C Combination Innovation

Two separate worlds finally connect — and the intersection is a product

One-Liner

WiFi-based continuous building compliance monitoring. Install $30 ESP32 sensors → AI creates a spatial map from WiFi signals → continuously compares to approved building plans → alerts inspectors when unauthorized changes are detected.

Kill Reason

WiFi signal-based spatial mapping does not have the precision required for building compliance enforcement, and the primary customer — municipal governments and inspectors — moves too slowly for startup sales cycles. Any IoT company can replicate the hardware stack from commodity ESP32 chips; there is no proprietary data asset that accrues over time.
