With our internal team, we’ve managed to create a killer backend that would do all the hard routing stuff without issues. It was better than Google Maps in most cases!
Now, we just needed the app. We used all our money to pay a third party contractor to make the app, and they failed miserably. We never received a working prototype. We ran out of gas.
The backend still exists, in case anyone wants to give the app a shot. I might release the backend as open source. Ping me if this interests you.
