Tech’s “sharing economy” movement has spawned companies like Airbnb and Relay Rides, which let people save and make money via exchanges for things like spare bedrooms and car trips.

Now a new slew of startups is using the model to match consumers with professional services for less.

YourMechanic, for instance, has a mobile network of certified auto mechanics who will come to your home or office; Pathjoy promises “maid service for the masses,” booked online. Similar exchanges are popping up for chefs (Kitchit) and barbers (GoHaircut).
