Amazon just bought a startup making kid-size humanoid robots
Amazon has been quietly amassing a robotics portfolio. Its latest acquisition makes that strategy unmistakable.
Amazon confirmed Tuesday it has acquired Fauna Robotics, a two-year-old New York startup building kid-size humanoid robots — the company's second robotics acquisition in the same month it also bought Rivr, a Zurich-based startup with a stair-climbing delivery robot. Terms of both deals were not disclosed.
Fauna launched its first product, Sprout, earlier this year — a 50-pound bipedal robot that ships to select research and development partners at $50,000. The company was founded by former Meta and Google engineers and employed roughly 50 people before the acquisition, all of whom — including the two founders — are joining Amazon in New York City.
"We are excited about Fauna's vision to build capable, safe, and fun robots for everyone," an Amazon spokesperson said in a statement. "Together with Amazon's robotics expertise and decades of experience earning customer trust in the home through our retail and devices businesses, we're looking forward to inventing new ways to make our customers' lives better and easier."
The deal gives Amazon something it has struggled to build on its own: a consumer humanoid with real-world traction. Fauna signed Disney and Hyundai's Boston Dynamics as early customers before the acquisition closed — a meaningful signal that the platform had appeal beyond a science project.
Amazon's robotics history is a study in mixed results. It bought Kiva Systems for $775 million in 2012, building the foundation for the million-plus warehouse robots now deployed across its fulfillment network. But its consumer robotics efforts have been harder. Astro, a squat home robot priced at $1,600, never achieved meaningful scale and is now largely forgotten. A planned acquisition of robot vacuum maker iRobot was abandoned in 2024 after regulators blocked it in both the U.S. and Europe.
The Fauna acquisition suggests Amazon has shifted strategy: instead of building consumer humanoids from scratch, it is acquiring proven platforms and the talent that built them. Sprout's developer-focused positioning — it is pitched as a platform for academic and corporate robotics research, not a household appliance — means Amazon is inheriting a research community along with the hardware. That is a different kind of acquisition than iRobot's roomba-and-data play.
The Rivr deal, confirmed by Amazon earlier this month, adds a complementary piece. Rivr's stair-climbing delivery robot targets last-mile logistics, which fits Amazon's core retail business in a way that Sprout — for now — does not. The pairing signals that Amazon is interested in both the home and the doorstep, even if it is keeping quiet about specific product timelines.
For the robotics industry, the acquisition adds another major tech company to the consumer humanoid race. Tesla's Optimus, Figure AI, 1X, Apptronik, and China's Unitree are all competing for position. Amazon's advantage is not the robot — it is the distribution: 300 million active customer accounts, an existing smart-home ecosystem via Alexa, and the supply chain relationships to actually manufacture at scale if the market materializes.
The question is whether Sprout's research platform positioning translates into a consumer product. Right now Amazon has two robotics acquisitions in one month and a humanoid robot it is calling a developer tool. That is a portfolio, not a product line. The next chapter — what Amazon actually does with Fauna's platform — has not been written yet.
