The alliance said in January it was setting up the fund with plans to invest as much as $1 billion over five years, the latest move by major carmakers as they seek to adapt to rapid industry change by investing in startups.

"The idea is we will do one new investment a month," Francois Dossa, the head of Alliance Ventures, told Reuters by phone ahead of this week's Ecomotion conference in Tel Aviv.

It invested in Ionic Materials, a U.S.-based firm developing solid-state cobalt-free battery materials; French-based Kalray that has developed a microprocessor that can be used in autonomous driving; and Shift, a Silicon Valley platform to buy and sell used cars.

It also invested in Sinovation Ventures, itself a Chinese fund focused on artificial intelligence, and has made a decision to invest in Israel's Maniv Mobility, another car technology fund also backed by Jaguar Land Rover and Valeo.

"We think this is a good way for us to better understand the Israeli ecosystem ... where we see big potential," Dossa, a former banker, said, adding it was "a question of probably days," until the deal with Maniv is signed.

He declined to provide details of the sixth investment that has not yet been approved.

Alliance Ventures is seeking investments in new mobility, vehicle connectivity, autonomous driving, enterprise technology and energy, including electric vehicles and batteries.

It works closely with the alliance's innovation labs, including one it has at Tel Aviv University for co-development and testing of Israeli technologies.

Alliance Ventures is 40 percent held by Renault, 40 percent by Nissan Motor Co and 20 percent by Mitsubishi Motors Corp.

The fund's goal is strategic - to find technologies that will be part of new mobility services in the future, Dossa said.

"We expect to make a profit but the idea is the profit will be reinvested in the fund," he said.
