Paul Buchheit and Sanjeev Singh are two of the most important people that the world knows nothing about. Ten years ago email used to be different. Offered by providers like Yahoo and Hotmail, it was slow, cumbersome and came with very small inboxes. Then Gmail happened. Suddenly our inboxes had gigabytes of storage in them, email got faster, mails got bunched up into conversations and email changed for ever. While Buchheit is the man who is credited with creating Gmail, Singh is generally regarded as the man who helped make that vision a reality. Singh, who has a computer science degree from Stanford University, has worked at Third Voice, the maker of the popular web annotation browser plug-in by the same name and at a US government research lab before joining Google. In 2006, along with Buchheit and others who worked on Gmail in its early days, Singh quit Google to co-found Friendfeed, a real-time feed aggregator which brings together all the updates from all of the user’s social networks, blogs and RSS feeds together to make it easier for the users to keep with the latest news. In 2009, Friendfeed was acquired by Facebook for $15 million in cash and $32 million in stock. Singh continues to work at Friendfeed.
