João Barros, the former national director of the Carnegie Mellon Portugal program, and Susana Sargento, a professor at Portugal’s University of Aveiro, have launched Veniam, a startup that harnesses public transportation fleets to deliver Wi-Fi access to citizens. The service, also co-founded by Zipcar’s Robin Chase and Roy Russell, hopes to be an enabler for the Internet of Things — a movement to connect a variety of products online — and a solution for affordable Internet access.
