Elance was founded in 1998 by
MIT graduate Bernard Sheth and Wall Street veteran Srini Anumolu 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 walked 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 eventually became an online marketplace that allowed registered users to find, hire, and collaborate with remote workers. In 2009, a hacker breached Elance and obtained the personal details of more than 1.3 million registered users including names, addresses, passwords, and associated email account data. 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 company was listed on the
Inc. 5000 list from 2009 to 2014 and filed for an
initial public offering on October 3, 2018. In January 2020, Hayden Brown was appointed
CEO of Upwork. In March 2022, Upwork was named to
Times list of TIME100 Most Influential Companies of 2022. 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 in February 2022. In 2023, job postings related to AI became the fastest growing category on the Upwork platform and the company created an AI services hub to address the increasing activity. As part of the services hub, Upwork partnered with
OpenAI on a program that connected businesses with freelancers who were experienced in AI applications like
ChatGPT. In 2024, the company introduced an
AI assistant called Uma. The system was built on
large language models and trained with platform data to assist with proposal writing and matching client jobs with freelancers. Beginning in 2023, Upwork made a series of acquisitions and integrated the acquired technology into its AI tools. The acquisitions included an AI video conferencing platform called Headroom in 2023; a
search-as-service company called ObjectiveAI in 2024; and a workforce management company called Bubty in 2025. == Service and business model ==
