Upwork

Elance was founded in 1998 by MIT graduate Beerud Sheth and Wall Street veteran Srini Anumolu in a two-bedroom apartment in Jersey City. In December 1999, the company's 22 employees relocated to Sunnyvale, in California's Silicon Valley. Elance's first product was the Elance Small Business Marketplace.oDesk was founded in 2003 by two friends, Odysseas Tsatalos and Stratis Karamanlakis, who wanted to work together even though one of them was in the U.S. and the other was in Greece. Originally created as a staffing firm, oDesk was eventually built into an online marketplace that allowed registered users to find, hire, and collaborate with remote workers.

Elance and oDesk announced their merger on December 18, 2013 to create Elance-oDesk. In 2015, the new company was rebranded as Upwork, which coincided with an upgrade of the oDesk platform under the same name. The newly named Upwork also planned to phase out the Elance platform within a couple of years. The Upwork platform has experienced brief outages, with one in September 2015 leading to an apology from then-CEO Stephane Kasriel.The company was listed on the Inc. 5000 list from 2009 to 2014 and filed for an initial public offering on October 3, 2018.On March 7, 2022, Upwork started suspending operations for freelancers and clients in Russia and Belarus as a sanction following Russia's invasion of Ukraine on 24 February 2022.
