What was changed
Tiny Speck was trying to build Glitch, a quirky online game. The game did not become a durable business, but the team had built an internal messaging system that made distributed work faster.
The hard decision was to stop defending the original game and productize the tool the team actually depended on. Slack launched in 2014 as workplace communication software, with integrations and search as the wedge.
By January 2019, Slack's S-1 said daily active users exceeded 10 million, with more than 88,000 paid customers and fiscal 2019 revenue of $400.6 million.
Salesforce agreed in December 2020 to buy Slack for about $27.7 billion, turning the abandoned game infrastructure into one of enterprise software's largest collaboration platforms.
What it achieved
Slack passed 10M daily active users in early 2019 and agreed to a $27.7B sale to Salesforce in 2020.
Why it worked
The team recognized that its internal workflow solved a broader enterprise problem than the game itself.
Slack kept the product focused on habitual team communication rather than trying to relaunch another game.
The direct-listing filing gave customers confidence that a fast-growing collaboration tool had real scale.
What can be applied
A failed product can still contain the better business; preserve the working internal tool and change the market, not the team.
Aftermath
Slack became an operating unit of Salesforce after the transaction closed in 2021. The larger lesson was not that every failed consumer product has a hidden enterprise tool, but that a team should notice where users already have urgency, budget and daily repetition.
