One-Page Plan
Updated 2026-08-22
INTRODUCTION
English translation pending.
CORE DEFINITION
A planning format, popularized in lean startup and venture pitching practice, that constrains a full business plan to one page covering the problem, solution, market, business model, team, and the specific ask. Its core proposition is that the discipline of compression exposes whether the value proposition actually holds, because vagueness cannot survive a hard space limit. The qualifier is that the page is a thinking and communication tool, not a substitute for the analysis it summarizes.
SCAFFOLDING EFFECT
Reduce cognitive load
- Slot discipline: fill six fixed slots and cap each one, so missing logic shows as an empty box. - Elevator test: read the page aloud in two minutes and cut whatever the listener does not need. - Ask clarity: state the exact request in one line, including what you want from this reader.
Anchor fast decisions
A hard space limit raises the cost of every sentence, so authors keep only claims they can defend and drop filler. Because the reader can absorb the whole argument at once, gaps in the logic become visible immediately, and the same artifact doubles as a fast alignment tool across stakeholders.
