One-page lean business plan: Lean Canvas adapted for demi-fine

## Why a one-page plan, not a thirty-page one

The traditional business plan, inherited from old-school banks and MBAs, has 30 to 80 pages, five-year projections and charts nobody revisits. In demi-fine, three things guarantee that plan becomes drawer paper: the sector shifts consumer behavior every season, real margin only appears after six months of operation, and the entrepreneur starts without a team — writing 60 pages is literally stealing time from clients.
