TL;DR

Founders don't run out of problems — they run out of hours to think through all of them well. This post collects 80 ChatGPT prompts organized into eight areas founders wrestle with daily: validating ideas, raising money, launching products, growth marketing, social content, sales, hiring, and retention. Use them as starting points, not finished thinking — the value is in how you push back on ChatGPT's answers, not in copying them.

Why Prompts Matter More Than the Tool

Everyone talks about ChatGPT like it's a vending machine: put in a prompt, get out an answer. That framing undersells what's actually useful about it for founders. The real value shows up when you use it as a sparring partner — something that can generate ten mediocre options in the time it would take you to generate two good ones, so you can pick the interesting bits and throw the rest away.

A vague prompt gets a vague answer. "Give me marketing ideas" produces a list any founder could write themselves after two cups of coffee. A specific prompt — one that names your customer, your constraint, your stage — produces something you can actually argue with. That's the real skill here: not prompting, but knowing which questions you haven't asked yourself yet.

The 80 prompts below are organized by the stage or function most founders find themselves stuck on. Treat each one as a template — swap in your industry, your numbers, your customer, and see what comes back.

Startup and Product Idea Validation

Before you build anything, you need to know whether the problem is real and whether you're the right person to solve it. These prompts are built to poke holes in an idea rather than flatter it.

1. Act as a skeptical early customer. I'm building [describe idea]. What are the three biggest reasons you wouldn't pay for this?
2. What assumptions is this business idea resting on that I haven't stated out loud: [describe idea]?
3. Name five industries that still run on spreadsheets or phone calls that shouldn't.
4. If [describe idea] fails in 18 months, write the most plausible postmortem explaining why.
5. What would a much larger, well-funded competitor build if they entered this exact space tomorrow?
6. I have two ideas: [idea A] and [idea B]. Steelman the case for each one being the wrong bet.
7. What's a boring, unglamorous problem in [industry] that nobody wants to solve because it doesn't sound exciting on a pitch deck?
8. Describe the smallest possible version of [describe idea] I could build in two weeks to test demand.
9. What existing behavior would customers have to change to adopt this product, and how big of an ask is that really?
10. Who has tried to solve this exact problem before, and why do you think they didn't succeed?

Fundraising and Investor Conversations

Raising money is part storytelling, part negotiation, part knowing the numbers cold. These prompts help you prepare for the parts of fundraising that are easy to underrate until you're in the room.

1. Act as a venture investor reviewing my startup. Ask me the five hardest questions you'd ask before writing a check.
2. Here's my current traction: [describe metrics]. Which numbers would a seed investor actually care about, and which are vanity metrics?
3. Write a rejection email a VC might send after a first meeting, based on common concerns about a startup like mine in [industry].
4. What's the difference in what an investor wants to hear at pre-seed versus Series A, and how should my pitch change accordingly?
5. Help me explain my unit economics in one paragraph a non-technical investor would understand.
6. What are three ways founders unintentionally signal weakness in a pitch meeting without realizing it?
7. I'm raising a bridge round. What questions should I expect about why I need one?
8. Draft three answers to "What happens if a big company builds this feature for free?"
9. What terms in a term sheet most often surprise first-time founders, and what should I ask my lawyer to explain?
10. How should I think about giving up board seats versus giving up equity when negotiating with investors?

Product Launch Planning

A launch is really a sequence of smaller bets — what you say, when you say it, and who hears it first. These prompts help you plan the sequence instead of winging it.

1. Build a two-week countdown plan for launching [describe product], including what to post and when.
2. What's a launch mistake that looks harmless in the moment but quietly kills momentum?
3. Write three different taglines for [describe product] aimed at three different customer segments.
4. What questions should I expect from press or bloggers covering a launch like this, and how should I answer them?
5. How do I structure a beta waitlist so it builds anticipation instead of just collecting emails that go nowhere?
6. What's a creative, low-cost way to make my launch day feel like an event rather than a blog post?
7. Draft a launch-day social post that doesn't sound like every other "we're live!" announcement.
8. What should I ask my first 20 users within 48 hours of launch to get useful, actionable feedback?
9. How can I turn early user feedback into a public changelog that builds trust instead of looking chaotic?
10. What's a smart way to re-launch a product that had a quiet first release and didn't get traction?

Growth Marketing Strategy

Marketing for a startup is different from marketing for an established brand — you're usually short on budget and long on hustle. These prompts lean into that constraint.

1. What are three unconventional marketing channels for a company selling [describe product] to [describe customer]?
2. I have $500 to spend on marketing this month. What's the highest-leverage way to spend it?
3. What's a distribution channel that's currently underpriced or underused in [industry]?
4. Write a positioning statement for [describe product] that a competitor couldn't copy word-for-word and have it make sense for their product.
5. How can I use SEO to compete against companies with ten times my content budget?
6. What's a partnership I could pitch to a complementary (not competing) business in my space?
7. How do I figure out which of my current customers are most likely to refer others, and what should I ask them?
8. What's a way to repurpose one long piece of content into a week's worth of smaller posts without it feeling recycled?
9. How should my marketing message change depending on whether a visitor is hearing about us for the first time or the fifth time?
10. What's a common growth-hacking tactic that's actually overrated for a company at my stage, and why?

