Tarun Upadhyay.

Founder and CEO of Routespring

I run Routespring.

Routespring handles the parts of corporate and airline crew travel that booking systems leave behind: disruptions, hotels, payments, and reconciliation.

I write about building companies and using software when the work is still messy.

Routespring

  • Routing optimization isn't a shortest-path problem

    The hard part of flight routing was never finding the cheapest itinerary. It's that 'cheapest' and 'best' are different questions, and one of them is a hard rule while the other is a matter of taste.
