Nimbus

Energy intelligence for commercial buildings

Confidential · Seed round · April 2026

02 · Problem

Facility teams are flying blind.

Most portfolios still reconcile utility bills by hand. By the time a spike shows up, the waste has already happened.

  • 40% of commercial energy spend is avoidable
  • Reporting for compliance takes weeks each quarter
  • Existing dashboards were built for engineers, not operators

03 · Solution

One workspace for meters, alerts, and reports.

Nimbus connects to existing BMS and utility data, then flags anomalies before they become line items.
