Fourzip Fleet Tracking

Built custom GPS tracking hardware at ₹700 when the market charged ₹4,000. Tracked 10,000+ vehicles with an RTOS-based device we designed from scratch. Bootstrapped the company from 4 people in a professor's basement to 30.

☕ The Order

GPS tracking was a racket

In 2015, fleet tracking in India was broken. The hardware was expensive (₹4,000+ per device), inflexible, and locked you into the vendor's ecosystem. Chinese devices from GT06 and Teltonika lacked customization. Indian vendors like Itriangle weren't much better.

If you wanted multi-sensor support — temperature, fuel, RFID, cameras — you were looking at ₹8,000-10,000 per device. For a small transporter with 200 trucks, that's ₹20 lakh just for hardware. Before software, before servers, before anything useful.

We started in our professor's basement while our classmates took safe TCS and Infosys jobs. We figured if the hardware was the bottleneck, we'd build the hardware.

🔥 The Brew

If you can't buy it, build it

We didn't just build software on top of existing hardware — we built the entire stack from the ground up.

→ Custom RTOS-based device: Wrote custom firmware scripts for a GPS device that cost ₹700 to manufacture. Same capabilities as ₹4,000 alternatives. Significantly cheaper with better customization.

→ Multi-sensor architecture: Temperature sensors for cold chain, fuel sensors for pilferage detection, RFID for student safety, cameras for security. One device platform, many use cases.

→ MQTT-based infrastructure: Real-time data pipeline handling thousands of concurrent device connections. Route replay, geofencing, proactive alerts.

→ Diversified verticals: From garbage trucks (Ulhasnagar Municipality) to police vehicles (Vijayawada Government) to ammonium nitrate trucks (Deepak Fertiliser) to school buses (RFID + cameras). Each vertical taught us something new.

→ Bootstrapped growth: Started with 4 co-founders. No funding. Grew to 30 people purely on revenue. Every feature was driven by a paying customer's real need.

✨ The Serve

The Results

10,000+ Vehicles tracked

₹700 Per device cost

82% Cost reduction vs market

30 Team grown from 4

6+ Verticals served

7 years Bootstrapped operation

Fourzip taught me everything I know about building under constraints. When you can't outspend the competition, you outbuild them. When the market charges ₹4,000, you figure out how to do it for ₹700.

We served government bodies, corporate fleets, school buses, and cold chain logistics — all from the same platform we built in a basement. That resourcefulness is baked into everything I build today.
