Bengaluru's reputation was built on software — the apps, the SaaS platforms, the unicorns. But behind that story, a quieter, harder-to-build wave of startups is emerging from the same city: companies building the physical technology to cut emissions, not just the code to manage them.
A new generation of "hard tech"
Unlike a typical software startup, climate tech asks founders to build things you can hold — reactors, batteries, motors, materials. Bengaluru-based Newtrace is doing exactly that in green hydrogen, having raised around $12 million across seed and pre-Series funding, and now runs a 30,000-square-foot facility staffed by more than 45 engineers and scientists. Exponent, meanwhile, has scaled its battery systems from 10 kWh packs for electric three-wheelers to 420 kWh systems built for electric buses, raising a total of $65.7 million, including a ₹200 crore round in mid-2026. Alongside them, companies like Ecozen, GPS Renewables, Chakr, and Entuple E-Mobility — the last building high-performance electric powertrains and ultra-fast EV chargers — round out a growing cluster of startups treating climate change as an engineering problem, not just a messaging one.
Solving the city's own problems first
Some of the most interesting work isn't aimed at a global market at all — it's aimed squarely at Bengaluru. The Namma Bengaluru Challenge '26, run by UnboxingBLR alongside Social Alpha and WTFund, with backing from the Government of Karnataka and the Greater Bengaluru Authority, drew nearly 600 startup applications and selected five winners to each pilot their technology across the city over six months, targeting construction, water, and waste — the categories where Bengaluru's own growth has caused the most strain. One winner, Carbon Craft Design, is reinventing building material itself, producing low-carbon blocks and panels out of industrial waste and recovered carbon.
The best climate technology doesn't ask you to change your life. It just quietly fixes the systems running underneath it.
Why the money is starting to follow
For years, climate tech in India struggled to attract capital at the scale software did. That's shifting. In just the first five months of 2026, climate technology companies in India raised roughly $791 million — and $524 million of that came from late-stage deals, a sign that investors are no longer just funding pilots and prototypes. They're backing companies with proven commercial traction, the kind Bengaluru's climate-tech cluster has spent the last several years quietly building toward.
Why this matters to us
We work at the intersection of technology, sustainability, and enterprise — which means we watch this shift closely. Bengaluru didn't become India's tech capital by accident, and the same density of engineering talent, capital, and ambition that built its software industry is now being pointed at some of the hardest physical problems the planet has. That's a story worth telling before it becomes an obvious one.
