Factual – Open Data Platform and Community
http://www.factual.com/

Factual was founded in 2007 by Gil Elbaz, co-founder of Applied Semantics (which launched ASI’s AdSense product). Applied Semantics was acquired by Google in 2003. Gil has had a lifelong passion for organizing and structuring information, and building smart tools which can make better sense of data. To that end, he set out to develop an open data platform and community in an effort to maximize data accuracy, transparency, and availability. Fellow data lovers — Tim Chklovski, chief scientist & founding engineer, Eva Ho, an ex-Googler, along with Bill Michels, former GM of Yahoo BOSS, have joined him in this ambitious project.
