Mountain View, Calif. -- Google Ventures, the investment arm of Mountain View-based Google, has co-led a $1.2 million seed round for Michigan-based Roqbot, developer of a mobile jukebox app. Detroit Venture Partners also co-led the round, which included participation from Accelerator Ventures, T5 Capital and Penny Black. Patrons at Roqbot locations use an iPhone or Android music app to check in, discover what's playing, request songs, vote on the queue and see the venue's specials. Ultimately, customers crowd-source the music experience at that location. "With just a few clicks, a bar can have a playlist that dynamically adjusts to customer feedback while still letting the business owner maintain control," said co-founder and CEO Garrett Dodge.
