You can build almost anything now. That is exactly why most of it dies.
Cruxible is a pre-validation market scout for solo devs, indie hackers, and vibe coders. Before you write a line of code, we go do the brutal pre-validation research most builders skip. Real pain, real demand, real buyer intent. So the months you are about to pour into this do not disappear into silence.
We cannot promise your startup will succeed. No one honestly can. We can make sure the time, money, and effort you bet are pointed at something the market actually wants.
Why we built this
We are not here to sell you a dream. We have watched too many of them die.
The hard part of building a company was never the typing. It was choosing the right thing to build, and being honest about whether anyone out there actually wanted it. That is the part almost no one does, because it is slow, lonely, and full of answers you might not want to hear.
So we built Cruxible to be the thing we wish had grabbed us by the collar before the build started. Not a cheerleader. A scout. Something that does the unglamorous market research grind first, and tells you the truth about whether the market is there, before you bet your nights and weekends on it.
If you are a solo dev, an indie hacker, a vibe coder, or someone who got pushed out by AI and decided to bet on yourself instead, this is for you. The playing field is brutal and the odds are not kind. We cannot change the odds for the whole market. We can make sure that when you do bet, you are betting on evidence instead of hope. That is the entire reason Cruxible exists.
The problem, in numbers
The reason most of these bets fail is not bad code. It is a market that was never there.
The graveyard is full of products that worked perfectly and that nobody wanted. Here is what the research actually says, with sources, so you can check it yourself.
43%
of startup failures involve poor product-market fit.
CB Insights, 2026 review of 431 venture-backed shutdowns. Running out of money was usually the downstream symptom, not the root cause.
74%
of high-growth startups fail from premature scaling.
Startup Genome. They built and scaled before verifying that real demand existed.
2x
the front-end effort. That is what separates winners.
PDMA Handbook, Cooper synthesis. Successful firms spend roughly twice as much time and money on the homework before the build. Cutting it drives success rates down.
80 / 75
80% of new-product successes used more market info than average. 75% of failures used less.
Ottum & Moore. More front-end market evidence correlates with a higher success rate. Not a guarantee. A correlation strong enough to take seriously.
The false start
is one of the most common ways first-time founders fail.
Thomas Eisenmann, Harvard Business School, Why Startups Fail. Skipping pre-build market discovery and jumping straight to the MVP.
Notice the pattern. Every one of these failures was decided before the first line of code, by what the builder did or did not learn about the market first.
In their own words. Real builders, not our customers.
“I built something nobody wanted, and shut it down.”
“I spent months building a product I was sure would succeed. Only to discover nobody actually wanted it.”
“I spent 3 months perfecting the algorithm. I spent 3 hours talking to users about pricing.”
“Some nights I stare at my screen wondering if my wife is right.”
The shift
AI made building easy. It made choosing harder than ever.
A few years ago, the bottleneck was clear. Can I even build this? Most people could not, so the ones who could had an edge just by shipping.
That edge is gone. With AI coding tools, anyone can ship a working app in a weekend. Which means the question that decides who survives is no longer “can I build it?” It is “should I build this one?”
That is the question almost nobody answers honestly, because answering it means doing market research, and market research is slow, tedious, and full of evidence you might not want to hear. So builders skip it. They build the thing that excites them, ship it, and meet the silence.
Cruxible is the half of vibe coding that got left behind. The tools handle the building. We handle the should.
Why Cruxible exists
We do the brutal research first, so you do not bury another year of your life.
The honest path through pre-build research has always existed. You could spend days digging through forums, reading competitor pages, hunting for what people actually pay for, and being ruthlessly honest about whether the pain is real. Almost nobody does, because it is grueling and your own excitement fights you the whole way.
The other path was to hire it out. A market research consultant or research firm runs from a few thousand dollars for a one-time engagement up to far more for ongoing work. Out of reach for someone building on nights and weekends.
Cruxible does that pre-build research at a fraction of that cost. You paste your idea. We go scout the market. We mine real pain in the places your buyers actually complain, look for real commercial intent and what people already pay for, map who else is in the space, and grade every piece of evidence so you can see how strong the signal really is. Then we hand you a clear read on whether this is worth your build, before you write a line of code.
Only facts, data, and real signals. We are the friend who asks “are you sure?” before you spend the weekend, not the one who tells you what you want to hear.
The honest part most tools will not put in writing
What we promise. What we will never promise.
- We will do the pre-build market research most builders skip, and show you the evidence with sources.
- We will grade that evidence honestly, including when it is weak.
- We will tell you what the market is actually saying, even when it is not what you hoped.
- If we do not surface real evidence for you to act on, we will make it right.
- We will never call your idea proven. Real proof needs real users paying for a real product. That comes after the build, and it is your job, not ours.
- We will never predict that your startup will succeed. No tool can do that honestly. Anyone who claims it is selling you a feeling.
- We will never replace talking to your actual customers. We scout the market before you build. The human conversations come after, and they are on you.
- We will never hand you certainty. We hand you evidence. You still make the call.
The research says more front-end homework correlates with a better shot at success. That is the most we will claim, and it is backed by sources. The decision, and the odds, stay yours.
Scout it before you build it.
If you are about to bet the next few months of your life on an idea, spend a few minutes finding out what the market already thinks. It is a head start most builders dismiss, right up until the silence after launch teaches them why they should not have.
Evidence first. No hype. You decide.
