Validation and Prototyping
Build the demo before you build the product.
The fastest way to waste six months is to build something nobody wants. The fastest way to avoid that is to fake it first.
What you'll learn
- How to validate an AI product idea in under a week
- The "Wizard of Oz" method for AI prototyping
- When to use no-code tools vs. writing code
- What signals tell you to proceed — or pivot
The Wizard of Oz Prototype
Before you integrate a single API, simulate the AI experience manually. Create a form where users submit inputs. You (a human) process them using ChatGPT or Claude behind the scenes. Deliver the output as if the product did it automatically.
This tests the only question that matters: does the output actually solve the user's problem? If people don't care about the result even when a human curates it, no amount of automation will save the idea.
The 48-Hour Validation Sprint
Hour 0-4: Write the magic trick sentence. Build a landing page describing the outcome. Include a waitlist signup or a "try the beta" button.
Hour 4-12: Share the landing page in 5 communities where your target users hang out. Reddit, Discord, LinkedIn, niche forums. Don't pitch — describe the problem and ask if others face it.
Hour 12-36: For anyone who signs up, manually deliver the AI result using existing tools. ChatGPT, Claude, a Python script — whatever gets the output into their hands.
Hour 36-48: Collect feedback. Did they use it? Did they come back? Did they share it? These behavioral signals are worth more than any survey response.
Validation Signals That Matter
Go signal: Users come back unprompted and ask "when is the full version ready?"
Go signal: Users share it with colleagues without being asked
Caution: Users say "this is cool" but don't actually use it again
Stop signal: Users try it once and ghost. No follow-up. No questions.
Prototyping Without Code
You don't need to code a prototype. Use Typeform for input collection. Use Make or Zapier to connect it to an AI API. Use Notion or Airtable to store results. Use email to deliver outputs. The entire flow can be built in an afternoon.
The goal isn't a beautiful product. The goal is to learn whether the output is valuable. Ugly prototypes that deliver real value always beat polished products that solve imaginary problems.
Proceed, Pivot, or Kill
Proceed when users demonstrate behavior, not just words. They return, they pay, they share, they ask for more. Behavior is truth.
Pivot when the problem is real but your solution misses the mark. Users engage but the output isn't quite right. Adjust the output format, the input method, or the scope.
Kill when the problem itself isn't painful enough. If users shrug at a hand-curated result, automation won't help. Move on. The graveyard of startups is full of solutions to problems nobody has.
Try It Yourself
Pick your strongest idea from Lesson 2 and run the 48-hour sprint:
1. Write the magic trick sentence
2. Build a one-page site (Carrd, Framer, or even a Google Form)
3. Manually deliver AI results to 5 real users
4. Track: Did they use it? Did they come back? Did they tell anyone?
