Rover is one of the two big money pet service startups in the US (the other being competitor Wag.)
Rover is a digital marketplace where pet owners can find dog walkers, pet sitters and boarders, and, recently, pet groomers. Service providers pay Rover a 20% commission for work done through the network.
The company claims that it has more than 200,000 workers in 14,000 cities.
Rover came out of a Startup Weekend contest in Seattle in 2011.
