Serve Robotics plans $29 million acquisition of Austin’s Diligent Robotics, bringing Moxi hospital robots onboard

Deal expands an outdoor delivery-robot platform into hospitals

An Austin-based healthcare robotics company, Diligent Robotics, is set to be acquired in a transaction valued at $29 million, as delivery-robot operator Serve Robotics moves beyond sidewalk autonomy and into indoor clinical settings. The agreement, announced January 20, 2026, calls for Serve to pay Diligent shareholders in Serve common stock, with the final value subject to customary adjustments tied to net debt and related items.

The merger agreement also includes a performance-based earn-out of up to $5.3 million if specified milestones are met. The companies expect the deal to close in the first quarter of 2026, subject to standard closing conditions that include regulatory requirements and the authorization to list the shares issued in the transaction.

What Diligent Robotics brings: Moxi and an established hospital footprint

Founded in 2017, Diligent Robotics develops Moxi, an autonomous robot designed to assist hospital staff with routine “runner” tasks, such as moving supplies, lab samples, and medications. The company has said Moxi operates in more than 25 hospital facilities in the United States and that the fleet has completed more than 1.25 million deliveries. Diligent is expected to continue operating as a subsidiary, led by co-founder and CEO Andrea Thomaz.

Completion of the transaction remains subject to customary closing conditions, including the absence of legal prohibitions and other standard provisions typically included in merger agreements.

What Serve Robotics gains: entry into indoor autonomy and higher-value service settings

Serve Robotics, based in San Francisco, is known for autonomous, low-emissions delivery robots used in last-mile logistics. The company has described its strategy as building a broader autonomy platform that can operate safely around people in complex environments. In outlining the rationale for the acquisition, Serve emphasized that hospitals offer dense, human-centric spaces with frequent “edge cases,” which can generate operational data intended to improve navigation and decision-making across robotic fleets.

The companies have also pointed to a shared technical direction: integrating autonomy and AI capabilities across both outdoor delivery routes and indoor clinical corridors, with the goal of standardizing software and operational tooling over time.

Key terms and operational details

• Purchase price: $29.0 million in Serve common stock, subject to adjustments.
• Potential earn-out: up to $5.3 million tied to milestones.
• Timing: expected to close in Q1 2026, pending standard conditions.
• Structure: Diligent to operate as a subsidiary after closing, with existing leadership continuing.

Why the transaction matters for Austin’s robotics ecosystem

Diligent Robotics has been one of Austin’s visible robotics startups focused on real-world deployment rather than lab-only demonstrations. The acquisition highlights continued consolidation in the robotics sector as companies seek established deployments, proven autonomy in difficult environments, and customers already integrating robots into daily workflows.
