Ex-ISRO scientist's SpectraGaze raises Rs 3.7 crore for satellite imaging sensors

SpectraGaze Systems, an Ahmedabad start-up that builds optical imaging sensors for satellites and defence systems, has raised Rs 3.7 crore in a seed funding round led by venture capital firm GVFL, with angel investors also taking part, according to reports on October 23, 2026. It is the company's first outside funding: it was founded in 2023 by Arup Banerjee, a former scientist at the Indian Space Research Organisation (ISRO) with 23 years of experience, and has grown so far on money from customers. The company says its customers include ISRO, the Physical Research Laboratory and Kaynes Technology.

A satellite is only as useful as what it can see. The camera or sensor it carries, called the payload, decides whether it can map crops, track ships, watch borders or study the atmosphere. For decades, India's space payloads were built mainly inside ISRO and its labs. As India opens its space sector to private companies, small specialist firms that can design and build such instruments are becoming an important part of the supply chain.

SpectraGaze is an example of a pattern now common in Indian deep tech: an experienced government scientist leaves to start a company, wins work from the same institutions first, and only then raises venture money. Growing on customer revenue for three years before seeking outside funding is unusual among start-ups and shows that the firm had paying customers before investors came in.

Electro-optical payloads use light, visible or infrared, to form images. One instrument mentioned in reports is a hyperspectral camera for a small "3U" satellite, a small standard-size class of CubeSat. A hyperspectral camera splits light into many narrow colour bands, which lets analysts identify materials, crop health or pollution in ways an ordinary camera cannot. Reports differ on when this camera will be delivered, so no date is given here.

For India, home-grown imaging hardware matters for both cost and security. Space and defence buyers often prefer suppliers inside the country for sensitive equipment, and domestic designs can reduce dependence on imported sensors. The seed round is small, but it is aimed at the slow, hardware-heavy work, testing infrastructure and engineering staff, that such products need.

The company's claims about its products and customers are its own; the round size and investors are as reported by several outlets.

Short-term: The money lets SpectraGaze hire engineers, upgrade its test facilities and deliver on existing orders from space and defence customers.

Long-term: If it scales, the company could become one of a growing group of Indian private suppliers of satellite payloads, supporting the government's push for a larger private role in space.

Who is affected: Indian space and defence agencies and their contractors, engineers in the space sector, other space-tech start-ups seeking funding, and investors in deep technology.
