Slack was a failed video game — and that's the best thing that happened to it

Before Slack became the workplace tool used by millions, it was Glitch — a massively multiplayer online game that almost nobody played. The team had built an internal chat tool to coordinate game development, and when the game flopped, they realized the chat tool was the real product. Stewart Butterfield had done this before: his previous failed game became Flickr.

A pivot isn't just changing direction — it's keeping one foot planted while shifting the other. The best pivots preserve something valuable from the original attempt: the team's domain expertise, a piece of technology, or hard-won customer insights. YouTube started as a video dating site. Twitter emerged from a failed podcasting platform called Odeo. In each case, the founders didn't start from zero — they redeployed assets they'd already built.

What makes pivoting so psychologically difficult is sunk cost bias combined with identity attachment. Founders who define themselves by their original idea resist pivoting even when all signals point to failure. Research from CB Insights shows that "no market need" kills 42% of startups — many of which had viable teams and technology that could have been redirected. The founders who pivot successfully treat their original idea as a hypothesis, not a destiny.

The counterintuitive lesson: the ability to abandon your vision might be the most important founder skill. Investors increasingly look for "pivot readiness" — not because they expect failure, but because adaptability in uncertain markets is more predictive of success than any single idea.
