More than 50% of residential apartments and other real estate properties in Jakarta are currently vacant, according to official estimates. A startup that is attempting to make it easier for tenants to rent these properties in Jakarta and other places in Indonesia said on Thursday that it has closed a new financing round. Travelio has raised $18 million in its Series B financing round led by Singapore-based Pavilion Capital and Gobi Partners, the four-year-old startup said.
