"This is isn't any negative on Silicon Valley. We think Silicon Valley is awesome," Case said. "But there are also a lot of great entrepreneurs in other parts of the country and there is not as much capital focused on them."
About 40 per cent of the venture capital invested in US startups is concentrated in Silicon Valley, based on statistics compiled by PwC and the National Venture Capital Association.
The newly minted Revolution Ventures fund has already invested undisclosed amounts in four startups scattered around the country. They are: Chicago's BenchPrep, an online service that helps students prepare for academic tests; New York's Booker Software, an online business management service; Washington DC's Homesnap, the maker of a mobile residential real estate application for mobile devices; and Boston's RunKeeper, the maker of a free health and fitness app for mobile devices.
The Revolution Ventures fund is based in Washington, DC, not far from the Virginia offices where Case turned America Online into one of the internet's first success stories.
Case stepped down as AOL's chairman a decade ago, a few years after the company bought Time Warner and eventually moved its headquarters to New York.
The union between AOL and Time Warner turned into a monumental flop that saw the combined company absorb about US$100 billion in charges to account for its diminished value.
AOL was spun off from Time Warner in 2009 and now has a market value of about US$2.7 billion.
Case is running the Revolution Ventures fund with two of his partners, Tige Savage and David Golden.
