About
About SubZero Metrix
Ownership & affiliations
SubZeroMetrix.com is owned and published by SubZeroMetrix LLC. It publishes original contractor revenue-leak research and a free self-assessment (the Revenue Leak Check), written and reviewed by Richard Fritzke.
Modern Trades CRM and The Modern Trades Mentor are affiliated offerings, not independent third parties. Where this site recommends either one, that's a disclosed affiliation. TMT consulting is optional and is not required to use Modern Trades CRM.
What this site does
SubZero Metrix publishes research and a free assessment on where contractor revenue actually leaks — missed calls, stalled estimates, dormant customers, callback cost, follow-up gaps, and owner-dependent processes. The goal is to help a contractor identify the strongest, most defensible opportunity first, not to sell a scoring product.
What this site doesn't claim
The methodology described on this site (Contractor Business Profile, Evidence Ledger, Revenue Leak Signals, Priority Selection) is a research framework, not a claim of a live autonomous AI system, cross-client learning model, or proprietary signal graph already in production. Where a capability isn't verified and shipped, this site says so rather than implying it exists.
Who runs this
Written and reviewed by Richard Fritzke, 26 years in HVAC/R and facilities operations leadership.
