Twitter Opens Detroit Office In Rock Ventures' Madison Building

DETROIT (WWJ) - The microblogging site Twitter is opening an advertising office in downtown Detroit's M@dison Building, a tech company incubator owned by Rock Ventures LLC, entrepreneur Dan Gilbert's holding company.

The company wouldn't give a specific number of staff to be hired. Twitter spokesman Robert Weeks said that "a handful of Twitter employees at the Detroit office will work closely with automotive brands and advertising agencies."

"Over the past year, several marketers from the Detroit area -- including GM -- have worked with Twitter on Promoted Products campaigns," Weeks said. "Having a presence in downtown Detroit will make it even easier for us to work with these marketers face-to-face."

Based in San Francisco, Twitter is a communication Web site that connects users and allows them to share ideas, opinions and news. Posts on Twitter, called tweets, are limited to 140 characters. There are no ads on the Twitter site, but commerical users can mount campaigns of sponsored tweets.

Twitter joins a host of other tech companies in the five-story Madison Building. A complete listing of tech companies recruited by Rock Ventures to the Madison and its other downtown Detroit properties is below.

Rock Ventures said its property management firm, Bedrock Real Estate Services LLC, helped recruit Twitter and brokered the company's lease.

"Twitter coming downtown is exactly the kind of innovative company Detroit needs to advance our vision of becoming one of the most exciting high-tech and web-centered corridors of growth and activity found anywhere," said Gilbert, Chairman of Rock Ventures and Quicken Loans, and Majority Owner of the NBA's Cleveland Cavaliers. "Twitter chose Detroit because of the city's growing, young and energetic environment.  This is further proof that the country is starting to wake up and take notice -- if you want to create a thriving, growing tech business, downtown Detroit is one of the best places to be.
