Progressive Corp/oh/
One of the largest U.S. auto and home insurers, Progressive sells policies like car, motorcycle, and renters insurance both through tens of thousands of independent agents and directly online or by phone. Founded in 1937 by two Cleveland lawyers who spotted an opening while investigating door-to-door insurance salesmen, the company pioneered usage-based coverage with its Snapshot device that tracks driving habits to set rates.