Social Media and Content

Social media rewards consistency more than cleverness, but consistency is hard when you're also running a company. These prompts are meant to lower the friction of showing up regularly.

1. Give me five hook lines for a LinkedIn post about [topic] that don't start with "I used to think..."
2. What's a content format on [platform] that's currently getting more reach than static posts, and how could I adapt it?
3. Write three versions of the same announcement — one for LinkedIn, one for Twitter/X, one for Instagram — each matching that platform's tone.
4. What questions do people in my audience Google that I could answer in a short video?
5. How can I turn a customer complaint into a piece of content that builds trust instead of looking defensive?
6. What's a way to show behind-the-scenes work at my startup without it feeling like a humblebrag?
7. Draft a week's worth of post ideas based on this single insight: [describe insight or lesson].
8. What's the difference between content that gets likes and content that gets replies, and how do I write more of the second kind?
9. How should my posting strategy differ if I'm trying to reach other founders versus trying to reach end customers?
10. What's a low-effort way to test which content topics actually resonate before investing in a full content calendar?

Sales and Lead Generation

Selling as a founder is different from selling as a hired rep — people are buying you as much as the product. These prompts focus on that dynamic.

1. Act as a prospect who's interested but hesitant. What objections would you raise about buying [describe product]?
2. Write a cold outreach message to [describe target customer] that doesn't sound like a template.
3. What's a better way to open a sales call than asking "How's it going?"
4. How should I qualify a lead in the first five minutes of a call without sounding like I'm interrogating them?
5. What's a follow-up sequence for a prospect who went quiet after a demo?
6. Help me turn this customer testimonial into three different pieces of sales collateral: [paste testimonial].
7. What questions reveal whether a prospect has budget authority without asking about budget directly?
8. How do I price a new feature I'm about to launch without undervaluing it or scaring off existing customers?
9. What's a way to use a free trial that actually converts, instead of just delaying the sales conversation?
10. Write a short case study outline based on this customer result: [describe result].

Hiring and Team Culture

Every early hire shapes the culture more than any values document ever will. These prompts are built to help you hire — and manage — with intention.

1. Write a job posting for [role] that reflects our actual culture instead of generic corporate language.
2. What interview questions reveal how a candidate handles ambiguity, which matters more at a startup than at a big company?
3. What are signs during an interview that someone is a strong operator but a poor culture fit for an early-stage team?
4. How should I structure a 30-60-90 day plan for a first hire in [role]?
5. What's a fair way to talk about equity with an early employee who's taking on real risk by joining us?
6. Draft three interview questions that test for self-direction without sounding like a trick question.
7. What's a warning sign that a candidate will struggle once the initial excitement of joining a startup wears off?
8. How do I give critical feedback to someone who's clearly working hard but not delivering the right results?
9. What should a founder do differently when hiring employee #3 versus employee #30?
10. How can I build a hiring process that moves fast without skipping the steps that actually predict success?

Customer Retention and Email

Keeping a customer is usually cheaper than winning a new one, but retention rarely gets the same attention as acquisition. These prompts push toward the unglamorous work of keeping people around.

1. Write a win-back email for a customer who canceled three months ago, without sounding desperate.
2. What are three reasons customers churn that never show up in an exit survey?
3. Draft an onboarding email sequence for a new customer of [describe product] that gets them to their first "aha" moment fast.
4. How can I segment my email list by usage behavior instead of just demographics?
5. What's a subject line style that outperforms "Quick question" without feeling gimmicky?
6. Write a monthly product update email that customers actually want to open.
7. What's a proactive way to reach out to a customer whose usage is dropping, before they decide to cancel?
8. How should a renewal reminder email differ from a first-time sales email in tone and structure?
9. What questions should I ask my most loyal customers to understand what's actually keeping them around?
10. Draft a survey with five questions that will tell me more about churn risk than a standard NPS score.

Making the Prompts Actually Work For You

None of these 80 prompts are magic on their own — the value comes from the follow-up. When ChatGPT gives you an answer, the useful move is rarely to accept it and move on. It's to ask "why not the opposite?" or "what would someone who disagrees with this say?" or "give me a version of this that's twice as specific." That second and third round of questioning is where the actual thinking happens.

It also helps to feed these prompts real context — your actual metrics, your actual customer quotes, your actual competitors — rather than keeping things abstract. A prompt like "write a cold email" gets you a template. A prompt like "write a cold email to a VP of Ops at a 200-person logistics company who just posted about supply chain delays" gets you something you could send today.

Save the prompts that work for your business, tweak the ones that almost worked, and don't be precious about the ones that flopped. The goal isn't to have the perfect prompt library — it's to lower the cost of asking yourself hard questions often enough that you actually do it.
