ANGEL INVESTING

I back founders who ship the future.

I write small checks (USD 25K-100K) at pre-seed to seed, mostly in AI infrastructure, Web3, defence tech, and India-first climate. My biggest wins have come from backing technical founders early — Leena.ai (YC W18, $30M Series B) and BreadnPulp (acquired by Rebel Foods) are the ones I'm proudest of.

THESIS

What I back

These are the categories where I have a view and the network to be useful. Outside of them, I won't be the best investor for you.

AI infrastructure for production

Companies building the runtime, safety, observability, and deployment layers that let AI agents actually ship in production. Not demos. Production.

Web3 / DePIN / MEV mitigation

Protocols and infrastructure that make decentralised systems more practical, more fair, and more useful. Real economic activity, not yield-farming.

Defence tech (India-first)

Sovereign AI, dual-use, government procurement. India-specific opportunity with Indo-Pacific implications.

Climate / cleantech (India distribution)

Companies solving distribution and last-mile in Indian climate markets. Cleantech is finally a logistics problem.

Founders who think in systems

My best investments have been in founders who refuse to ship something they would not use themselves. Quality bar over speed bar.
