Jun 2026Undisclosed stageToyota Invention Partners (lead)$6M$626MToyota invested JPY 1,000 million in Tier IV on June 9, 2026 through Toyota Invention Partners, taking a 1% stake in the autonomous-driving company. The stake was described as part of Toyota’s broader push to advance autonomous driving development and regional deployment, and the transaction was framed as a strategic partnership rather than a full acquisition. The investment aligns with Toyota’s effort to accelerate level 4 autonomous driving and build alliances with technology firms in key markets. Tier IV is positioned as a strategic fit because it develops autonomous driving systems and related services, including open-source software for self-driving vehicles. The transaction was also tied to Toyota’s broader initiative to support collaboration between development speed and safety in autonomous driving. Tier IV was founded in 2015 and is known for Autoware, an open-source autonomous driving software platform. In March 2026, it released a hardware-agnostic level 4 software stack compatible with multiple automotive-grade SoCs and sensors, and made it available globally through the Autoware platform at no cost. The company operates in autonomous-driving software and services, with the deal signaling continued expansion of its ecosystem and industrial partnerships.
