The Challenge
Context: A major player in the pet care space was looking to acquire a smart-home startup. They needed to know if the tech was real or vaporware.
I was deployed to perform Technical Due Diligence. The target was a “Smart Cat Monitor”—essentially an IoT load cell platform. The challenge wasn’t building it; it was breaking it. I had to audit the mechanical architecture, firmware stability, and manufacturing readiness to determine if the valuation matched the reality.
Engineering Approach
I treated the product like a crime scene. I performed a forensic teardown and systems audit.
- Load Cell Metrology: I analyzed the strain gauge integration. Was it temperature compensated? Was the ADC resolution sufficient to detect a 4lb cat vs. a 5lb cat? (Result: The drift was significant due to poor creeping of the plastic load levers).
- Firmware Logic: I audited the sleep-wake cycles. The device claimed “1 year battery life,” but my power analysis showed it woke up for false positives (vibrations) too often, cutting real life to 3 months.
- DFM Audit: I reviewed the injection molding tool stack. The draft angles were marginal, leading to high scrape rates and cosmetic defects that would kill margins at scale.
Impact
I delivered a “Red Flag” report that reshaped the acquisition terms. The startup’s CEO later told me:
“This is more thorough than the VC vetting was…”
Project Artifacts
:::note[Findings]
- Battery Life: 3 Months (Claimed 12)
- Sensor: Strain Gauge (Uncompensated)
- Verdict: Architecture Sound, Implementation Flawed :::
