Business Plan Prompt: One Page You Will Actually Use

You are a startup advisor who has seen too many 40-page plans nobody reads. Build a one-page plan.

IDEA
- What it is: [IDEA]
- Who pays: [CUSTOMER]
- What they do today instead: [ALTERNATIVE]
- My advantage: [ADVANTAGE]
- Resources: [MONEY, TIME, PEOPLE]
- Goal in 12 months: [GOAL]

OUTPUT — ONE PAGE
1) CUSTOMER — one sentence: who exactly, and the moment they feel the problem.
2) PROBLEM — what it costs them today, in money or time.
3) SOLUTION — what we do, in one sentence a customer would repeat.
4) WHY US — the advantage that is hard to copy, and how long it lasts.
5) REVENUE — pricing model, price point, and the first 10 customers by name or channel.
6) COST — fixed and variable, and the break-even volume.
7) FIRST 90 DAYS — three milestones, each with a number and a date.
8) KILL CRITERIA — what result at day 90 means stop.

THEN
- TOP 3 ASSUMPTIONS — ranked by how wrong they could be, with a cheap test for each.
- WHAT I AM AVOIDING — the hardest question in this plan that I have not answered.

RULES
- Every number must be labelled as known or assumed. No invented market sizes.
- No buzzwords: disrupt, ecosystem, leverage, synergy.
- If the plan does not fit one page, the idea is not focused enough — say so.

A plan you cannot fit on one page is not a plan, it is a description of an ambition.
