BiteHunter logoDining deals search service BiteHunter has closed a new $800,000 round of funding, the company announced today.

BiteHunter is a real-time search engine that lets you seek out dining deals from over 400 different sources, including Facebook, Twitter, Groupon and LivingSocial. It also gives you info about restaurants and reviews from others — sort of like a Kayak for eating out.

The company plans to use the new funding to grow its presence on mobile platforms. BiteHunter is already available on the iPhone, but it will soon be available on the iPad and Android, co-founder Gil Harel told VentureBeat.

The company is working on two big additions to its mobile app experience. The first is a new notifications system that will send out customized dining alerts based on a user’s social activity on Facebook, Foursquare and other social networks. The second addition will allow BiteHunter users to purchase deals within the app.

“One of the problems many deal aggregators have is that when you send someone outside of the app to make the purchase for the deal, those third parties don’t always support mobile. The users have to sign in again, re-enter credit card information … the user experience is not great,” said Harel.

Both the new notification system and the in-purchase functionality is scheduled to roll out in early 2012, Harel said.

Founded in 2010, the New York-based company previously raised $250,000 in angel funding. The new round is led by angel investors Avraham Kadar and Eyal Chomsky and brings the startup’s total funding to $1.05 million to date. The startup faces indirect competition from Yelp, CitySearch and UrbanSpoon.
