FTA: > In 2010, after several months of sluggish sales in and around Ontario, Mr. Wang listed the Instant Pot on Amazon, where a community of food writers eventually took notice.

Yes, but it seems as if it was starting to gather a fair bit of attention on Amazon before they sent out the test units. I suspect that the initial answer was some combination of Amazon + good product + smart positioning + good luck. Overall, it's an interesting story about a product that succeeded largely through viral marketing but I'd have liked more detail than you're likely to get from a general interest article…
I gather from some of the articles linked (http://refineandfocus.com/when-brand-communities-become-cult... and https://www.ctvnews.ca/lifestyle/from-ottawa-to-world-domina...) that unlike other past influencer marketed products, Instant Pot largely utilized Internet space: big platform social media word-of-mouth to achieve their affects. Given that Internet social media space is growing, I would expect more of these type of marketing stories in the future.
Some of it's probably the product for sure. If I remember right, rice cookers like the Zojirushi models had pretty much everything Instant Pot has, except the pressure cooking part. But that's a pretty big "except", given the dodgy past of traditional stove-top pressure cookers.
