After Earthlink, Sky Dayton is now focusing on two new ventures, Boingo Wireless and Helio, both of which have tight connections with the pioneering Internet service provider. Earthlink, which won contracts to build WiFi networks in cities such as New Orleans, San Francisco, and Anaheim, California, pays for its clients’ use of Boingo software. The company, where Dayton remains a major shareholder after Earthlink’s marriage with MindSpring Enterprises in 2000, is one of Helio’s co-owners (the other being South Korean communications giant SK Telecom). The telephone operation business is targeting the under-30 group owning Internet-capable phones. Earthlink believes Helio will gain 3 million users by 2009.
