Paul Appleton, managing partner at chartered accountants and insolvency specialists David Rubin & Partners, had been appointed liquidator earlier this month. However, it is thought a buyer could not be found.
In a statement, Appleton told Media Week: "Joost UK Limited was the UK trading company for the Joost group. The latter operates Joost.com. When Joost UK entered into liquidation, there were relatively few trade creditors. Users of Joost.com are unaffected by this change."
Joost declined to comment.
The closure of its UK operation marks a major retreat by the company as competition in the VoD market hots up. Hulu, the US VoD service owned by Disney, News Corp and NBC Universal, is planning a UK launch, while YouTube plans to introduce a long-form video presence in the forthcoming months.
In July, Joost dropped its consumer video focus and parted company with its high-profile chief executive, Mike Volpi, as it revealed plans to reinvent itself as a white-label platform for cable and satellite broadcasters.
It said its portal would remain open, but would instead focus on providing "end-to-end, cost-effective video for media companies" around the world that are embracing online video and looking to build a branded experience for their content.
Joost was founded by Janus Friis and Niklas Zennstrom in 2007. However, it struggled to take off, with the service requiring users to download the Joost player to watch videos rather than streaming video.
