Our Route Optimization Services

A complete API suite purpose-built for last-mile delivery — from intelligent route planning and automated dispatch to live tracking and driver assignment.

Route Optimization API

Generate dispatch-ready, multi-stop delivery routes in seconds with support for 50+ hard and soft constraints — including time windows, vehicle capacity, driver shifts, and priority stops — at predictable per-vehicle pricing.

Route Dispatch API

Automatically push optimized routes from your planning engine directly to driver apps and fleet management systems the moment planning is complete, eliminating manual handoff delays and transcription errors.

Driver Assignment API

Instantly assign drivers to delivery tasks using flexible dispatch logic, smart 1:1 matching, real-time dynamic reassignment, and advanced business rules including shift timing, order priority, and location familiarity.

Live Tracking API

Gain real-time visibility into every delivery driver's location and on-road behavior, with configurable alerts, route adherence monitoring, and live ETA recalculations fed back into your optimization workflow.

Distance Matrix API

Calculate real-time and historical travel times and ETAs between up to 5,000 origins and 5,000 destinations in a single API call — the foundational cost matrix that powers accurate route optimization at scale.

Clustering API

Pre-segment large volumes of delivery stops into geographically logical, capacity-balanced clusters before routing — reducing optimization complexity and ensuring drivers receive operationally coherent zone assignments.

Precision at Every Stop

Route Optimization Built for Last-Mile Delivery at Scale

Last-mile delivery networks face compounding complexity — dense urban stop sequences, narrow time windows, fluctuating driver availability, and customers who expect real-time visibility. NextBillion.ai's Route Optimization API is built to handle that reality, not a simplified version of it. With support for 50+ constraints, sub-second response times, and per-vehicle pricing that doesn't penalize re-optimization, delivery companies can absorb demand spikes, reduce fuel costs, and grow fulfillment capacity without growing API bills. Trusted by DoorDash, Zepto, Meesho, and 150+ businesses globally.

Co-Founder

Ajay Bulusu is a co-founder of NextBillion.ai, bringing deep expertise in geospatial technology and large-scale location platform engineering. His journey began in 2017 as part of Grab's pioneering Geo team, where he helped build the location infrastructure underpinning one of Southeast Asia's largest mobility and logistics platforms. That experience revealed how critical — and how underserved — accurate, flexible location technology was for real-world operations. Driven by a mission to democratize sophisticated location intelligence, Ajay co-launched NextBillion.ai in 2020. Under his technical leadership, the platform has scaled to serve 150+ businesses globally, optimize over 10.9 million deliveries and field tasks, and deliver more than $11 million in documented cost savings to customers.
