Rajesh Lingappa, the chief architect of Singapore-based Bubble Motion, a Singtel Innov8 and Comcast Interactive Capital-backed social messaging company, has left to join Redmart, a Singapore-based online marketplace for household essentials.
Bubble Motion was backed by the corporate venturing unit of Singapore-based telecoms company SingTel last year in a $10m round.
Other backers of that round were Infocomm Investments, a $200m wholly-owned subsidiary of the Infocomm Development Authority of Singapore, and venture capital firms Sequoia Capital, Palomar Ventures and NGC.
Also last year, Bubble raised $6m from Palomar, Sequoia and Comcast Interactive Capital, the corporate venturing unit of US-based cable company Comcast, having closed its series B round at $14m in March 2008. Sequoia had first invested $10m in September 2006.
