Your Startup Is Like a Jigsaw Puzzle. Here's How to Add New Pieces. A puzzle-loving founder on how he's kept the big picture in focus for 15 years and counting.

In a year dominated by Covid-19, stay-at-home orders fuelled worldwide demand for an unexpected item: jigsaw puzzles. The interlocking tiles were a hot commodity throughout 2020, as people of all ages sought engaging ways to pass the time.

"There's a global shortage of puzzles..," Brian Way, co-owner of Puzzle Warehouse told NPR in November. "There's not a factory on the planet that is not months behind on production."

Game manufacturer Ravensburger told CNBC that its U.S. puzzle sales were up 370% in early April, and the company expected to sell, on average, 20 puzzles per minute in North America through the end of the year. That's over 10.5 million puzzles in one region alone.
