moving on to become VP of business and corporate development.

Jelly is still very much under wraps, but the startup released a few hints earlier this month. In a blog post titled “What Is Jelly?,” Stone said the startup will be for “everybody” and “developed first and foremost for mobile devices,” which means the addition of Thau to its roster is a logical move. TechCrunch’s Drew Olanoff and Josh Constine speculated that the Jelly team might be developing something that will help connect people to connect to social causes and show off their contributions.
