We would not fit his definition of a vertical specific startup. (We have also been around a while though) The bulk of what we do is time series.
Applications we do for real paying customers include:
Detecting theft of power on the raw grid
Online payments fraud
Detecting people stealing from the telco network
Detecting faults in assembly line machines
Detecting computers about to fail
Detecting root cause of dropped calls
Kind of researchy, but we've also done robotics with RL to teach a robot to learn an obstacle course.
