CHICAGO – Grubhub has entered an agreement to acquire online food-ordering service Foodler for an all-cash transaction. Additional details of the deal, which is subject to certain closing conditions, were not disclosed.

Boston-based Foodler, one of the largest independent food-ordering providers in North America, will add more than $80 million of annualized gross food sales in 2017, according to Grubhub. The buyout also expands Grubhub’s presence in New England and the company’s national footprint of more than 55,000 existing restaurant partners and 8.8 million active diners.

“We’re thrilled to bring Foodler’s scale and its established diner base in the Northeast to Grubhub,” Matt Maloney, Grubhub CEO, said in a statement. “Its addition will enhance the Grubhub marketplace — particularly in Foodler’s hometown market of Boston — allowing us to connect our diners with an even broader range of top-rated, popular local restaurants.”

The Grubhub portfolio of brands also includes Grubhub, Seamless, AllMenus and MenuPages.
