Private equity fund managers Orchid Asia Group and TPG have led a US$110 million Series C round for China-based marketing solutions provider Duiba. The latter helps companies obtain and manage users on their apps and designs customer loyalty programs. The company operates a software-as-a-service platform and an interactive advertising platform. Duiba plans to use the new capital for research and development, as well as to extend its services to more industries, especially ones that are traditionally offline.
