When every second counts, your routing engine cannot afford to fail. NextBillion.ai's Route Optimization API is purpose-built for emergency response operations — delivering sub-second dispatch-ready routes, real-time dynamic rerouting, and 50+ constraint support so your teams reach critical locations faster, smarter, and without on-road surprises.
A complete API suite engineered for time-critical emergency response dispatch, routing, and fleet coordination at scale.
Generate dispatch-ready, multi-stop emergency response routes in seconds with 50+ hard and soft constraints — including vehicle type, shift windows, priority stops, and regulatory compliance — ensuring the fastest, safest path every time.
Instantly match emergency units to incidents using dynamic parameters including proximity, availability, shift timing, and location familiarity — enabling smart 1:1 dispatch and real-time reassignment when situations evolve.
Maintain sub-meter real-time visibility over every emergency vehicle and field unit, with configurable alerts for route deviation, idle time, and boundary events — keeping dispatchers informed and in control throughout every response.
Define dynamic operational zones, incident perimeters, and restricted areas that automatically trigger real-time alerts and route adjustments — ensuring vehicles never enter unsafe or compliance-sensitive boundaries during active responses.
Deliver precise, vehicle-specific turn-by-turn navigation to emergency response drivers with real-time and historical traffic intelligence, custom road attribute overrides, and departure-time routing for scheduled and on-demand missions.
Automate the handoff from optimized route planning to on-road execution — pushing updated dispatch instructions to driver apps and fleet systems in real time, eliminating manual delays and errors during time-critical incident response.
Emergency response operations cannot tolerate routing engines built for parcel delivery. NextBillion.ai's Route Optimization API is engineered for the highest-stakes dispatch environments — processing priority incident assignments, vehicle-specific road constraints, and real-time rerouting around closures or restricted zones in under a second. With 50+ configurable constraints, custom road attribute overrides via the Road Editor App, and predictable per-vehicle pricing that scales with your fleet rather than your call volume, your operation gets enterprise-grade routing intelligence without the cost unpredictability of legacy mapping APIs.

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.
Co-Founder
Gaurav Bubna drives product innovation at NextBillion.ai, bringing a proven track record of building successful products from scratch across ride-hailing, food delivery, and logistics. Before co-founding NextBillion.ai, Gaurav held product leadership roles at Grab, Ola, and Morgan Stanley — organizations where location technology and operational efficiency are existential. His time on Grab's Geo team alongside Ajay and Shaolin crystallized the vision: logistics and field service businesses needed enterprise-grade location intelligence without prohibitive per-call pricing. Since launching NextBillion.ai in 2020, Gaurav has led the product evolution that has helped the platform navigate over 557 million miles and raise $34.25M in venture capital from investors including Lightspeed and Microsoft's M12.
Co-Founder
Shaolin Zheng is a co-founder of NextBillion.ai, contributing deep technical expertise in geospatial systems and scalable mapping infrastructure. Like his co-founders, Shaolin's formative experience building location technology for Grab's Geo team gave him firsthand insight into the operational gaps that generic mapping solutions leave unaddressed — particularly for field service and logistics businesses operating at scale. His engineering perspective shapes NextBillion.ai's core philosophy: location technology must be customizable, cost-predictable, and production-reliable. The platform he helped build now powers GPS tracking, route optimization, and field service intelligence for over 150 businesses worldwide, with on-premise deployment options and SOC 2 Type II and ISO/IEC 27001:2013 certifications ensuring enterprise-grade security.
The Route Optimization API delivers dispatch-ready routes in sub-second response times, even when processing complex multi-unit scenarios with 50+ constraints applied. The low-latency endpoint is engineered for high-throughput production environments, meaning incident assignments and route calculations complete fast enough to keep pace with real-time emergency response workflows without introducing operational delay.
