Starting a business generates an overwhelming number of questions — about the idea, the market, the customers, the pricing, the name, the launch and the money. Most first-time founders spend months circling them without real progress. These ChatGPT prompts for starting a business help you work through them faster and more rigorously. Use them in sequence from idea to launch, or jump to the stage where you are stuck.
The 25 prompts are organised into five stages: validating your idea, understanding your market and customers, building your foundations, launching, and planning, funding and early growth. Once you are trading, there is a companion set of business prompts for strategy, operations and leadership.
How to Use ChatGPT Prompts for Starting a Business
Give the model real context — your idea, your customer and the problem you solve — and keep four rules in mind:
Be specific: the more detail about your idea and customer, the more actionable the output
Push back: follow up with ‘challenge these assumptions’ or ‘give me three ways this fails’
Verify facts: treat market sizes, competitor claims and any arithmetic as hypotheses to check
Get professional advice: company structure, tax, trademarks and fundraising need a qualified adviser before you commit
You can run these in a free AI chat across several AI models and compare — where two models disagree about your idea is usually the part worth examining.
The most expensive mistake in starting a business is building something nobody wants. These five prompts stress-test your idea before you spend serious time or money. Claude Sonnet 5 makes a thoughtful sceptic for this stage.
1. The brutal idea stress test
I am considering starting a business with this idea: [describe it in two or three sentences — what you sell, who buys it, why they would pay for it].
Be a sceptical but constructive investor. Identify the three biggest assumptions I am making that would kill this business if wrong. For each, suggest the cheapest and fastest way to test it before spending serious money. Identify competitors or substitutes I may be underestimating. Tell me what would need to be true about the market, the customer and my execution for this to succeed. Then give me an honest assessment: genuinely differentiated, crowded market entry, or something in between? Flag which parts of your answer are inference rather than something I told you.
2. The problem-first validation
I believe this problem exists for this group of people: [describe the problem and who has it in specific terms — not “small business owners” but “freelance graphic designers who manage their own invoicing and spend three to four hours a week on admin”].
Help me validate whether this is real, painful and underserved: what do people in this situation currently do about it — what are their workarounds? Rate the severity from minor inconvenience to urgent crisis, with reasoning. What signals would tell me this is painful enough that people will pay? Suggest five questions I could ask in a discovery interview that would reveal whether it is real for them. And what would a version of this problem look like that is too small to build a business around?
3. The minimum viable business model
My business idea is: [describe it]. I want to validate whether this can be a real business before building anything significant.
Design the smallest version I could run in the next 30 days to test whether people will pay: what exactly I would offer; how I would find the first five potential customers without spending on marketing; what I would say to get them to pay or commit; what price point I would test and why; what a successful outcome after 30 days looks like; and what a failed outcome looks like and what I should do if I get there.
4. The competitor landscape
I am entering this market with this idea: [describe both]. The direct competitors I know about are: [list them, or say you are not sure]. I believe my differentiation is: [describe it, or say you are still working it out].
Help me map the landscape: which direct competitors should I be aware of, and which indirect competitors or substitutes might my customer use instead? For each category, what are their likely strengths and weaknesses? Where are the genuine gaps an entrant could exploit? What positioning would give a new entrant the best chance against incumbents? Treat any specific company you name as a starting point for me to verify rather than established fact, since your information may be out of date.
5. The go / no-go decision
Here is what I have learned from testing my idea so far: [summarise interviews, sign-ups, pre-orders and feedback]. My original success criteria were: [describe]. Act as a neutral adviser. Based only on this evidence, should I continue, pivot or stop? Explain which evidence is strong and which is weak, what I might be reading into it because I want it to work, and the single next test that would settle the question.
If prompt 5 says stop or pivot, that is a result, not a failure. Our ChatGPT prompts for problem solving can help you reframe the idea before you test again.
