From AI to Defence: India's Deeptech Startups Are Finally Building Things That Are Hard to Copy

For most of the 2010s, India's startup story was a consumer internet story. Food delivery, ride-hailing, e-commerce, edtech — each successive wave was faster, more urban, and more dependent on aggregating demand that already existed. These were valuable businesses. They also weren't particularly hard to replicate. The moat in most of them was money: whoever could subsidise customers longest won. When the funding dried up in 2022, the cracks showed.

2026's funding activity suggests the country's startup ecosystem is quietly diversifying into something more durable.

VerveSemi, a fabless semiconductor startup, raised USD 10 million in Series A in February 2026. It builds custom chips — the same category that ISRO is trying to produce domestically, and that the global semiconductor shortage of 2021-22 made viscerally important. India currently imports most of its chips. VerveSemi is part of a small but serious group of startups that want to change that.

Articulus Surgical, backed by Kalaari Capital, works in medical robotics. This is a category where India has both the need — 1.4 billion people, a healthcare system that is chronically understaffed — and, increasingly, the engineering talent to compete. Medical robotics are not apps. They require regulatory clearance, clinical validation, hardware precision, and deep domain expertise. Companies that build in this space don't get disrupted easily.

Defence tech is attracting capital too, though founders in this space tend to be less vocal publicly. The government's push for Atmanirbhar Bharat in defence procurement, combined with the demonstrated real-world use of Indian space assets in operational contexts in 2025, has made defence-tech startups attractive to both institutional investors and the state.

Fibr AI raised USD 5.7 million in seed funding led by Accel for enterprise AI infrastructure. Mindcase secured seed funding for mental health AI. The Bengaluru-based climate-fintech firm Truboard Partners closed a Rs 20 crore round. Deepinder Goyal's new venture Temple raised USD 54 million at a USD 190 million valuation. These are not all deeptech in the strict sense, but they share a common logic: they are building infrastructure and tools that other businesses need, rather than consumer apps that users can churn out of.

This is the maturation of an ecosystem. The first generation builds consumer products. The second builds the infrastructure beneath them. India is doing the second thing now, partly because the first generation created enough talent and capital recycling to fund it, and partly because the world is actively looking for alternatives to Chinese supply chains in hardware, semiconductors, and manufacturing.

The startups building hard things in 2026 are not building for the next funding round. They are building for the next decade. That is a different kind of ambition — and a better one.
