The Verdict™ on ___ · Founder series · Prepare · By Siong Yoong
Slack began as a failed video game
Glitch, the game, died. The scrappy chat tool the team built to make it survived — and became Slack. When people can’t put a tool down, the pivot isn’t the risk. It’s the product.

a failed game / PitchScore™: a perfect Story
Illustrative read — these are teaching numbers, not a live score.
TL;DR — Slack came out of a failed game studio, and the failure was the tell, not the flaw. Founders pivot to a signal, and Slack’s was a tool the team already couldn’t put down. Read the pull, not the résumé, and a founder “starting over” can be the strongest deal in the room. Here’s how to spot it on your own.
Stewart Butterfield set out to build a game called Glitch. It flopped. But to make it, his team had built themselves a scrappy little messaging tool — and they couldn’t stop using it. That tool became Slack, one of the fastest-growing business apps ever.
Verdict Insight™
For years I watched deals like this get judged on the wrong thing. The room saw a founder whose product had died, starting over, and filed it under risk. I learned to read it the other way round — and I think you should too. Founders don’t pivot to luck. They pivot to a signal. Slack’s signal wasn’t a hunch about messaging; it was a tool the team already couldn’t work without. The dead game was just the price of finding it.
That’s the whole tell, and it is easy to miss. When the pull is that obvious — people reaching for the thing every day before anyone asked them to — the pivot stops being the risk and becomes the product. The investors who passed weren’t wrong about the game. They were reading the wrong line: the biography, not the behaviour.
How to read it on your own deals
Next time a founder in front of you is “starting over,” don’t grade the failure — find the pull. Ask what people are already doing without being told to, and whether they’d stop if the founder took it away. If it’s a tool nobody will give up, the failure behind them is a receipt, not a red flag. Read Slack that way and it comes out roughly 80/20 in its favour — not because the story was polished, but because the pull was undeniable.
