Write a Business Plan Fast

Generate a Comprehensive Business Plan in Minutes

January 05, 2026

Most entrepreneurs let great ideas die because writing a forty-page business plan feels like an impossible homework assignment.

We often have the vision mapped out, but turning it into a structured document for investors or banks is a major hurdle. I recently found a guide by a Reddit user that solves this problem. They shared a “prompt chain” that guides AI through drafting a complete business plan, section by section.

This isn’t a simple request to “write a plan.” To get a strong result, you have to break the work into logical steps. If you ask an AI to write everything at once, you usually get generic fluff.

With the structure this contributor developed, you can push the model to think about your industry, product, and financial goals. Each step feeds the next, so the plan stays consistent. That’s the difference between a coherent document and a pile of disconnected sections.

The Logic Behind the Chain
The strength of this approach is the sequence. It works like a waterfall: early outputs become the context for later sections. Here’s why the workflow holds together.

  1. Establishing the Strategic North Star
    The chain starts with an executive summary and product description. It specifically demands the “unique value proposition” and “high-level financial projections” up front. That forces the mission and core benefits to stay consistent across the entire plan.

    When the AI reaches marketing later, it can reuse the product definition it already wrote. This reduces contradictions and keeps the plan aligned. The result feels more like a single strategy than stitched-together text.

  2. Deep Market and Operational Analysis
    Most people skip operational details during brainstorming, but this chain requires them. It asks for industry trends, competitors, and even a quality control plan. It also requests an organizational structure, including advisory board members.

    That pushes the output beyond creative writing. You have to think about how you will build and run the business, not just what the idea is. It becomes a practical operating document.

  3. The Financial Reality Check
    Financial projections are often the most intimidating part. The chain asks for startup costs, monthly cash flow for the first year, and a break-even analysis. An AI can’t replace a certified accountant, but it can generate a usable framework.

    The prompt also lays out the categories you’d need in a spreadsheet, like income statements, balance sheets, and ROI. Starting from a filled-in structure saves time. It’s easier to correct numbers than invent the model from scratch.

How to Use This Prompt Chain
You can run it as manual inputs or as a single chain using tools that support automation (like Agentic Workers). The prompt uses variables such as [BUSINESS] and [INDUSTRY] that you fill in before starting. Copy the steps below and replace the bracketed sections with your details.

Step 1: Setup
Replace these variables at the very beginning:
BUSINESS: [Your Company Name]
INDUSTRY: [e.g., SaaS, Coffee Shop, E-commerce]
PRODUCT: [What you are selling]
TIMEFRAME: [e.g., 5-year projection]

Why This Matters
This removes the friction of starting. The original poster effectively gives you a consultant-style template that produces a full plan structure fast. Even if the initial numbers are wrong, you get a complete document you can edit and refine.

It turns a month-long drafting project into an afternoon of focused revision. If you want to see the original discussion or explore the tool the author mentioned, check out the link below.

Step 2: The Prompt Sequence

You can paste this entire block if your tool supports chaining, or paste it paragraph by paragraph into a standard chat interface.

Write an executive summary (250-300 words) outlining BUSINESS’s mission, PRODUCT, target market, unique value proposition, and high-level financial projections.

Provide a detailed description of PRODUCT, including its features, benefits, and how it solves customer problems. Explain its unique selling points and competitive advantages in INDUSTRY.
