Travis Kalanick’s robotics startup Atoms is pushing aggressively into autonomous vehicle tech, planning a major hiring spree and potential acquisitions to accelerate development, according to a Financial Times report.

Uber has previously invested about $100 million in Atoms and maintains a broad network of autonomous-vehicle partnerships that could facilitate collaboration.

Discussions have taken place about Uber using Atoms’ robotaxi technology, signaling potential collaboration or licensing arrangements between the two companies.

Atoms previously acquired Pronto, an autonomous mining startup led by Anthony Levandowski, linking Atoms’ leadership to prominent figures in the U.S. autonomous-vehicle scene.

The robotaxi focus is central to Atoms’ strategy and aligns with Kalanick’s view of the recent funding round as unfinished business, even as the company’s portfolio likely extends beyond robotaxis.
