Unbox Robotics Raises $28M in Series B: Autonomous Fulfilment OS With IP-Driven Swarm Robotics for Global Commerce

At 3one4 Capital, we’ve long believed that if you solve for India’s constraints – cost sensitivity, infrastructure variability, speed of deployment – you build products with global relevance. The constraint optimises the competitive advantage.

We backed Unbox Robotics early because the founding team combined full-stack technical depth with sharp market intuition. Since then, they’ve built defensible IP across India, the US, and the EU, won marquee customers globally, and assembled a world-class engineering organisation spanning fleet optimisation, safety-certified systems, and next-gen perception and navigation.

Today, we're excited to continue supporting the team as they announce a $28M Series B backed by 3one4 Capital and led by ICICI Ventures, with participation from RedStart Labs (InfoEdge), F-Prime, and existing investors.

🌍 Why this matters

Global parcel volumes are expected to cross 200 billion shipments annually by 2025, yet less than 15% of warehouses worldwide are automated. Legacy sortation systems are capital-heavy, space-inefficient, slow to deploy, and brittle in the face of demand volatility – exactly the challenges modern e-commerce and logistics operators are grappling with today.

Unbox is solving for this structural gap.

🤖 Reimagining Warehouse Automation Through Swarm Intelligence

Rather than iterating on existing conveyor architectures, the team rethought sortation from the ground up. Their breakthrough was recognizing that warehouse vertical space sits largely unused. UnboxSort deploys swarms of Autonomous Mobile Robots with scissor-lift platforms that sort parcels across multiple vertical levels, compressing the footprint by 50 to 70% while dramatically increasing throughput.

UnboxSort is a vertical sortation system that pairs compact mobile robots and modular smart racks with multi-robot control software. The platform integrates with a customer’s existing WMS or ERP through APIs, so warehouses can add automation without replacing their core systems.

The UnboxSort system architecture is built around five core components. The robot unit itself, a Multi-Robot System guided by a proprietary ACO (Ant Colony Optimization) algorithm, a Dynamic Binning module for intelligent destination assignment, Smart Racks with integrated Pick-by-Light technology, and a space efficient process layout. This integrated approach enables the system to function as a cohesive automation platform rather than isolated hardware.

Architecturally, it helps to think in two layers. A control plane that integrates with WMS and ERP, runs orchestration and operational applications, and pushes policies and live decisions. Then, an execution plane that runs real time robot control, traffic management, and rack level interactions on the warehouse floor. This separation is what enables rapid deployment, scalable throughput, and operational visibility.

⚙️ Vertical Sortation Infrastructure from First Principles

The intelligence layer is where Unbox truly stands apart. Robots operate as a coordinated swarm using ant-colony optimisation algorithms, dynamically rerouting around congestion and continuously rebalancing workloads in real time. The result: no rigid bottlenecks, no fixed infrastructure constraints.

Equally important is speed. While traditional systems take 4+ months to deploy, UnboxSort goes live in under two weeks. Warehouses can scale from 2,000 to 20,000 parcels per hour without ripping out existing infrastructure. Unbox delivers the full stack – installation, training, 24/7 support, safety, and ongoing system maintenance.

The outcomes speak for themselves:

•  99.9% sorting accuracy
•  3× improvement in workforce productivity
•  50%+ reduction in operating costs versus legacy systems

The traction is real:

•  15M+ packages processed for customers, including Inditex, DHL, Flipkart, Myntra, and Adidas
•  ⁠~5x year-on-year revenue growth with profitability
•  ⁠~96% of revenue in the last 12 months originated from Global markets

Commercially, Unbox supports both upfront sales and a Robot as a Service model (RaaS), which matters in Western markets where customers want fast time to value and the ability to scale automation as operating expense during peak demand.

Another credibility edge is localisation of core subsystems. While some components, such as optics, lidar systems, battery cells, and magnets, may still be imported, key subsystems, including motor drivers, battery packs, and control electronics, are increasingly designed in-house and manufactured locally, reinforcing Unbox’s IP-led control over performance and cost.

🚀 Backing India's Deep Tech on the World Stage

Our journey with Unbox Robotics has been deeply rewarding. What began as shared conviction around full-stack robotics built out of India has grown into a globally deployed system transforming warehouse automation across continents.

Pramod Ghadge, Shahid Memon, and Rohit Pitale, and the entire Unbox team are showing what’s possible when Indian deep-tech companies think global from day one. They are establishing new benchmarks for what logistics automation can achieve and proving it can be conceived, built, and scaled from India to serve the world’s most demanding operators.

This is how India’s robotics story gets written: Proven technical excellence meeting real market needs, competing on performance, and winning on merit.

We are proud to continue backing Unbox Robotics as it builds the autonomous fulfilment OS powering the next generation of global commerce.
