Serve Robotics (Postmates)Creating the Future of Last-Mile Delivery

Short-distance deliveries were destroying unit economics and creating unsustainable delivery operations. Postmates faced fundamental challenges:

• Deliveries under 1 mile were unprofitable, losing money on every order because sending a car and driver for a burrito made no economic sense

• Driver churn was hitting 40% as couriers avoided short, low-paying trips, creating constant recruiting costs

• No one had built a complete product experience for autonomous delivery. How would customers receive packages from a robot? How would merchants hand off orders?

• The autonomy stack needed to work in real cities with real chaos, not just controlled environments

Pioneered the 0-1 development of autonomous sidewalk delivery, building the product and autonomy systems from the ground up:

• Autonomy product spec: Owned the Level 4 sidewalk autonomy product spec — designed the regression eval sets (per-scenario perception, planning under occlusion, novel sidewalk geometries) and the safety-critical thresholding the perception team optimized against. Owned the depot-release deployment gate: no robot left the lot until eval coverage cleared, and the operator-intervention UX caught the long-tail edge cases the model would not handle on its own. The product bar was predictable and safe over fast and clever.

• Operator platform: Designed fleet management tools enabling 1:many operator-to-robot supervision. Built remote intervention systems so one operator could monitor multiple robots across the city, making the unit economics viable.

• Customer and merchant experience: Owned the end-to-end delivery product from merchant handoff to customer unlock. Designed intuitive robot unlock flows, merchant integration workflows, and optimized every touchpoint to make autonomous delivery feel seamless and delightful.

• Delivery optimization: Redesigned the delivery experience through user research, reducing pickup time by 35% and cutting support interventions by 300%, proving the product could scale efficiently.

Built the foundational product and technology that established autonomous sidewalk delivery as a viable category:

• 0-1 Launch: Pioneered first commercial autonomous delivery robots, managing hardware partnerships and regulatory approvals to launch across 5 markets

• Delivery performance: 1,000+ autonomous deliveries proving the product and autonomy systems worked in real-world conditions

• Operational efficiency: Achieved 1:8 operator-to-robot ratios through smart fleet management, fundamentally changing the economics of last-mile delivery

• Product experience: 35% faster pickup times and 300% reduction in support interventions showed customers and merchants could trust robots

• Company impact: The product and technology foundation enabled Serve to spin out as an independent company, ultimately going public and partnering with Uber Eats for large-scale deployment
