We started an ESP32-based design but for internal R&D purposes, within our inkjet manufacturing division. In that sense it's not commercial but uses professional toolsets and contract manufacturing etc., assurance of supply and supply chains. In the past we mainly used STM32 both because it's a great chip and because we have a tight relationship with ST. However, some of the younger employees we recently brought on are big fans of the ESP32 and we thought "why not give the youngsters a chance". It's looking really promising, the ESP32 nicely fills the niche between low-level Arduino-like micros and Linux-based larger boards like the Pi.
