I really hope one day one of these city transport organisations either buy it out, push for it, or license their tech.
Now that the MTA app is so good and has achieved feature parity with Citymapper, I prefer that for 90% of the time. It doesn't have multi-modal (eg subway + citibike) and doesn't show estimates of uber/lyft prices, but those have not been very useful in my experience.
Citymapper is still ok to quickly check upcoming train or bus departures.
Knowing how they are using the data from citymapper, I've since uninstalled it.
Via is primarily SaaS where their customers are cities themselves to help digitize and optimize their public transit networks. You might be thinking of: at one point in time and in some places, Via operated ride shares, but that's not their main business and they discontinued much of that during the pandemic.
The citymapper acquisition notes really fit Via's strategy of being able to help cities unify and optimize transit infrastructure.
