How to Write a Business Plan (2025)

The days of 50-page business plans are over. Investors want a lean, evidence-driven document. Here's the 2025 structure.

One-page executive summary, problem & solution (validate with customer interviews), market sizing (TAM/SAM/SOM � total, serviceable, obtainable), business model (how you actually make money), traction (users, revenue, partnerships), and a 12-month financial forecast.

Skip the 5-year hockey-puck projections. Nobody believes them. Focus on unit economics: customer acquisition cost (CAC) vs. lifetime value (LTV). Show you understand the key drivers.

And please, no buzzwords. "Leveraging blockchain for synergy" = instant reject.
