ProtoVibing: Build With Full Conviction, Test With Zero Attachment
Today I can babble words into a microphone and have five working prototypes created in a matter of seconds. But maybe zero of those are the right thing to do. The hardest part of building isn't building anymore. It's knowing what's worth building at all.
There was a time when the hardest part of building something new was actually making the thing. You needed the right brains in the room, weeks of work, and real resources just to get a prototype out the door.
That's not the constraint anymore.
Today you can generate five versions of something in 30 seconds. But maybe zero of those are the right thing to build. That shift changes everything about how we should be working.
Prototype As If You're Exactly Right. Test As If You're Completely Wrong.
I run a five-day challenge with founders and builders, and I don't let them build until day three. The first phase is deeply understanding your audience and your market. When building is this easy, you can build the wrong thing so fast, and keep building on top of it without ever stopping to ask if it should exist at all.
The methodology I've been developing, I'm calling ProtoVibing. Here's the core principle: when you have an idea, bring everything in your heart and gut to the prototype. Include your taste. Include all the connections you think it might be a part of. Make it well. Build it with full conviction.
But then test it as if you're completely wrong.
This resolves a psychological trap most builders fall into. Founders either over-believe in their idea and can't hear feedback, or they hedge so much the prototype is too watered-down to learn anything from. You need full conviction in the artifact so the feedback is meaningful, but zero attachment to the outcome. And crucially: don't pitch. The whole point is to understand the reaction, not to sell the thing.
ProtoVibing is a rapid succession of many prototypes, each one tighter and more informed than the last.
What a Win Actually Looks Like
A founder recently went through the five-day challenge. She had an idea for a platform to help people buy and sell used furniture. Within a week or two, she'd done real user research and discovered something important: people didn't want a platform at all. They wanted a physical location that buys furniture directly from homes, somewhere to visit in person, like an IKEA display. No app required.
She shelved the idea. That's a win.
Most founders spend months building the wrong thing before figuring out it won't work. She ran the process, got real signal from real humans, and made a clear-eyed decision before wasting serious time or money. The loop closed not with a product launch, but with a decision she could be confident in.
The Loop Doesn't Close Until It's in Someone Else's Hands
You cannot complete a loop by yourself. The loop doesn't close until your prototype is in the hands of another human being. Not in your head, not on your screen, not in a demo you rehearsed. In someone else's hands, getting their honest reaction.
Smaller teams can build faster than ever. That doesn't mean you should build alone longer. It means you can get something real in front of a potential user sooner. That's the actual superpower of this moment: faster validation, not just faster building.
Right now, most prompting and AI workflow happens solo. You, alone, on a computer. Builders today need something like paired programming: working alongside another human while you build with AI, bringing different perspectives and catching blind spots that solo iteration won't reveal. This is why I started the Pre-Beta Club, a free community design crit where builders share early work and get honest feedback from peers before it's too polished to change.
The core constraint isn't compute or speed or tooling. The constraint is other humans.
If you want to run this process with structure and accountability, I'm teaching this process live on Maven. Product-Market Fit Without Guessing is a four-week cohort where you run the full ProtoVibing loop: sharpen a real bet, build a clickable prototype with AI agents, put it in front of real customers, and leave with a tested prototype and a Design Partnership Agreement ready to send. The next cohort starts July 29.
We can generate faster than ever. But speed without validation is just building the wrong thing more efficiently. Build with conviction. Test with humility. And don't call it done until someone else has had their hands on it.
