How did a failed game become Slack?

The short answer

Stewart Butterfield's company built an online game called Glitch that didn't work as a business. The team kept the chat tool they had built for themselves and turned it into Slack, which had about 60,000 daily users a few months after launch.

The situation

Your online game isn't growing and you've decided to close it. There's some investor money left. Your team built a small chat tool to work together, and everyone loves it.

The options on the table

  • Give the money back to investors
  • Try one more game
  • Turn the internal chat tool into the productWhat they did
  • Sell the game's technology

What happened

Stewart Butterfield's team turned that chat tool into Slack. A few months after launch it had about 60,000 daily users and 15,000 paid seats.
