What year was Pinterest founded?

What year was Pinterest founded? The correct answer is 2009.

Pinterest was founded in 2009 by Ben Silbermann, Paul Sciarra, and Evan Sharp. The company’s development began in December of that year, when the founders worked on the concept that would become Pinterest.

The distinction between founding and launch explains why 2010 can appear in some accounts. Pinterest’s first prototype was launched as a closed beta in March 2010, initially for a small group of colleagues and family members. The service then expanded gradually before becoming more widely available.

Pinterest’s public product history therefore spans both years: the company and core concept date to 2009, while the first prototype and early service launch occurred in 2010. The answer 2011 is later than the launch period, and 2012 was the year Pinterest opened more broadly and introduced business accounts, not the founding year.
