Could you build this?
No Developing custom firmware, device drivers, low-power e-ink display refresh waveforms, and ad-hoc peer-to-peer wireless networking across embedded hardware targets requires specialized embedded systems engineering.
What it would actually take: Requires writing embedded C/C++ or Rust firmware targeting ESP32 or similar microcontrollers, interfacing directly with SPI/I2C e-paper controllers and managing custom LUT refresh waveforms to mitigate ghosting. P2P discovery requires raw ESP-NOW or Bluetooth LE mesh protocols with zero-config state synchronization. Deep embedded systems, microcontroller peripheral driver development, and hardware debugging skills are essential.

Nobody's really built a vertical saas tool for Insurance yet.
