“Can a B2B hotel-booking platform become the financial OS for corporate travel spend?”
Founded as Hotel Engine in 2018 after spinning out from Travelers Haven, focused on B2B corporate hotel booking.

In 2026 launched Engine X — a business card program powered by Stripe Issuing and Fifth Third Bank — moving from pure travel software into embedded finance / spend management. Acquisition of Options Travel signals a push into enterprise online booking tools.
