About

Built by people who understand the work.

OPEX brings together lawyers, property specialists, product leaders and software engineers with decades of experience across property, technology and enterprise software.

We built OPEX to simplify complex contract workflows, first for property project sales, and now for any organisation that needs secure, reliable e-signing.

Our story

Built in property. Expanded for business.

OPEX began with a problem we knew well: property project sales were being managed across disconnected spreadsheets, email chains, signing tools and settlement systems.

We built one platform to connect the process, from master contracts and sales advice through signing, exchange and settlement.

The proprietary e-signing technology within that platform now also powers OPEX for Business, a standalone product for organisations that need documents signed securely and efficiently.