Most founders build for a vague idea of a customer rather than a specific one. These five prompts help you get precise about who you serve and how to reach them. Gemini 3 Pro can work through long interview notes in one go.
6. The ideal customer profile
My product or service is: [describe it]. I believe my target customer is: [describe them as specifically as you can].
Build me a precise ideal customer profile for the person most likely to buy quickly, pay a fair price and refer others: a specific description with job, life situation, goals and values — not “millennials”; their top three frustrations with how this is currently solved; what they are actively searching for; where they spend time online; what would make them trust a new solution; the objections they would raise and the most convincing responses; and how they would describe this problem in their own words, so I can use their language rather than mine.
7. The customer discovery interview script
I am about to start customer discovery interviews for: [describe your idea]. My target customer is: [describe them]. The problem I am trying to validate is: [describe it].
Write me a complete interview guide: an opening script explaining why I am talking to them without pitching my solution; five to seven core questions designed to uncover whether the problem is real, painful and actively being solved; follow-up probes for when they give a surface answer; questions revealing what they currently do and what they spend on it; a closing section on how they would ideally want it solved; what to listen for that would confirm or challenge my assumptions; and what I should not say, to avoid biasing them toward what I want to hear.
8. The market sizing exercise
My business idea is: [describe it]. My target customer is: [describe them]. I am initially targeting: [describe the geographic or demographic scope].
Help me build a bottom-up market sizing estimate: walk me through the calculation — how many potential customers exist, what percentage might realistically be addressable in year one, and what revenue that represents at my likely price point. Show every step so I can check the arithmetic. State each assumption explicitly and tell me how sensitive the total is to each. What market size would justify a sustainable business versus a venture-scale one? And treat any population or market figure you use as an estimate I need to verify from a real source before relying on it.
9. The positioning statement
My product or service is: [describe it]. My target customer is: [describe them]. My primary competitors or alternatives are: [list them]. What makes me different is: [describe it, or say you are still working it out].
Help me develop positioning: write three different statements using the format “For [target customer] who [problem], [name] is the [category] that [key benefit], unlike [alternative] which [limitation].” For each, explain who it resonates with most and what it sacrifices. Which would be hardest for a competitor to copy, and why? Write the one-line version for a homepage headline. And what does this positioning imply about the customers I am choosing not to serve?
10. The interview synthesis
Here are my notes from [number] customer discovery interviews: [paste, with names removed]. Summarise the recurring problems, how people solve them today, what they spend, the exact phrases they use and any surprises. Separate what people actually did from what they said they would do, and tell me which of my assumptions the interviews support and which they challenge.
Run prompt 10 after every batch of five interviews. The AI summarizer is a quick way to condense raw notes before you paste them in.
Once your idea and customer are clear, these prompts build the foundations: pricing, name, business model, finances and admin. The AI business plan generator turns the output into a structured plan, and DeepSeek V4 Pro is useful for checking financial reasoning step by step.
11. The pricing strategy
My product or service is: [describe it]. My target customer is: [describe them and their budget sensitivity]. My competitors charge approximately: [describe if known]. My costs to deliver are approximately: [describe, or say unknown].
Help me develop pricing: recommend a model — one-time, subscription, usage-based, tiered, freemium — and explain why it fits this product and customer. Suggest a specific price point or range with reasoning. How should I think about anchoring? What is the risk of pricing too low, and too high, for this specific customer? And how should pricing evolve — what changes at 100 customers versus 1,000?
12. The business name generator
I need to name my business. Here is what it does: [describe it in two or three sentences]. My target customer is: [describe them]. The tone I want is: [professional and trustworthy, friendly and approachable, bold, calm and premium]. Names I like and why: [list, or say none yet]. Directions I want to avoid: [describe].
Generate five descriptive names that say what the business does, five evocative names that create an association without describing the product, and five invented or abstract names. Give each a one-line rationale and flag pronunciation risks. Tell me which three are strongest and why. Do not tell me whether a name is available or trademark-free — you cannot know that. Instead, list exactly which registers and databases I should search myself before committing.
