What Heysan does

Heysan was a free mobile messaging and community based in San Francisco, California. Initially Heysan provided free messaging between phones and computers, bridging IM with SMS. The service expanded into launching a mobile community and has over 1 million users doing tens of million of monthly messages. In the summer of 2007 Heysan raised a seed round from Khosla Ventures and Atomico, the venture funds of Vinod Khosla and Niklas Zennstrom. Heysan was acquired by Good Technology in May 2009.

That does not mean they are not hiring — plenty of roles never reach a job board. The careers page below is the earliest place a new opening appears.

Check the company’s own careers page — linked at the top — before a job board. A role appears there first, sometimes weeks before it is syndicated anywhere else.
