This Silicon Valley start-up — whose founders include two of the people that helped to start Zipcar — aims to build city-scale networks of connected vehicles that can expand wireless coverage. That means cars and buses, for instance, can become live networks that allow people to be online without being dependent on a cellular network. Veniam co-founder and CEO João Barros says the company can also take the data it collects to keep track of buses and other municipal vehicles and better manage traffic flows and alternate routes.

The company's technology can best be seen in Porto, Portugal, right now, where its hardware has been installed onto the public bus system. The company claims that 200,000 bus riders have access to Veniam's free mobile Wi-Fi there every day. In November it signed an agreement with StarHub, a communications provider in Singapore, to turn thousands of vehicles into mobile Wi-Fi hot spots, and in January it signed a similar agreement with a company in Mexico.

So far, the company, which recently opened offices in New York City as well, has raised close to $30 million from True Ventures, Cisco Investments, Union Square Ventures and Cane Investments, and from the investment arms of Verizon, Cisco, Orange, Yamaha Motors and Liberty Global.
