One of the biggest events in startup funding in India this week: Zetwerk Manufacturing Business's $518 million (₹5,012.33 crore) IPO was fully subscribed on the last day of bidding on Monday, October 19, exchange data showed — a last-minute save led entirely by institutional demand.

The issue received bids for 220.4 million shares against 185.1 million shares on offer (as of 2:00 pm IST). But the mix was lopsided: qualified institutional buyers (QIBs) bid for 1.63 times their quota, while non-institutional investors and retail managed only 0.79 times and 0.51 times respectively.

The Peak XV Partners- and Accel India-backed contract manufacturer is seeking a valuation of up to ₹255.83 billion ($2.69 billion) at the top of its ₹143–151 price band. Last week it raised ₹22.51 billion from anchor investors — including Capital Group, BlackRock and Goldman Sachs — across 99 investors, which anchored the deal. The IPO combines a ₹28.3 billion fresh issue with an offer for sale of 144.53 million shares by existing investors.

The sellers tell their own story: co-founders Amrit Acharya and Srinath Ramakkrushnan and Creovate Innovation are parting with 51.4 million shares, while Peak XV Partners, Lightspeed and Accel India are trimming holdings. Proceeds will go to prepay borrowings and fund inorganic growth. Zetwerk counts Siemens Gamesa, Acer India, NTPC Renewable Energy and the Indian Air Force among its major clients. The stock is expected to begin trading on October 23.

Why it matters for founders

An IPO can clear the line on QIB demand alone while retail sits out — the anchor book did the heavy lifting weeks before the public bid. Founders eyeing public markets: courting long-only institutional capital early matters more than day-one retail buzz.
