About OneMAI

At OneMAI, we are digitizing a centuries-old global tradition of community-based finance. Inspired by the worldwide practice of ROSCAs (Rotating Savings and Credit Associations), OneMAI offers a modern, secure, and transparent platform for group savings. Known by many names across the globe—Tandas (Mexico), Pandeiros (Brazil), Paluwagan (Philippines), Kye (South Korea), Hui (China), Ajo (Nigeria), Susu (Ghana), Chama (Kenya), Tanomoshi (Japan), and Kitty or Chit Funds (India)—this powerful system of collaborative saving has empowered communities for generations. OneMAI brings this trusted method into the digital age, enabling individuals, organizations, and workplaces to form automated savings circles with built-in trust, visibility, and accountability. We’re creating financial inclusion by honoring tradition—with technology. Save together. Grow together. Welcome to the future of community finance.
