The internet's favourite spreadsheet became a business
A shared cost-of-living tracker passed a million collaborators, then added a paid tier. It is a case study in community-first product.
Key takeaways
- A shared cost-of-living tracker spreadsheet passed a million collaborators
- The product added a paid tier after reaching scale, monetising exports and history
- Moderation stayed light-touch until scale forced more structure
Nothing about the product was novel. The distribution was: a public document that strangers could improve, with credit visible and moderation light-touch until scale forced structure.
Monetisation arrived late and narrowly — exports and history, never access to the shared data itself.
Why it matters
Creators building community products can learn from a case where open collaboration preceded monetisation. The product's success shows paid tiers can be added narrowly without restricting shared data access.
