Los Altos, Calif. -- Ness Computing, a Los Altos-base developer of search technology that provides personalized recommendations based on people's tastes and preferences, said on Tuesday it has raised $15 million in its second round of funding, led by SingTel Innov8. American Express Ventures also participated in the round, which the company will use to continue development of its core technology, which uses advanced machine learning techniques to recognize patterns in large sets of data. The company's first product, the Ness Dining Guide, is an iPhone app that uses "likeness scores" to predict how much someone will like a restaurant based on their unique preferences. The latest release adds restaurant reservations through OpenTable, as well as hundreds of thousands of menus, including prices. The year-old company now has plans to expand into new markets, such as nightlife, events, movies and shopping. "By enhancing our core technology, we can improve our understanding of what customers are expressing about themselves, and turn that information into something truly valuable for making decisions," said co-founder and CEO Corey Reese.
