Chennai, India , December 15, 2025 : Chennai-based space technology startup Sisir Radar has raised $7 million in Series A funding, marking a significant milestone for India’s rapidly expanding private space sector. The funding round was led by 360 ONE Asset, with participation from strategic and institutional investors focused on deep-tech and aerospace innovation.
The fresh capital will be used to accelerate Sisir Radar’s ambitious plan to deploy India’s first privately developed L-band Synthetic Aperture Radar (SAR) satellite by 2026. Unlike conventional optical satellites, L-band SAR technology enables round-the-clock, all-weather Earth observation, allowing imaging through clouds, rain, smoke, and darkness.
Sisir Radar’s upcoming satellite is expected to serve critical sectors including defense, disaster management, agriculture, infrastructure monitoring, climate analysis, and border surveillance. The technology offers high-resolution imaging capabilities essential for real-time decision-making and national security applications.
Industry experts see the funding as a strong validation of India’s growing space-tech ecosystem, especially as policy reforms and ISRO-backed initiatives encourage private participation. With global demand for persistent Earth observation rising, Sisir Radar aims to position India as a key player in advanced radar satellite capabilities.
The development underscores India’s shift from a government-led space program to a commercially driven, innovation-focused space economy.
