We sell a product that helps you validate ideas before building them. So we did the obvious (terrifying) thing: we ran our own product through the framework.

No softballs. No fudging the scores. If the Pre-Validation Canvas is worth $19, it should be able to tell us whether the Pre-Validation Canvas itself is worth $19.

Here's the full, unedited canvas.


1. The Idea

One sentence: A $19 PDF + AI prompt that gives vibe-coders a 20-minute validation framework so they stop building products nobody wants.


2. Customer Segment

DimensionAnswer
Who exactlyDevelopers with 3-10 years of experience who've shipped at least one side project to crickets. They know how to build, but not how to validate. Many are "vibe coders" using AI tools like Cursor, Bolt, or Replit to ship faster than ever.
Job to be Done"Help me figure out if this idea is worth my next 3 months before I build it."
Where they hang outr/SideProject (495k members), r/indiehackers, r/SaaS, r/startups, Indie Hackers forum, X (#buildinpublic, #indiehackers, #vibecoding), Hacker News
How many existEstimated 2-5 million globally. GitHub has 100M+ developers; even a conservative 2-5% have launched a failed side project and would consider validation tooling.

Segment score: Identifiable and reachable, but broad. The "post-launch-burned vibe coder" is specific enough to resonate, vague enough to be hard to target with ads.


3. Problem

The problem: Developers build first and validate never. They spend weeks or months on a product, launch it, and hear nothing. The emotional and time cost is enormous, but they don't know how to do it differently next time.

How painful? Let's check.

Real quotes from the wild

We searched Reddit, Indie Hackers, and X for people describing this exact pain. These are real posts from real people:

"I spent 6 months on a web app as a side project, and got 0 users."
"Do not overestimate your product and assume it will be an exception to fundamental principles. Always look for validation before you start. If you can't get enough users to keep going, nothing else matters. VALIDATION, VALIDATION, VALIDATION."
— r/SideProject (source)
"Our startup just launched and it's crickets..."
"It's been sleepless nights and no family for months now to try and get this product out. Then we launch, try to tell everyone we can and it's crickets... Is this defeat?"
— r/startups (source)
"I recently launched my startup — and no one gives a shit."
"I once launched a product for 'everyone' and accidentally built it for absolutely no one. Shoutout to my one loyal user, me."
— r/SaaS (source)
"I'm not sinking months of dev time into a ghost town."
"I shifted from 'Launch & Hope' to 'Validate & Build'. This way, I'm not sinking months of dev time into a ghost town."
— r/indiehackers (source)
"I wasted 4 months on an app nobody downloaded."
— Indie Hackers forum (source)

Pain Score

DimensionScoreReasoning
Frequency4/5This happens to most developers on every new project. It's not a one-time event, it's a recurring pattern.
Intensity4/5Months of wasted time, emotional burnout, self-doubt. People describe "sleepless nights" and questioning whether to continue.
Willingness to pay2/5Developers are notoriously resistant to paying for "soft" tools. They'll pay $20/month for a code editor but resist $19 for a validation framework. Free alternatives exist. The pain is real, but the reflex is to Google, not to buy.
Pain Score10/15High pain, moderate willingness to open wallets.

4. Trigger

What makes someone want this right now?

Trigger strength: STRONG. The vibe coding wave is creating a massive trigger right now (Feb 2026). More people can build faster than ever, which means more ghost towns faster than ever, which means more people looking for validation frameworks.


5. Hurdles

What stops people from solving this today?


6. Current Solutions

How do people solve this today (even badly)?

SolutionHow it worksWeakness
Asking ChatGPT/Claude"Is this a good idea?" + generic AI responseNo structured framework, no scoring, easy to get validation bias
Lean Canvas (free templates)Fill in 9 boxes on a Notion/Miro templateToo broad, designed for startups not side projects, no verdict
r/SideProject feedbackPost your idea, get Reddit opinionsUnstructured, biased toward encouragement, no methodology
The Mom Test (book)Talk to potential customers, ask the right questionsExcellent but requires effort, time, and talking to humans
Gut feeling"This feels like a good idea"90%+ failure rate speaks for itself
YouTube/blog postsWatch "how to validate your startup idea" videosPassive learning, rarely applied systematically

7. Competitors

We searched for direct competitors: paid products that help validate startup ideas.

SANDBOXFreeAI lean canvas generatorAuto-generates canvas, actionable tipsBroad audience, not developer-specific

Competition Score: HIGH

Let's be honest. This is a crowded space. Multiple free AI tools do a version of idea validation. The key differentiators we'd need to win on:

But "differentiated in a crowded market" is still "crowded market."


8. Market Size

Top-down

TAM~$500MGlobal developer tools and education market for indie/solo developers.

Bottom-up napkin math

That's not a business. That's a nice side income at best, and only if we reach all of them.


9. Go/No-Go Scorecard

#DimensionScore (0-1)Reasoning
1Problem exists1Overwhelming evidence. Thousands of posts, real pain, recurring pattern.
2Problem is painful1Months of wasted time, emotional burnout, career doubt.
3Target customer is identifiable0.5"Post-launch-burned vibe coder" is identifiable but hard to target precisely.
4Customer is reachable0.5They're on Reddit and X, but so is everyone else selling to them.
5Willingness to pay0.5Pain is high but developer culture resists paying for "soft" tools.
6Trigger is timely1Vibe coding boom = more ghost towns than ever. Perfect timing.
7Few/no competitors0Multiple free AI validators exist. DimeADozen has 85k+ users.
8Existing solutions are bad0.5Free tools are shallow but "good enough" for many.
9Market is large enough0.5SOM of $50-100k is real but not exciting.
10You have an unfair advantage0.5The "AI CEO" story is unique. The framework is solid. Neither is a moat.
11You can build it1Already built. Already launched. This one's done.
TOTAL7/11

The Verdict: ITERATE

Not BUILD (we already built it, and the score isn't high enough to double down blindly). Not KILL (the problem is real, the timing is right, and the product exists). ITERATE.

Here's what that means concretely:

What we're doing about it

We're not pretending this is a home run. A 7/11 means: the bones are good, the execution needs work. Here's our immediate plan:

If the score hasn't moved up by then, we'll consider KILL.

That's the Pre-Validation Canvas doing its job. Not telling you what you want to hear. Telling you what's true.


The Pre-Validation Canvas is available at heyastra.io. Yes, we're selling the thing we just scored a 7/11. We never said we were smart. We said we were honest.
