Bottom line: a Reddit thread in r/PromptEngineering just dropped seven prompts that turn your everyday annoyances into validated business concepts. Worth bookmarking.
Most founders go looking for a market. The smarter move is going looking for a scar. Something that already frustrated you, cost you time, or made you build a janky spreadsheet workaround. That’s where real product ideas live. The reason this works is simple: you already have the pain data. You lived it. You know how long it takes, how often it happens, and how much it costs you in actual money or just sheer annoyance. You don’t need user interviews to validate that the problem is real because you are the user. This set of prompts, built around Eric Ries / Lean Startup principles, is designed to surface exactly that.
The Seven Prompts
- 🔍 The 30-Day Friction Miner. You list 3-5 recent frustrations from the last month. The AI digs up root cause, target audience, and a software or service concept for each one. The key here is being honest about what actually annoyed you, not what sounds impressive. “I had to manually copy data between two tools every morning” is a better input than “the B2B SaaS workflow is broken.”
- The Workaround Converter. Got a manual hack or a Frankenstein spreadsheet you rely on? Something you built because nothing else did exactly what you needed? This prompt turns it into an MVP concept with a clear value proposition. If you spent more than two hours building a workaround, someone else probably needs the real solution.
- 📊 The Pain-to-Frequency Matrix Builder. Scores your problem candidates on pain intensity, frequency, and market accessibility. Outputs a ranked list with a single top recommendation. This one is useful when you have five ideas and can’t decide which one deserves your next three months.
- The Monopolized Market Disrupter. Finds a wedge strategy against bloated incumbents using counter-positioning. Useful when the obvious market is already dominated but poorly served. Think project management tools: the space is crowded, but plenty of niches inside it are served by tools that try to do everything and end up doing nothing well.
- The Internal Tools Auditor. Looks at tools your company built for internal use and evaluates whether any of them have commercial SaaS potential. This one is worth running if you’ve ever worked at a company with a strong engineering team. Internal tools often solve real operational problems that the off-the-shelf market hasn’t caught up to yet.
- The Day-in-the-Life Friction Map. Walks through your workday hour by hour to surface the invisible micro-frustrations you’ve stopped noticing because you’ve accepted them as just part of the job. These are often the best ones because you’ve already proven the problem is persistent enough to tolerate.
- 🎙️ The Customer Validation Scriptwriter. Builds a Mom Test interview script (Rob Fitzpatrick’s method) focused on past behavior and real stories, not hypothetical interest. The distinction matters: “would you pay for this?” is a terrible question. “Tell me about the last time you had to deal with this” is a good one. This prompt sets you up to have the second kind of conversation.
Use Cases
These aren’t just for aspiring founders. A product manager validating a new feature can use the Pain-to-Frequency Matrix to pressure-test whether a roadmap item is actually high-priority or just loud. A consultant packaging a service can use the Workaround Converter to articulate why their informal process is worth formalizing and charging for. A developer deciding what side project to actually ship can use the 30-Day Friction Miner to stop choosing between projects on vibes and start choosing on evidence. The prompts work because they start from lived experience, not from brainstorming cool technology and working backward from features nobody asked for.
The question running through all seven: “Am I inventing a problem to match something I want to build, or am I starting from a real scar in my own experience?” That distinction separates ideas people talk about from products people buy. Most failed products weren’t badly built. They were built for problems that weren’t painful enough, or frequent enough, or specific enough to a real group of people.
Prompt of the Day
Try the Day-in-the-Life Friction Map. Walk AI through your workday in hourly blocks. Be specific and boring. The 9am meeting that always runs over because nobody prepared an agenda. The report you export and manually reformat every Friday before sending it to the same three people. The approval process that takes three days for something that takes three minutes because the right person is never available and there’s no system for async sign-off. Don’t filter yourself toward things that sound like startup ideas. Just describe what actually happens. Ask the AI to identify which of those micro-frustrations appear most frequently and which ones could be solved with a simple, focused tool. Then ask it to estimate how many other people in your role or industry probably deal with the same thing. You will find something worth thinking about.
Worth Your Time?
Yes. These are practical, grounded prompts built on solid frameworks from people who have written the actual books on this: Ries on validated learning, Fitzpatrick on honest customer conversations. They won’t write your business plan, but they’ll help you stop staring at a blank page wondering what to build. The structured format also matters. When you just brainstorm freely, you end up with ideas that feel exciting in the moment but fall apart when someone asks you who exactly would pay for it and why now. These prompts push you toward specificity from the start. Start with your frustrations. Let the prompts do the extraction work.
