Jolla separates its software (Sailfish OS) and hardware businesses; Jolla Tablet could start shipping this month5
Founded in 2011 by ex-Nokia employees, Jolla is now seeing "huge opportunities in the Sailfish OS licensing business" - which probably means that various other companies will soon launch devices running Sailfish. As you may know, Sailfish OS is based on MeeGo (a now extinct software platform developed by the Linux Foundation using source code from Nokia's Maemo and Intel's Moblin).
The only Sailfish OS device that hit the market until now is the Jolla Smartphone. But the second one, the Jolla Tablet, is coming soon. Jolla raised $2.5 million via an Indiegogo campaign to launch the tablet around the world. Initially, the slate was supposed to be shipped starting June, but Jolla had to "switch to a new display" (a 7.9-inch panel with 1536 x 2048 pixels), and now the tablet is expected to start shipping in late July, or in August.
