Why we exist

Construction in India runs on trust we never earned.

For decades, a private builder has had no way to know whether a quote is fair, whether a rate is current, or whether the person handing them a number has ever built anything. We started Projinn to fix exactly that.

The estimate shouldn't be the secret.

A typical residential project in North India moves through five parties — owner, architect, contractor, supplier, bank — and none of them share the same number. The architect's bill of quantities rarely matches the contractor's quote, the supplier's rates drift every quarter, and the bank wants a third figure to release a loan. The owner is left reconciling three documents in three languages, often after the cheque is already signed.

This isn't a software problem. It's a transparency problem. The information exists — in rate analysis registers, market surveys, and PWD schedules — it just never reaches the person paying for the build.

Every inflated quote that goes unchallenged is a tax on the family building their first home. We decided that tax should end.

Three things we refuse to compromise

Independent by design
We don't take commissions from contractors or suppliers. Our only client is the person paying for the build.
Built by QS, reviewed by PM
Every estimate is prepared by a qualified quantity surveyor and signed off by a civil project manager before it leaves our desk.
Auditable to the last rupee
Each line item traces back to a rate source — PWD, market, or negotiated — so any contractor or bank can verify it.

How Projinn started

1
A quote that didn't add up
In 2022, our founder watched his family accept a ₹2.1 Cr residential quote that a second-opinion QS later showed was inflated by 18%. There was no easy way to catch it before signing.
2
A spreadsheet that became a standard
What began as a shared rate-analysis sheet for friends grew into a six-section estimate format — summary, area, materials, labour, indirects, executive — that banks and contractors now recognise.
3
A network, not just a report
Today Projinn pairs that estimate with verified architects and contractors — so the same number that protects your budget is the one your build actually runs on.

Who we build for

Residential & commercial developers who want a defensible number before they break ground. Architects & PMCs who need a benchmark to defend their drawings. Contractors tired of quoting blind and losing bids to underpriced, unbuilt promises.

If you've ever stared at a BOQ and wondered whether the rates were real — Projinn was built for you.