13. The business model canvas
My business idea is: [describe it]. My target customer is: [describe them]. I am planning to charge: [describe your pricing model].
Build me a complete business model canvas: customer segments, including any secondary ones; the value proposition and the problem it solves; the channels for reaching and delivering; the customer relationship each segment expects; revenue streams, including any I am not considering; the key resources this business absolutely requires; the critical activities; the partnerships that bring what I cannot efficiently build; the cost structure split into fixed and variable; and finally, where the biggest risks and dependencies sit in this model.
14. The financial model starter
I am building a [type of business: SaaS, service business, e-commerce store, marketplace]. My pricing model is: [describe it]. My expected monthly costs are approximately: [estimate, or say unknown]. I am bootstrapping with approximately: [amount, or say limited budget].
Help me build a basic financial model: which metrics should I track from day one for this type of business? Build a simple 12-month revenue projection on realistic acquisition assumptions, stating every assumption clearly and showing the calculation so I can check it. What is my break-even point? What does cash flow look like in the first six months if things go to plan, and if growth is half as fast? And which two or three financial decisions now will most affect whether this survives year one? Treat this as a structure for me to fill with real numbers, not a forecast — and take proper accounting advice on tax and structure.
15. The legal and admin checklist
I am starting a [type of business] in [country or region] as a [sole trader / partnership / limited company, or say unsure]. Give me a checklist of the legal, tax and admin topics to sort out before and shortly after launch — registration, tax, insurance, contracts, data protection and licences — and for each, the question I should ask an accountant, solicitor or official adviser. Do not tell me what the rules are; they vary by jurisdiction and change often.
Getting your first customers is the hardest part of starting any business. These five prompts plan a focused, realistic launch. For the marketing execution that follows, there is a wider set of ChatGPT prompts for marketing.
16. The go-to-market plan
I am launching [describe your product] for [describe your target customer]. My budget is approximately [state it, or say close to zero]. I want my first [number] paying customers within [timeframe].
Build me a focused go-to-market plan: which two or three channels are most likely to reach my customer cost-effectively at this stage? For each, describe the specific tactics for the first 90 days — not general strategies. What should launch week look like, day by day? How should I sequence my marketing? What are the biggest mistakes founders make at this stage? And what does early traction look like for this type of business?
17. The first customer acquisition plan
My product or service is: [describe it]. My target customer is: [describe them specifically]. I have not launched and have no existing audience.
Help me get my first five paying customers: where do my customers gather online and offline right now — list specific communities, platforms, events and publications. Write a direct outreach message under 100 words, no jargon, no hard sell. Write a post I could make in a community where my customers spend time that generates genuine interest without being spammy — and check it against the norms of that kind of community, since posting promotionally where it is unwelcome does more harm than good. What is the fastest path from zero to a first paid customer? And what could I offer the first five that I could not sustain at scale?
18. The homepage messaging framework
My product or service is: [describe it]. My target customer is: [describe them]. The problem I solve is: [describe it]. My key differentiator is: [describe it].
Write the core messaging for my homepage: a hero headline under ten words that immediately says what I do and for whom; a supporting subheadline explaining the specific value and outcome; three benefit statements rather than feature descriptions; a primary and secondary call to action with exact wording; what the above-the-fold section should contain and in what order; and two or three things I should absolutely not say. Do not write testimonials or invent social proof — if a section needs it, mark it as a placeholder for something real.
19. The content and SEO strategy
I am launching [describe your business]. My target customer is: [describe them]. I have a limited budget and cannot spend on paid advertising initially.
Build me an organic content and SEO strategy for six months: what are the five to ten most important search queries my customer makes when looking for a solution — identify the keyword, the search intent, and the content format that would rank best for each. Treat these as candidates for me to validate in a keyword tool rather than volume estimates. What should I create first, prioritised by search volume, competition and relevance? What non-paid channels beyond SEO could reach my audience? How much content, at what frequency, to see meaningful results? And what single piece would do the most work?
