AdExtent

AdExtent (formally Semantinet) is an Israeli startup company dedicated to developing RTB Display technologies for various ad platforms.
History.
The brainchild of Tal Muskal, who initially intended to create a development platform for the seamless integration of data, Semantinet was incorporated as a company in December 2006, after receiving a preseed investment from Yossi Vardi.
The company completed hiring its development team in January 2008, and by April the same year the team completed development of the company's initial semantic web engine. Three months later, in July 2008, Semantinet released its first product, the Headup client, as a private Alpha. In October the client was deemed ready for Beta and in February 2009 it was approved for distribution via Mozilla's Firefox Addon directory.
In March 2009 Semantinet began the transition from client to server based solutions and in July it started a pilot of a semantic web WordPress plugin for bloggers. The product was made publicly available via the WordPress plugin directory in October 2009. In January 2010 the server based Headup solution was made available as a Joomla extension and in March it became available as a Drupal module.
Products and services.
Semantinet has released to date two applications to Beta. The company's first application, the Headup Semantic Web Firefox extension enables users to highlight terms appearing in web content in order to discover related content provided in the extension's overlay window user interface.
The company's second application is the Headup website and blog extension, which automatically identifies and highlights topics appearing in a publisher's web content. Users interacting with the plugin's highlights are provided related articles, images, videos, Tweets, etcetera, via one of three configurable interfaces.
Management.
Semantinet was founded and is currently managed by Tal Keinan and Tal Muskal, who, like many of Israel's startup community members, served in the IDF in information technology related roles. Keinan, who's assumed the role of CEO and serves on the company's board, worked at Morgan Stanley's Risk Management Department prior to founding Semantinet, while Muskal, who invented Semantinet's core technology and now serves as its CTO, worked as an R&D engineer at Go Networks, where he made his first pitch about the technology to Oz Leave, Go Networks' CEO, who now serves as the Chairman of Semantinet's Board of Directors.
