Yelp is acquiring Eat24, the online delivery and pickup service that competes with GrubHub, Delivery.com and other national and regional players for order-taking, food search and discovery. The service is being acquired for the equivalent of $134 million ($75 million in cash and 1.4 million Class A shares).

Eat24 currently provides menus, order-taking and tracking services for more than 20,000 restaurants in 1,500 cities — 10,000 fewer than GrubHub. Like GrubHub, its revenue model is based on commissions (industry standards are typically 10-12 percent per order.) The service is free to the consumer, although restaurants can charge their own delivery fees.

The service is largely dependent on customer pick up at restaurant locations, but delivery is becoming a larger factor. In several California cities, for instance, Eat24 will soon be providing delivery via SideCar, the shared-car service.

Founded in 2008, Eat24 has been integrated with Yelp’s mobile app since 2013. By bringing Eat24 in-house, Yelp can strengthen its platform of services, which have grown beyond advertising and now includes scheduling, reservations/booking and offers. Yelp reports that it has over 93,000 active local accounts.

While Eat24 currently lags behind GrubHub, online delivery is still a nascent category. Moreover, it is ripe for cross-over activity with other food-related segments, including rating/reviews (i.e Yelp and Zomato, which just acquired IAC’s UrbanSpoon); online reservations (i.e. Priceline’s OpenTable); and eventually even grocery delivery (i.e. Amazon, WalMart and Google.)
