India, Jan. 22 -- Startup Vapor IO scored $90 million in a Series C venture capital funding round from private equity firm Berkshire Partners and cell tower giant Crown Castle. The company said it would use the cash to finance its ongoing construction of mini data centers for edge computing around the US.

"It takes a lot of capital" to build this kind of thing, noted Cole Crawford, founder and CEO of Vapor IO. Cole said the company has so far raised "well north" of $100 million in total VC financing, but he declined to provide specifics.
