Einride is adding 75 of its electric heavy duty trucks to Amazon’s Relay freight network as part of a deal that gives the Swedish startup a toehold in the e-commerce giant’s operations. Einride will also provide charging infrastructure across five locations in the United States, under the agreement announced Tuesday.

Amazon isn’t buying or operating the electric trucks. Instead, Einride will own and manage (using its own Saga AI software) the trucks, which can be used by drivers in Amazon’s Relay freight network. Relay, launched in 2017, is an app that truck drivers can use to book hauling gigs with Amazon.

Einride CEO Roozbeh Charli, who took over as chief nearly a year ago, said working with Amazon is a powerful validation of the startup’s technology and strategic vision.

“By deploying our intelligent platform within one of the world’s most sophisticated logistics networks, we are accelerating growth, while continuing to build industry-leading operational expertise,” he said in a statement.

Einride has gained attention and investment for its two-pronged approach to freight. The company has developed and now operates a fleet of about 200 heavy-duty, electric trucks for companies like Heineken, PepsiCo, and Carlsberg Sweden in Europe, North America and the UAE. It has also developed autonomous pod-like trucks, which stand out for their cab-less design.

The agreement with Amazon doesn’t include the autonomous pods.

Einride has landed this agreement at a critical time: The startup is finalizing a merger with blank-check company Legato Merger Corp. and is expected to go public soon.

While the agreement might not carry the same weight for Amazon, which has a market cap of $2.7 trillion, it does contribute to its low-carbon goals. Amazon has said it wants to reach net-zero carbon emissions across its operations by 2040.

“This rollout is an important step forward in addressing one of the toughest challenges we face in decarbonizing our transportation network — electrifying heavy-duty trucking,” an Amazon spokesperson said in an emailed statement. “We’re excited to continue to collaborate with Einride and learn from these operations as the trucks hit the road.”
