AsianFin -- Coco Robotics, a Los Angeles-based startup focused on last-mile delivery robots, has secured $80 million in fresh funding, the company announced Wednesday.

The round saw participation from prominent angel investors Sam Altman and Max Altman—both existing backers—as well as venture firms including Pelion Venture Partners and Offline Ventures. With this latest raise, Coco’s total funding now tops $120 million. The company last raised $36 million in a Series A round in 2021.

Coco’s compact, zero-emissions delivery robots can carry up to 90 liters of goods and have completed over 500,000 deliveries since debuting on public roads in 2020. Its client roster includes national chains like Subway, Wingstop, and Jack in the Box.

Sam Altman’s connection to Coco extends beyond investment. In March, Coco partnered with OpenAI—where Altman serves as CEO—to integrate OpenAI technology into its robots. The collaboration allows Coco to leverage advanced AI while providing OpenAI with real-world data to help train its models.
