OLO celebrated its eighth birthday on June 2. The online ordering and mobile application allows for digital payments and ordering from multiple chain restaurants.

The nation's leading restaurant chains have come to understand that mobile apps are the perfect platform for customer engagement. OLO's digital ordering engine is empowering these restaurant chains to better serve their loyal customers and attract new ones with award-winning native mobile apps for iPhone and Android (and desktop and mobile web ordering sites) that allow customers to order and pay from everywhere. A faster, personalized, elegant customer experience is what foodservice is all about.

It's been an incredible journey so far and the company is only just getting started, with 58 percent of mobile phone users now using smartphones and smartphone users now reaching for their phones around 150 times per day.

OLO has almost 3 million users, which is a milestone that founder and CEO Noah Glass said is just the beginning. OLO recently announced a partnership with mobile tech provider CorFire to add more functionality to restaurants’ mobile apps, including the option of using mobile phones to pay with stored gift cards. That came on the heels of a $5 million investment from PayPal, which is working to expand its payment services to brick-and-mortar establishments.

And this week brought more good news. For restaurant chains with 30 or more units, OLO is the only way they can get their menus listed on GrubHub, a deal made all that much sweeter by the news that GrubHub will merge with New York City-based online ordering service Seamless.
