Takeout Tycoons GrubHub and Seamless Merge

Yahoo and Tumblr weren't the only online properties getting into bed together today: GrubHub and Seamless, two of the largest food-delivery websites in the US, have announced a merger, combining forces to fend off an increasing number of startup rivals, Bloomberg reports. "This has nothing to do with cost savings; it has everything to do with increasing growth," says GrubHub's co-founder. "We’re totally focused on the top line and how we continue to drive more orders for our restaurants."

The two companies had a combined revenue of $100 million last year, processing $875 million in food sales. The merged company will offer ordering from 20,000 restaurants across 500 cities, adds CNNMoney. The deal still has to be approved by regulators. (More grubhub stories.)
