What this cluster makes
The OMR corridor is the state's services engine — IT services, global capability centres and a widening band of engineering-R&D captives. It does not appear in any industrial land dataset because its unit of production is a floor of a building, not an acre of a park, which is exactly why the estate under-counts it.
Output, ₹'000 crore
Unit: ₹'000 cr

Value shown is announced ₹, narrowing as commitments progress. The announced-to-deployed discount is 60–80% C and is applied to every headline figure on this platform.
Workforce and skills
An English-fluent graduate pipeline from across the state and beyond; attrition, not supply, is the operative number.
The constraint
Commute time and residential water on the OMR corridor cap effective floor utilisation; flooding risk on the ECR approaches recurs.
This is the section a promotion agency cannot write. An evidence institution must — and that asymmetry is the entire licence to operate.
Method and sources
Every figure on this page carries its own confidence tag and as-at date. Firm counts derive from the MCA GODL layer with Arivu curation; output and employment are structured from the DES Annual Survey; commitments are traced from public releases and company filings, with the 60–80% announced-to-deployed discount applied. All figures on this preview are illustrative.
Announced to date: ₹5,600 crore across 2 tracked commitments.
