Health search engine Healthline raises $14M

Healthline Networks, a company that offers health search technology on its own website and on partner sites like Yahoo Health, has raised $14 million in a third round of funding.

The San Francisco company brings a semantic approach to health search, meaning that it has a deeper understanding of a user’s search than a normal engine. It says it has created a “taxonomy” of different medical terms, so it can deliver uniquely useful search results for people researching their own health and sickness. Healthline was founded in 1999 and launched in 2005. It says that it now reaches more than 100 million users every month through its site and its more than 40 publishing partners, including, Aetna, AOL, Elsevier, GE,, Ingenix, iVillage, Medhelp, United Health Group, U.S. News and World Report, and Yahoo.

The company also says that it reached profitability last year. It is raising the new funding to expand research and development, engineering, and advertising, it said. The round was led by Investor Growth Capital, the venture arm of Investor AB, with participation from GE/NBC Universal’s Peacock Equity Fund.

Healthline has now raised $72 million in funding.
