Most founders open their VC pitch with a billion-dollar TAM slide. Ajay Jain, co-founder of Silverneedle Ventures, refuses to look at it, and the bottom-up question he asks instead is the real test that decides who gets funded into his ₹800 Cr Silver X deep tech fund.

From his family's money-lending Dukan before grade two, to seven years inside Intel's pre-silicon chip verification team, to incubating 3,000 startups at T-Hub, Ajay Jain arrived at venture capital from an unconventional pipeline. As co-founder of Silverneedle Ventures and the newly launched ₹800 Cr Silver X fund, he is now betting exclusively on Indian deep tech: satellites that launch with ISRO, AI tools that automate bank compliance, brain-mapping platforms for surgical planning.

In this conversation with host Akshay Datt, Ajay unpacks why he ignores top-down TAM analysis, why most founders fail the 30 second pitch test, and why India's $12 billion RDI Scheme has rewritten the math of deep-tech investing. As global SaaS valuations compress and India's sovereign science push accelerates through 2026, this is the operating manual for how to pitch a VC in India's next venture decade.

👉Why Ajay Jain refuses to look at any startup's TAM slide and the specific bottom-up question he asks every founder instead.

👉How Silverneedle's ₹76 Cr Fund I delivered the markups, OnFinance up 5 to 8x in 18 months and Dhruva Space backed by a ₹105 Cr government grant, that justified raising an ₹800 Cr deep tech fund.

👉What the 30 second pitch test actually looks like and why most founders fail it before they even ask for money.

👉Why Ajay walked into HR tech, burned his fingers, and now uses it as a case study for why a big market alone never funds a startup.

👉How India's $12 billion RDI Scheme is rewriting the underwriting math for deep tech VCs and what it means for founders raising in 2026.
