The honest playbook
The 40-page business plan is a relic — here's what actually helps you start, and what you should write instead.
You're thinking about starting something. Maybe you've been thinking about it for months. And somewhere in the back of your head is this nagging idea that before you can do anything real, you need to produce a business plan — a proper one, with market analysis and five-year projections and a competitive landscape section that uses the word "synergies" at least twice.
Here's the honest answer: no, you don't. Not that kind, anyway.
The traditional business plan exists for one specific purpose: convincing a bank or investor to give you money before you've proven anything. It's a persuasion document dressed up as a strategy document. Banks wanted collateral in prose form. So entrepreneurs learned to write long.
If you're not walking into a bank this week, you don't need that document. You need something else entirely — something that helps you think clearly and move fast, not something that impresses a loan officer who will skim it anyway.
Most first-time founders spend weeks on a business plan and emerge with a beautifully formatted PDF that has never been tested against a single real human being. The market does not care about your PDF.
Before you write anything, you need to be able to answer three questions in plain English:
Who has the problem? Be specific. Not "small businesses" — that's three hundred million companies. "Freelance graphic designers who invoice clients and consistently get paid late" is a who.
What's the problem, exactly? Describe it the way the person experiencing it would describe it, not the way a consultant would. "I spend an hour every week chasing payments and it makes me feel like a debt collector instead of a creative" is a problem. "Suboptimal accounts receivable workflows" is not.
What are you offering, and why would they pay for it? One sentence. If it takes three sentences, you haven't decided yet.
Write those three answers down. That's your plan. Seriously. If you can't answer all three clearly, no amount of financial modelling will save you — and if you can answer all three clearly, you already have enough to start.
A bad plan executed is worth more than a perfect plan sitting in your Downloads folder.
Here's the thing about a business plan: it contains zero information from the real world. Every number in it is a guess. Every assumption is untested. The "market size" figure you found came from a research firm that aggregated other people's guesses.
A landing page — even a rough one — starts collecting real information the moment it goes live. Does anyone click the button? Does anyone sign up? Do people share it or ignore it? Do they email you asking a question you never anticipated?
That's signal. A business plan has no signal. It has assumptions dressed as conclusions.
You can build a basic landing page in an afternoon. It needs: a headline that states what you do, two or three sentences explaining who it's for, a clear call to action (sign up, join the waitlist, book a call — pick one), and a way for you to capture contact details. That's it. You don't need a logo. You don't need a perfect domain name. You need it to exist and to be in front of people who might care.
When someone gives you their email address for a product that doesn't exist yet, that's worth more than fifty pages of projected revenue.
I'm not saying write nothing. I'm saying write the right things — things that force real decisions rather than manufacture the appearance of certainty.
Your assumption list. Write down every assumption your business depends on being true. "People will pay £30/month for this." "Freelancers check their email daily." "The main competitor is too expensive for my target customer." Now you know what to test first. The riskiest assumption is your first experiment.
Your first 10 customers. Not a target market. Actual humans, or at least descriptions specific enough that you could find them. Where do they hang out? What do they already pay for that's adjacent to your thing? How will you reach them — not in theory, but literally, this week?
Your failure condition. What would make you conclude this specific idea isn't working? Set that bar now, before you're emotionally attached to results. "If I can't get 20 people to sign up in 6 weeks, I'll revisit the positioning" is a useful sentence. It keeps you honest.
Your revenue mechanic. How does money actually move from a customer's account to yours? What do they pay, how often, through what mechanism? If you can't describe this in two sentences, figure it out before you do anything else. Everything else is decoration.
To be fair: there are situations where a traditional business plan is genuinely required.
If you're applying for an SBA loan or a bank loan, you'll need one in their specific format — there's no way around it. If you're raising a significant seed round from institutional investors, they'll want a deck and likely a supporting document. If you're buying an existing business with external financing, same deal.
In all these cases, write the plan after you've validated the idea, not before. You'll have real numbers to put in it. That makes it more convincing anyway.
But if you're at the "should I even start this?" stage — which is probably where you are, or you wouldn't be reading this — a formal plan is just a very elaborate way to procrastinate.
Write your one-paragraph plan. List your five riskiest assumptions. Describe your first ten potential customers by name or by very specific description. Define how money gets to you. Then build the simplest possible landing page and put it in front of real people before the week is out.
That process will teach you more in ten days than a business plan would teach you in three months. And it's much harder to hide from the results.
