The AI code editor built by a company of four MIT graduates, a fork of VS Code with a model wired into every keystroke, that became the fastest-growing software product of the hype era by the numbers that were reported: a $9bn valuation in June 2025 and a figure above $29bn by that November. The record's entry for the tool that made 'vibe coding' a daily practice.
Someone remembers the tab key. Pressing it and watching the next three lines appear was, they say, the moment the job changed. The record files this under 'small keys, large consequences'.
The record notes that Cursor's success came from being an editor first and a chatbot second, and that this order was obvious in hindsight and not before.
A post in 2025 reporting that the company had passed $500m in annualised revenue with a staff in the low hundreds. The record notes that the ratio was repeated by everyone raising money that year.
Where did you see it, and when? A date and a source that still resolves.
