An Instagram for Music? Yep–And It’s Hot. VERY Hot.

How many social networks does the world really need? The market is apparently still wide open. Witness the crazy success of Acapella.  From Forbes:

Six weeks ago Ihung Tu and his cofounders in Mixcordlaunched their latest app, Acapella, which lets users record, synchronize and share a cappella versions of songs. Performers record themselves singing different parts of a song and the app stacks those videos one over the other, creating both an a cappella song and a window-pane like video showing how it comes together.  The app has blown up, in large part, because of a strategy that came about after Tu, CEO, and his cofounders Daniel Vinh, vice president of marketing and business development, Joey Pascual, vice president of product and Andrew deSilva, vice president of operations, joined the L.A.-based startup accelerator Muckerlab last July.

Mixcord had another app—PicPlayPost– which sold for $1.99 and has been very successful. But Tu and his cofounders decided to take the advice of Will Hsu, Muckerlab’s cofounder and managing partner, and made PicPlayPost–which was pulling in seven figures annually—free. “Will felt that we could build something much larger. Did we want to keep this as a small company doing good revenue for a team of six, or did we want to scale up and build up like a Google. The opportunity was there,” says Tu. “It wasn’t an easy decision.” But it seems to have been the right one. Making PicPlayPost free allowed Mixcord to grow its network of just under 600,000 users to more than three million in 12 months. With Acapella, the platform went from three million users to 10 million in 30 days.

Holy shit! Keep reading.