20. The founder story
I am starting [describe your business]. My background is: [describe your relevant experience, skills, and any personal connection to the problem]. I plan to build a public presence on [platform].
Help me develop my founder story: what is the most compelling version of why I am starting this? Write it as a two to three paragraph origin story for my About page. Give me the one-line version for a bio. What content themes should I post consistently to build credibility with my target customer? What is the single most credibility-building thing I could publish in the first 30 days? And how do I balance a founder brand against the company brand — when does the balance shift? Use only what I have told you about my background; do not embellish it.
Five prompts for keeping momentum after launch: a roadmap, a risk register, funding choices, a pitch and a weekly review. GPT-5.6 Sol is good at structured, phased plans.
21. The 90-day roadmap
I am launching [describe your business]. My current situation: [what you have built, what stage you are at, what resources you have]. My goal for the next 90 days is: [first revenue, first customer, MVP launch].
Build me a focused 90-day roadmap: break it into three monthly phases with a clear goal for each. For each phase, list the five to eight highest-priority tasks. Identify the two or three things that would derail the whole plan if delayed or skipped. What should I actively not do in the first 90 days, even if it feels important? And how will I know at the end whether I am on track — what are the three key indicators?
22. The risk register
I am planning to start [describe your business]. My target customer is: [describe them]. My business model is: [describe it]. My go-to-market strategy is: [describe it].
Build a risk register: identify the ten most significant risks across market, execution, financial, competitive, and regulatory or legal categories. Rate each for likelihood and impact. For the five highest-priority risks, suggest a specific mitigation. What single risk could end this business in year one if not managed? What early warning signals should I watch in the first six months? On anything regulatory or legal, tell me what to ask a professional rather than answering it yourself — requirements vary by jurisdiction and change often.
23. The funding options comparison
I am starting [describe business] and need about [amount] over [timeframe]. Compare the main funding routes — bootstrapping from revenue, personal savings, loans, grants, crowdfunding, angel investment and accelerators — on control, risk, speed and what each expects in return. Tell me which seem to fit my situation, and list the questions I should put to a financial adviser before choosing.
24. The investor or advisor pitch
I am building [describe your business]. I need to raise [amount] from [angel investors, a seed fund, an accelerator, a strategic partner], or recruit [describe the advisor or co-founder].
Help me prepare: write a two-minute verbal pitch covering the problem, the solution, the market, the business model, the traction so far, and what I am looking for — using only traction I have actually described, with placeholders where I have none. Identify the five questions this person is most likely to ask and write a strong answer to each. What is the hardest question, and the most honest and compelling way to answer it? What do I need ready before the meeting, and what can I not afford to be vague about?
25. The weekly founder review
Guide me through a 15-minute weekly founder review: what moved the business forward this week, what did not, what customers told me, which number I am watching and the one priority for next week. Ask one question at a time, then give me a short summary I can compare week to week.
Prompt 25 is the one to keep running every week. For turning your roadmap into timelines and status updates, see our ChatGPT prompts for project management.
These prompts are tools, not answers. No model can tell you whether your idea will succeed, but it can help you think more rigorously and spot blind spots earlier. Save the prompts that work best as one-click templates in Chat Smith, and start with prompt 1 on the idea you are most attached to — that is the one least likely to have been tested honestly.
For prompting technique in general, see the main ChatGPT prompts guide, and once the business is running, our ChatGPT prompts for work help with the day-to-day.
ChatGPT prompts for starting a business are written requests that ask ChatGPT to brainstorm a business idea, draft a rough plan, or outline first steps like registering a company. They work best with specific details about your industry, budget, and location. Chat Smith gives you access to ChatGPT and other models in one place.
