According to TC, Wag has quietly raised Series A and B funding from General Catalyst and Sherpa Ventures.

Founded in January 2015, Wag! is an on-demand app-based mobile service that allows dog owners to hire fully trained, background checked, insured and bonded dog walkers for 30 to 60 minute walks. The app notifies owners when their dog is picked up and allows them to follow the walk through Wag!'s GPS 'Puppy Tracker'. When the walk is finished the owner receives a report card indicating distance travelled and time, along with a 'pee & poo' record, a photo/video and any notes the walker may need to communicate. For every mile a dog walks with Wag!, 10 cents is donated to the Best Friends Foundation.
