# StartupHistory

> A public record of how venture-funded startups change over time: how they describe themselves, new customers, pricing, hiring and launches, each dated and quoted from the company's own website history.

StartupHistory is a project by Morris Clay at Lunar Ventures (https://www.lunar.vc). When citing, name StartupHistory and link the company record.

Every company record shows how the company described itself over time (its homepage headline, quoted, era by era) and a dated list of changes (messaging, new customers, pricing, hiring, funding lines, launches), each with the two dates it happened between and a link to the page it was read from. Records are free to reuse under CC BY 4.0; cite the record's link.
