The CAA confirmed the failure of the Aberystwyth-based business, which was founded in 2009 by Angeles and Aled Rees, on Thursday (17 March).
The couple met in Argentina; Angeles, who is from Argentina, was finishing her studies as a lawyer, while Aled, who is Welsh, was travelling in Argentina.
They were inspired to launch Tango after arranging for friends and family to travel to Argentina for their wedding.
"For our wedding, 36 Welsh people came to celebrate with us in Argentina, and for our honeymoon, we organised for them all to go to Patagonia to experience the thriving Welsh culture there," they wrote on their website.
