Originally, Zet Universe was inspired by our founder's previous work at Microsoft (2007-2010), made in collaboration with the Office Labs and Office Labs Envisioning teams.
Between 2007 and 2009, those teams worked on many aspects of the future of Productivity, including but not limited to new device form factors (be that new phones, tablets, walls, or big desktops), new kinds of team software (precursors to Slack and Yammer, spatial environments, etc.), and so on.
Some of those ideas were released by Office Labs via the (now defunct) website officelabs.com, and experiments like "Canvas for OneNote" became truly popular among the Office power users. But, certainly, the biggest visible outcome of that work was the Productivity Future Vision video itself, shown below.
