Rock Band developer Harmonix has raised $15m in equity funding.
The funding was provided by 14 undisclosed investors. There were however some new directors listed on the filing, which includes Foundry Group MD and Techstars founder Brad Feld.
Harmonix has experienced a turnaround in fortunes during the last year. The studio had been struggling and in May 2014 laid off 37 staff, which followed a small number of redundancies in the previous year. Studio founder and CEO Alex Rigopulos also stepped down from his role to become chief creative officer. VP of operations and publishing Steve Janiak replaced him as CEO.
