About Rego

Helping buildings make better decisions about their materials.

Rego is a material intelligence platform for the teams responsible for buildings — facilities, sustainability, procurement, property, municipal, and operations.

Our mission

Material decisions deserve better data.

Most buildings already track energy, water, and work orders. Materials are often the missing piece. Rego exists to help organizations make better decisions about the materials flowing through their buildings. We aim to help every facility make dozens of daily decisions from what to buy, how often to haul, which vendors to trust, and where to invest in infrastructure by leveraging better data.

We built Rego because waste audits had become a one-time exercise disconnected from operations, procurement, and reporting. By turning simple photos into structured material data, we make waste audits ongoing, practical, and financially useful for the teams already managing buildings.

Why waste audits needed to change.

One-time, not ongoing

Audits used to be a snapshot. Buildings change weekly — material data should too.

Disconnected from decisions

Findings rarely reached procurement, contracts, or operations in a usable form.

Hard to scale

Spreadsheets and PDFs didn't scale across portfolios, regions, or campuses.

Why buildings need material intelligence.

Materials are a financial signal. They reveal what's being over-purchased, what's leaking through contracts, what's being hauled unnecessarily, and what could be reused or recovered. Connecting that signal to the people who make daily building decisions creates real operating leverage.

  • Procurement becomes data-driven instead of guesswork
  • Hauling schedules match actual building behavior
  • Contamination is addressed with evidence, not assumption
  • Reporting becomes a byproduct of daily work

Human expertise + AI

AI gives us speed. Experts give us trust.

Rego pairs AI-powered material analysis with human-in-the-loop review from waste experts, including TRUE-certified advisors. The combination gives teams insights they can act on with confidence — not just outputs from a black box.
