About DT One

DT One is a Singapore-based B2B marketplace founded in 2005 that enables businesses to deliver instant digital value to 5 billion mobile users across emerging economies. The platform consolidates a global partner network—mobile operators, digital wallets, retailers—and exposes it via a single API, allowing enterprises to offer mobile top-ups, data bundles, gaming credits, and bill-pay vouchers without navigating local compliance or technical integration separately. The 51–200 person organization is structured around sales leadership (4 roles), engineering and technology (3 roles), legal (2), and support functions, with active hiring across six countries including China, Kenya, and the UAE. Current strategic focus includes eSIM platform commercialization, regional go-to-market expansion, and reliability improvements to maintain high availability across a complex partner ecosystem.
