Exelate, a startup that focuses on targeted audience data and data management tools for publishers, announced today that it has closed $15 million in second-round funding.

The company touts that its data exchange is “the first and largest open marketplace for audience targeting data” — making it a go-to choice for publishers that want to better target their ads to visitors. Last year, it launched the teXi:DM Data Management suite to better help publishers manage their targeted data, and last month it unveiled its teXI:PM Private Marketplace offering, which allows publishers “to create their own one-to-one transparent relationships with data buyers in a closed, privacy-friendly, highly functional data marketplace.”

Exelate says that proceeds from its latest investment round will go towards cementing the standing of its data marketplace, and to increase the functionality of its data management tools.

Based in New York, NY, Exelate’s latest funding round was led by Menlo Ventures and Carmel Ventures. The latter previously invested $4 million in the company’s first round — bringing its total funding thus far to $19 million.
