About Us

Sigma Limited is a Hong Kong company specializing in mobile applications, primary in advertising, marketing, and customer relationship management (CRM).

Our main development office is located at 61 Kai Tin Road, Lam Tin, Kowloon, Hong Kong. We also have an office in North America in Chevy Chase, Maryland, a suburb of Washington, DC.

The founders of Sigma Limited have been working in mobile phone advertising for ten years. Their experience goes back to the design and implementation of one of the first mobile advertising platforms in the world, an ad-before-call platform that provided subsidized calling services for subscribers in Hong Kong, Singapore, and Paris. The core team at Sigma created the basic architecture for that system and led the implementation of advertising platform as well as the integration of the IVRs with the operator's pre-pay platform and the generation of CDRs for the operator's billing system.

The core team has additional management and engineering experience in streaming video advertising for both mobile and non-mobile services. We are combining that experience with the unique capabilities of our video streaming partner, Dao Laboratory, to create a mobile video platform offering seamless transitions, highly detailed reporting, simple user response handling, and flexible content and stream management.
