Onvia was founded in 1996 by 25-year-old Canadian entrepreneur Glenn Ballman as a one-stop shop for small business owners, initially selling over 25,000 office supplies on its website, Onvia.com. Onvia raised US $70 million in early rounds of financing, and went public on March 1, 2000 on the NASDAQ where it raised US $235 million. In August 2000 the company was awarded "Hottest Startup in Canada" by the Toronto Board of Trade and Profit Magazine. In August 2000 Onvia acquired Globe-1, a business-to-government portal, turning the company's focus away from e-commerce to the government-bid space. Onvia then used its cash reserves to buy competitors, including DemandStar in March 2001.

In 2005, Onvia released Onvia Business Builder, a tool allowing subscribers to research historical and real-time data on individual government contract opportunities Onvia continued to focus on the business to government market until the launch of their private sector tool, Onvia Planning and Construction, in February 2008. In the third quarter of 2007, Onvia reported net income for the first time, but has lost money in all but that one quarter, according to its SEC filings. Currently, Onvia's database includes over 4.5 million procurement records connected to over 275,000 companies from across 78,000 U.S. government agencies.
