Filings with the SEC have revealed that Harmonix has recently received a $15 million investment. Those responsible for the influx of equity funding have chosen not to disclose their identities, though.

The filing lists that a group of 14 investors has made possible the funding, which comes just a month before the release of Rock Band 4. Harmonix is headed into a battle of the bands, as Activision is also bringing back its console music series with Guitar Hero Live.

Harmonix is also in the process of completing Amplitude, its first foray into crowdfunding. The title was recently delayed, with wide release planned for early 2016.

The company also recently announced it will be returning to crowdfunding later this year, this time via the new Fig platform. Harmonix chief creative officer Alex Rigopulos has also joined that group’s advisory board.

We've reached out to Harmonix for comment. We'll update should we receive a response.

Update: Harmonix says it will be talking more about this investment in the comings weeks, but has no comment on the matter for now.

Our Take

Harmonix and its hardware partner, Mad Catz, both have a lot riding on Rock Band 4. This latest investment comes at an important moment, but it also means there is added pressure to deliver. Provided the new game has a solid launch, Harmonix has a history of delivering strong DLC over extended periods of time. That kind of bridge to the next major product will help immensely.
