Inflection, an under-the-radar startup which owns genealogy website Archives.com, has raised $30 million in a first round of funding. The company charges users $39.95 a year to access historical records and build their own family trees on the site and it is apparently doing very well, despite competition from sites like Ancestry.com.

Inflection says it is profitable and traffic is up nearly 50 percent year-over-year. The company also launched a second site this week, a people search engine called PeopleSmart.

The cash comes from Matrix Partners and Sutter Hill Ventures. Some more details in Inflection’s announcement, as well as this write-up in the New York Times.
