What It Was
A managed predictive-maintenance service for BC plants.
Wireless vibration sensors on their machines, monitoring and alerts handled by me.
02
How It Worked
NCD Gen4 wireless vibration sensors reported to a gateway. Node-RED and FlowFuse ran the flows, InfluxDB held the time series, and a FastAPI sidecar did the analytics.
Five analytics layers ran on top of that:
- 01ISO 20816-3 zone classification
- 02Streaming Welford z-score baselines
- 03Isolation Forest anomaly detection
- 04Trend regression
- 05Bearing fault root-cause analysis
A REGISTRY KEYED BY SENSOR MAC ADDRESS RESOLVED PER-MACHINE THRESHOLDS IN THREE TIERS.
03
Why It Died
- Small plants did not care enough to pay.
- Large plants stayed with incumbent vendors.
- Nobody hands their maintenance program to a founder with no plant-floor experience.
I pivoted to selling the analysis engine directly to analysts, which became Phasedraft.

What I Took From It
The credibility gap was the product problem, not the code. Domain trust cannot be engineered after the fact.
