About Proanex

Making property decisions easier to defend.

Proanex Ltd is a UK technology company. We build software that helps investors, lenders and advisers understand residential property, and show their working when they do.

Our mission

To make the UK property market more transparent, by making every number in it traceable.

The UK publishes an extraordinary amount of property data: every sale, every energy certificate, every planning constraint. But it is scattered, inconsistent and hard to use, so decisions worth millions still rest on spreadsheets and instinct.

Proanex was founded to close that gap. We bring the records together, attach them to the property they describe, run the calculations in code you can audit, and use AI only to explain what the evidence already shows.

What we value

How we work.

Evidence first

If we can't show where a number came from, we don't show the number.

Plain about uncertainty

Ranges, confidence levels and withheld figures are features, not failures.

Careful with data

We respect licences, keep customer data private to them, and collect as little as we need.

People decide

Our software finds, calculates and explains. Decisions, offers and advice stay with people.
