The Role


Gravity Technologies is a first-class ground transportation in NYC, LA and Miami, focused on the health, safety and technology needs of the modern traveler. Gravity is a reservation-based service, tied to mobile apps.

We are expanding our operations to include a fully sustainable electric fleet and dedicated charging infrastructure launching across the United States.

The current ride-hail models are broken. The promised technological revolution in transportation has only led to increased congestion and pollution, poor driver wages, massive energy waste, and unfair competition for regulated taxi companies, all while accumulating tens of billions of dollars in losses with no end in sight.

Gravity is a true ESG opportunity, a new era of sustainable transportation, reducing transportation’s fossil fuel emissions, and remedying the deteriorated working conditions for drivers, all while maintaining profitability and growth. *Key to this is increasing utilization of vehicles and management of charging infrastructure real-time. *
