description: >-
  Greenfield Online, Inc. (Nasdaq SRVY) was an independent provider of Internet-based survey solutions and
  online market-research panels, headquartered in Wilton, Connecticut. Founded in 1994, it pioneered online
  panel sampling and data collection for the marketing-research industry, went public in 2004, and grew by
  acquiring sampling firms worldwide (including European comparison-shopping service Ciao). Microsoft
  acquired the company in 2008 for roughly $486 million to obtain Ciao, then divested the survey and
  sampling assets to Toluna in 2009. Greenfield Online no longer operates as an independent entity and
  publishes no developer program, public API, or live web presence today. This record is retained as a
  portfolio-lead profile surfaced from the Insight Partners portfolio.
