TAG is an acronym of Techniques d'Avant Garde. The parent company, TAG Group (Holdings) S.A., is a private holding company, with subsidiaries primarily involved in motorsports, aviation and other industries. They are currently based in Luxembourg.

The company was formed in 1977 by Akram Ojjeh, a Syrian-born Saudi businessman. It was intended to focus on advanced technologies. Their initial dealings were facilitating the purchase of French armaments and military vehicles by the Saudi government. The company is now run by Akram's son, Mansour Ojjeh.

Through their colleagues at Saudia Airlines, TAG became involved in the world of Formula One, and sponsored Williams for several years in the 1980s. They later designed and funded a turbocharged V6 engine, built by Porsche and used by McLaren.
