Sonopia
Branded mobile phone services for brands, charities, environmental organizations and entertainment groups
About Sonopia
Sonopia was a mobile virtual network operator (MVNO) enabler founded in 2005 by Juha Christensen, a co-founder of Symbian. The company, based in Menlo Park, California, secured $21.5 million in total funding over two rounds, including a $12.7 million Series B in May 2007 led by Cardinal Venture Capital, with other investors like Sevin Rosen and Fuse Capital participating.
The firm's business model centered on providing a platform that allowed various organizations, groups, and even individuals to create their own branded mobile phone services. This was offered free of charge, with Sonopia managing the service, which ran on the Verizon Wireless network. The platform was designed to be user-friendly, enabling a new mobile service, complete with custom calling plans, phones, and exclusive content, to be set up online in approximately 15 minutes. Clients could essentially become their own virtual wireless carriers, marketing the services to their members or supporters.
Sonopia's target market included a wide range of entities, from local sports teams and charities to larger organizations. Early adopters of the platform included the National Wildlife Federation, the International Animated Film Society, and the Long Island Ducks minor-league baseball team. The revenue model involved Sonopia handling the back-end operations and service management while the partner organization focused on marketing to its community. Despite its novel approach to the mobile market, the company is now listed as deadpooled.
