Since launch, Cabbie and its paid upgrade Cabbie Pro, have been downloaded by more than 50,000 users making them some of the most popular applications in the class.

2008 – 2011 was conceived as a web-based API that would make it easy to embed content like videos, pictures, etc., from third-party sites in HTML pages. It was developed on the (then nascent) Google App Engine platform and went on to reach an average volume of nearly a million API requests per day. It was sold to Inc. in June 2011.

2008 – 2009

NextBus was a mobile web application and companion API that made it easy to track bus arrival times in Singapore. Launched in September 2008, the app received enthusiastic reception leading to wide-spread use and integration in several third-party apps.
