Here's the first thing to know about writing a business plan for investors: most of them will not read it. Not cover to cover. They'll read the deck, then the numbers, then the one paragraph in the plan that explains whatever confused them in the deck. Write for that reader. Not the one you wish you had.
I've been on both sides of this. I wrote the plans that raised the money for Flashline, which sold to BEA Systems for $55 million in 2006. I've read a great many since, as an accelerator operator and an investor. The difference between a plan that gets funded and one that doesn't is rarely the idea. It's the evidence, and how fast the reader can find it.
Two plans, not one
The plan you run the company on is long. It has to be. It holds the hiring sequence, the pricing experiments, the reasons you killed feature four. Keep that document. Do not send it to anyone.
The plan for investors is a compression. Ten to fifteen pages if it's prose, and most of the value sits in about three of them. Its job is to make a stranger believe six specific things in twenty minutes. Everything that doesn't serve one of the six is weight.
The six things
They map to the top of the rubric I use to score plans. The ranking matters more than the definitions.
First, that you're the right people. Not good people. The right ones for this problem: you've lived it or shipped in it, you can build and sell it, and you know which gaps you haven't filled. Investors fund people who are unusually suited to a specific problem. Plans rarely fake this well, so don't try.
Second, that someone wants this. Revenue if you have it. Retained users, signed pilots, or a waitlist that converts if you don't. "Interest" is the bottom rung of the proof ladder. Most plans claim it and hope you read it as revenue.
Third, that the problem hurts. Who exactly, how often, and what it costs them. A painkiller, not a vitamin.
Fourth, that the market is real and the timing is now. Bottom-up reasoning about who you can reach, and a sharp answer to "why now." A spreadsheet TAM is not knowledge. It's arithmetic wearing a suit.
Fifth, how you make money and whether the unit economics work directionally. Directionally is the word. Nobody expects a seed-stage lifetime value to three decimal places. The plans that arrive with three decimals get read more suspiciously, not less.
Sixth, what the money buys. The ask, tied to the milestones it funds and the runway it delivers. A round number with no plan behind it is a finding, not a formality.
The numbers have to agree with each other
This is where most investor plans die, and it's rarely the size of the opportunity. It's the market slide that doesn't match the go-to-market. The projections that don't match the pricing. The pipeline figure on page four that's three times the pipeline figure on page nine.
One of the five red-flag gates in my rubric is "numbers don't reconcile." It fires more than any other. A plan whose numbers argue with each other reads as either careless or creative. Neither raises money.
Before you send anything, read it as an adversary. Find every number. Check that each one agrees with every other number in the document. It's tedious. It's also the highest-return hour in the whole process.
What to leave out
Cut the history of the industry. They know it, or they don't care. Cut the competitor matrix with your column full of green checkmarks. Nobody has ever believed one. Cut the "exit strategy" section. If the business works, the exits show up on their own, and naming an acquirer you've never spoken to is a small confession. Cut the adjectives. "Disruptive," "world-class," and "best-in-class" have never moved an investor one inch.
Current view, subject to change
I think the plan matters less than it used to and the evidence inside it matters more. Ten years ago the plan was the artifact. Now it's the appendix to the deck and the data room. I'd revise that if I saw investors going back to long-form plans as a primary read. I haven't.
Final thoughts
A business plan for investors isn't a story you tell well. It's a set of claims you can back, arranged so a busy stranger finds the backing fast. Write the long version for yourself. Send the short version to them. Make sure every number in it has met every other number.
If you want to know how yours reads against the six things above before an investor tells you, Alex, the managed agent we built at Coworkers.Global, scores it on this rubric and names the weakest part first. Every plan gets a free screen. Drop it at coworkers.global/ai-business-plan-review.
