Many successful businesses started with just one person who had a vision and the technical skills to deliver it to the world. Popular new sites like Techmeme, Newsblur, Instapaper and Duckduckgo started out this way which makes the costs of operating much more bearable in the beginning.
Even some of the largest companies in the world like eBay and Amazon began with one tech-savvy founder. Jeff Bezos, the founder of Amazon, was a computer engineer who decided to leave Wall Street to start an online book store out of his garage. Amazon is now the largest online retailer in the world with a revenue of $74.45 billion in 2013.
