I think you actually answered my question. I was not 100% sure if there is no VC money for a company that solves some verticals with STAN. I assume there are still some quant companies out there using some flavor of HMMs.

But yes, the question may be phrased a bit poorly. Are people still using probabilistic graphical models without deep learning as their go-to model in startups in some verticals? What verticals would that be? And if there is no VC money for this? What are they actually doing? Some combination of PGMs with deep neural network nodes?
