New The AI Accounting Opportunity: why now is the moment to act Read →

The defining AI companies are being built by founders nobody has heard of yet. We write their first cheque.

We back Indian founders building Global AI-native companies. We come at day zero, but stay involved longer.

Your first $1M or brutally honest feedback. Both are worth having on day zero.

First cheque

Upto $1M at pre-seed, often before incorporation, and always before the round has a lead.

Straight answers

A fast decision and honest feedback. A no from us should still be worth the meeting.

Extended team

Founding hires, first customers, pricing, positioning. We work the problem with you.

The US bridge

Warm paths into US buyers, operators and the funds that lead your next round.

Dushyant Mishra, RapidClaims

"If you're building, Day Zero's support is real — they helped us think through hiring, introduced us to customers, and stayed hands-on through follow-ups. Straight shooters, high trust."

Dushyant Mishra — Co-founder, RapidClaims
Maharishi, Supernova

"Day Zero committed before traction, and that trust has meant a lot. They go beyond capital — hiring, intros, showing up whenever needed. The most supportive partners on our cap table."

Maharishi — Co-founder, Supernova
Michael Spencer, Zeno

"Day Zero has consistently punched above their AUM weight in the value they add — thoughtful, attentive to strategic detail, and networking for us on our most pressing needs across supply chain, talent and fundraising."

Michael Spencer — Founder, Zeno
Ashish Daga, Origin

"Rahul at Day Zero was the first call for us. We whiteboarded with the team for days before zeroing in on the idea. They always felt like an extended team — they helped us hire our first engineer and made intros to the right folks in the US."

Ashish Daga — Co-founder, Origin
Why we exist

Every company has a Day Zero — the napkin, the late-night call, the decision to quit. Almost no capital shows up there.

Most investors wait for a deck, a metric, a warm intro from someone who already said yes. We think that's backwards. The most important judgement in venture is made before there is anything to judge — on the founder, the insight, and the speed at which they move.

So we operate at inception. We take the meeting early, decide fast, and give a straight answer either way. When we're in, we're an extended part of the team: first hires, first customers, and the next round.

Infrastructure gets built once. Applications get built forever.

Every platform shift follows the same curve: infrastructure, then tools, then applications — and the value settles at the top. India has always had the technical depth; paired with US market access, it compounds. We invest across three theses.
