We hate
software bloat.
We built Plenum to replace disconnected scheduling, dispatch, estimating, and customer tools.
Your business runs on precision and craftsmanship. Your software should too. Generic CRMs don't cut it. We built the operating system that HVAC operators actually want to use.
Why "Plenum"?
A plenum is the chamber in an HVAC system where air is equalized before distribution.
Without it, there is no flow. Just turbulence.
We do the same for your business. Absorb the chaos, distribute smooth flow.
Our DNA
How we think. How we build.
Speed is a Feature
If it's not instant, it's a bug. We optimize for sub-100ms interactions because waiting breaks flow.
Aligned Incentives
We build features that solve real problems, not vanity metrics. When your business runs smoother, we both win. Simple as that.
Craft Matters
Business software shouldn't look like a spreadsheet from 1995. We sweat the details because your team deserves better.
Customer Obsession
Plenum is headquartered in Denver, works remotely, and does regular contractor ride-alongs and dispatch-office research.
Deep Focus
We only serve HVAC and service trades. We don't build for e-commerce, lawyers, or dog walkers.
Built in Denver
Plenum is headquartered in Denver and works remotely while staying close to contractor workflows.
Regular contractor ride-alongs and dispatch-office research keep product decisions grounded in field work.
