Correction: The story has been corrected to reflect that was launched in 2011, not 2009.

The Washington Post Co. this week announced that it has agreed to invest an undisclosed amount of money in, a two-year-old online service that helps people find churches and religious communities.

The Post Co. will share content from its flagship newspaper’s Web site with, and OnFaith’s editor, Sally Quinn, will work with FaithStreet’s executives. The two sites hope to drive additional traffic to each other.

FaithStreet’s Web site says its three founders started the business in New York City in 2011 because “there was no high-quality, online service that provided information to help a newcomer to a city (or to the faith) discover and explore churches and Christian communities near them.”

The site is now a collection of thousands of Web pages about Christian congregations and their pastors. It plans to make money through premium services and advertising.

The chief executive, Sean Coughlin, served as president of Harvard’s Reformed University Fellowship and did mission work in Asia with Campus Crusade, according to the FaithStreet site.

Coughlin, a graduate of Harvard College and the University of Virginia law school, is a member of Dwell Church in the Bowery area of Manhattan. The church combines rock-and-roll and bluegrass music with traditional hymns, the Web site says.
