Wordle: a free side project for one person that the New York Times bought

Key takeaways

Released in October 2021; 90 people played on 1 November and about 300,000 nearly two months later, per the New York Times.
The Times bought it in January 2022 for an undisclosed price 'in the low-seven figures'.
Wardle originally made it for his partner. The shareable grid of coloured squares did the marketing.

What it is

Wordle is a daily word game: you get six tries to guess a five-letter word (New York Times Company). Josh Wardle, a software engineer in Brooklyn, initially created it for his partner, a fan of word games (NPR).

What to learn

Building for one real person you know well is a valid form of validation.
Design the share artifact. If using your product produces something people want to post, you have a distribution loop.
A product without a business model can still be worth a lot to a buyer whose business model it fits.
Plan for scale stress: Wardle said "I am just one person" as the game outgrew him (NPR).

Risks and what didn't work

Wardle never monetized it himself, so the outcome depended on a single buyer; the price was only described as "low-seven figures" (New York Times Company).
He described the growth as "a little overwhelming" for one person (NPR).
Viral hits are rare and hard to repeat on purpose; treat this as an outlier, not a playbook.
