Inrix, TOMTOM, and a couple other have been providing this data as a product for at least 2 decades. There was an early provider that lead the space, but the name of that company eludes me at the moment, may have been actually purchased by inrix.

Most of those companies focused on 10m+- resolution and focused on path data to build traffic speed data for local news companies.

Only cost a couple million bucks and an extensive partnership agreement to get into the space.

There is a lot of data washing in those agreements, mostly related to preventing reverse identification.

Airsage has taken it to the next level in the more recent past with GPS based anonymized data, but data with EXTENSIVE history. The Airsage product is zip code and smaller resolution and can provide months to years of location history of an anonymous cell phone id.
