The most common reasons
  • 4Winning a customer costs more than the customer pays.Dropshipping, print on demand, a mobile app, an online course
  • 4The money runs out before break-even, or never reaches a salary.A café, a gym, a YouTube channel, a paid newsletter
  • 3A legal risk bigger than the whole budget.Dropshipping, print on demand, a paid community
  • 2Not enough hours in the week.A side-project SaaS, an Etsy shop

Some plans fail for more than one reason. These are the questions a friendly chatbot rarely asks, and the ones Crosscheck is built to push on.

AI is free.
A plan you can trust isn't.

Free chatbots are built to be helpful and agreeable. They'll write you a confident plan in seconds, and nobody checks a word of it. If one number is wrong, you find out when it's your money. So we set two of the best AI models against each other and built Crosscheck, the software that referees them. It fixes every mistake they catch and flags anything that can't be proven before you ever see it.

A specialist, not a chatbot

Free AI does everything. We do one thing.

Chatbots write poems, recipes, emails and homework. They're good at a little of everything. HaveTheIdea does one job only: tell you whether your business idea will work, and exactly what to do next. Everything we've built is for that one job.

Why you can trust it

Every AI makes mistakes. Ours get caught.

Even the best AI sometimes gets things wrong, and says it confidently. That's why we never trust just one. Before your plan reaches you, Crosscheck has a rival AI, from a different company, attack every page and looks for four kinds of mistake:

  • Numbers that don't matchA price, budget or date that doesn't match the rest of your plan.
  • The wrong country's rulesA law, licence, tax or office from somewhere you don't operate.
  • Parts that disagreeTwo chapters that can't both be true.
  • Confident guessesExact fees or deadlines stated as fact with nothing to back them up.
Crosscheck · Plan #01423 found · 2 fixed · 1 flagged
Chapter 6 · numbers don't match Start-up budget A$16,500. The rest of the plan says A$9,400. Fixed to A$9,400 and checked again.
Chapter 12 · wrong country "Register with the UK tax office" for a business in Australia. Fixed to the ATO and checked again.
Chapter 14 · no source An exact council permit fee, with nothing to back it up. Couldn't be confirmed, so it's flagged for you to check.
illustration. in your plan, flagged points appear right under the chapter, on screen and in the PDF.
What you get: 16 chapters

One plan. Every answer you need.

Part 1 · The verdict

Should you do it?

A clear score and verdict that can say "don't" (with a better idea to try instead), a cheap way to test it for under €100, who your customers are, and who you're up against.

Part 2 · The money

Will it make money?

How you'll make money, what it costs to start and when you break even, the smallest version you can sell first, how to get your first customers, and what to charge.

Part 3 · The rules & first steps

What do you do first?

Registering the business, tax and invoices for your country, the rules you must follow, the risks most likely to sink it, and a step-by-step 30/60/90-day plan.

Twenty real reports · unedited

Honest enough to publish a "Don't do this."

Every report we publish is complete, including the ones where the answer is no. Eight of the twenty say the plan works. Twelve say it doesn't, and explain why.

Promising · 7/10

Going freelance · UK

A data engineer leaving a £68,000 job with two clients already signed. The taxes, the paperwork, and the day rate you actually need once you count the days you can't bill.

Risky · 5/10

Print on demand · US

Shirts for emergency-room nurses on $1,500. The margin is real: $8.25 a tee. Getting each customer costs $20 to $40. That's the whole report in one line.

Dropshipping · UK

The advertising costs more than the product earns, and UK law makes you responsible for goods you never touch. We published it anyway. That's the point.

Before you ask

The honest answers.

AI is free. Why would I pay?
Because free AI gives you one unchecked answer, and you're the one who has to find the mistakes, usually after they've cost you money. HaveTheIdea sets two of the world's best AI models, from rival companies, against each other, and our own software, Crosscheck, referees them. One writes your plan from official government sources, another hunts for its mistakes, and what it finds gets fixed and checked again, or flagged so you know. You also don't need to know what to ask: answer five simple questions and get a complete 16-chapter plan and PDF. And if it isn't worth it, you get your money back.
Can't I just ask ChatGPT for a business plan?
You can, and for brainstorming it's great. But a chatbot gives you one confident answer that nobody checks, and it doesn't know which rules, taxes and licences apply where you live unless you already know what to ask. HaveTheIdea researches official government websites live while it writes, then a second top AI from a different company goes through every chapter for wrong numbers, wrong-country rules and contradictions. What it can't confirm is flagged for you, not hidden. Try the live debate above and see the checker push back.
Is the debate on this page real?
Yes. When you type an idea, two real AI models from two different companies answer right then: one gives a quick verdict, the other checks it. It's a short first take. The full plan goes much deeper: 16 chapters, live research on official websites, and a check of every chapter.
Can I ask it anything?
No, and that's on purpose. HaveTheIdea does one thing: it checks a business idea and gives you a complete plan for it. Because it only does that, every part of it (the questions, the sources, the verdict and the checks) is built for that one job. For anything else, a general chatbot is fine.
Which AIs do you use?
Two of the latest top models, always from rival companies, so they don't share the same blind spots. Our own software, Crosscheck, sets them against each other on every chapter: one writes, the other attacks, and Crosscheck fixes or flags what they find. When a better model comes out, we switch to it. The companies that currently process your answers are listed in our privacy policy.
Will it just tell me my idea is great?
No, and that's the whole point. The verdict goes from "Strong" all the way down to "Don't do this", and we judge the idea as written, not the dream version. When the news is bad, you also get a better version of your idea that could work. Of the twenty reports we publish, twelve say the plan doesn't work as written. You can read every one.
How do I know the facts are right?
Your plan is written from official government and regulator websites. The chapters on rules, tax, compliance, your market and competitors also research the web live while they're written, and every fact taken from a page links to that exact page. Links are checked before you get your plan, and broken ones are removed. Then Crosscheck has a rival AI go through every page for wrong numbers, wrong-country rules and guesses stated as facts. Anything without a source is labelled as an estimate, so you always know what to double-check. Rules change over time, so treat your plan as today's map, not a permanent one.
Is this legal or tax advice?
No, and we'd never pretend otherwise. It's research: a clear, sourced map of what applies to you and what to confirm. For binding decisions, take it to a licensed professional. You'll walk in already knowing the right questions.
Is there a person writing this?
No. HaveTheIdea is fully automated. You answer five questions, the AIs write and check your plan, and minutes later it's ready. No consultant, no meetings. That's why it costs US$29 instead of thousands.
Which countries does it work for?
Any country. You choose from 240+ countries and territories, and your plan can be written in any of 34 languages, including English, Spanish, German, French, Portuguese, Arabic, Hindi, Japanese and Chinese. While it writes, the AI researches the official government and regulator websites for your country live. Our deepest pre-collected official sources cover Australia, the EU, the UK, the US and Czechia, and we keep adding more.
What if my business is in more than one country?
That's fine. Your plan is built around wherever you operate or sell, and it's written in your language. Our official sources are deepest for Australia, the EU, the UK, the US and Czechia, and we keep adding more.
What if it's not useful?
Read the free sample first. That's what it's for. The full plan also comes with a 14-day money-back guarantee. One-time price, no subscription, ever.
