Which business plan structure works best for a sustainable packaging startup?

[MasonC]

I'm seeking funding to scale my sustainable packaging startup and need to create a comprehensive business plan, but every template I find seems either overly simplistic or excessively detailed for a venture at my stage. I need to clearly articulate our market differentiation, financial projections, and operational roadmap to potential investors. For entrepreneurs who have successfully secured funding, which business plan template or structure did you find most effective, and what specific sections did investors focus on most during their review?

Two practical templates that work in practice: a tight 1-page plan (one-pager) and a focused 10–12 slide investor deck. Keep the sections tight: problem, your solution, market size (TAM/SAM/SOM), unit economics, go-to-market, traction, team, and the funding ask. For a sustainability startup, add a concise impact/sustainability note and a quick regulatory/compliance snapshot.
