Toyota Motor Corp. announced today it will invest $1 billion in Grab Holdings Inc., a Singapore-based human cloud, ride-sharing firm. A new report by Staffing Industry Analysts ranks Grab as the fourth-largest business-to-consumer human cloud platform after Uber, Didi Chuxing and Lyft.

Grab’s deal includes appointing a Toyota executive to Grab’s board. In addition, a Toyota executive will be seconded to Grab to serve as an executive officer at the company.

Grab operates in 217 cities in eight Southeast Asian countries. It acquired Uber’s Southeast Asian assets in March.

“We are thrilled to have Toyota on board as a long-term, strategic partner of Grab’s,” said Anthony Tan, co-founder and CEO of Grab. “This strong partnership will enable us to become the one-stop mobility platform in Southeast Asia.”

Toyota and Grab have also worked together since August 2017 with a data-transmission driving recorder developed by Toyota installed in 100 Grab cars.

“I am delighted that we are strengthening our collaboration, which utilizes Toyota's connected technologies, with Grab, Southeast Asia's leading ride-hailing company,” said Shigeki Tomoyama, Toyota executive VP and president of Toyota’s in-house Connected Company. “Going forward, together with Grab, we will develop services that are more attractive, safe and secure for our customers in Southeast Asia.”

Separately, The Detroit News reported this week that GM CEO Mary Barra said the automaker was distancing itself from Lyft and that it had no projects underway with the platform provider. GM President Dan Ammann also stepped down from Lyft’s board last week. GM had invested $500 million in Lyft in 2016.
