It's not that surprising when you know the history. This is the founders' second or third try at live chat with media. At Ludicorp, in the early oughts, they were building a game called Game Neverending. They built a chat feature into that game. Then they added the ability to drop photos into chat. Digital cameras and cameraphones had just become affordable, so suddenly that was the main feature of the game. Flickr had to drop the single live chat window when they became too popular, and then it became a web-based photo sharing community. But they always had plans to bring it back, they just never got around to it. Once Flickr was acquired by Yahoo those plans became even more difficult to realize. Like many companies in the middle-oughts, Flickr did everything over IRC. When they were acquired by Yahoo, most of them moved to San Francisco, but some employees never left Canada. So it was a distributed, remote workplace the entire time. It was natural to do everything over IRC and add bots and such to help you do things. When the Flickr founders left Yahoo, they founded Glitch, and it was also quite distributed, half in Vancouver, BC and half in the Bay Area. I'm not sure how they came to build their own sharing-media-in-IRC solution again, but they had the tools to hand. A fun aside: as Glitch was failing, but before they pivoted to Slack, they downsized. And a lot of those downsized employees reformed as "Tomfoolery" and created a product called "Anchor", which was basically Slack! There aren't a lot of traces that this thing ever existed but here's an article from Fast Company: https://www.fastcompany.com/3013553/meet-tomfoolery-the-company-trying-to-make-work-awesome https://www.fastcompany.com/3013553/meet-tomfoolery-the-comp... I assume that those employees realized that their internal tools were actually the best thing that they had made. Anchor was led by a former Yahoo executive who had I think been COO at Glitch. Tomfoolery/Anchor didn't get much traction and was acquihired by Yahoo just a few months later - most of those employees were ex-Yahoo anyway. A few months later Glitch pivoted to Slack and the rest is history. It's unclear to me why Tomfoolery failed when they had all the knowledge about how Glitch's Slack worked and a head start of many months. I remember a period in 2013 when a group I was involved in was choosing between Flowdock (yet another thing that was basically Slack) and Anchor and the recently-launched Slack. Anchor didn't have the rich integrations of Flowdock. Slack was very new and immature and was worse than both of them. But Slack improved faster and people like Stewart Butterfield had way more goodwill.
