## Summary

Indian defense startup developing 6-month endurance stratospheric drones (HAPS) at 60,000-70,000 ft for ISR and communications; $2.6M revenue with Indian Armed Forces contracts at $1-2M versus $100M+ satellite cost.

## Company Overview

Kalam Labs is a Bengaluru-based defense technology startup developing autonomous stratospheric drones and High-Altitude Pseudo-Satellites (HAPS) that operate at 60,000-70,000 feet altitude with endurance of up to 6 months — providing persistent intelligence, surveillance, and reconnaissance (ISR) and communications relay services for military and government applications at a fraction of the cost of traditional satellites. A Y Combinator W21 graduate, Kalam Labs raised $2 million in funding, achieved $2.6 million in annual revenue as of December 2024, and secured contracts with the Indian Armed Forces and Ministry of Defence.

Kalam Labs' stratospheric drone platform occupies a unique niche between traditional drones (which operate below 20,000 feet and have limited endurance) and satellites (which provide global coverage but cost $100 million+ to build and launch). At 60,000-70,000 feet, Kalam's HAPS drones fly above commercial air traffic, above weather, and below satellite orbit — providing persistent wide-area coverage of a specific geographic region for months at a time. The system costs $1-2 million versus $100+ million for a satellite, making persistent area surveillance economically accessible for military applications like border monitoring, maritime surveillance, and ISR in contested zones.

In 2025, Kalam Labs competes in the stratospheric UAV and HAPS market with Airbus's Zephyr (the leading commercial HAPS platform, solar-powered), SoftBank's HAPSMobile (StratosBus), and Vanilla Aircraft (long-endurance ISR drones) for high-altitude persistent surveillance and communications relay. The Indian defense market is a priority for Kalam — India's border challenges with China and Pakistan create demand for persistent ISR capability that traditional satellite programs can't fulfill at the response speeds India needs. The Indian Armed Forces contracts validate the platform's military readiness. The 2025 strategy focuses on growing the Indian defense contract base, developing the communications relay use case (providing internet connectivity to rural or maritime areas), and expanding to allied defense customers in Southeast Asia.
