Get Out of the Building

The question

Take the single biggest assumption your plan rests on — who the buyer really is, what they'd pay, why they'd leave what they use now — and ask yourself honestly where the evidence for it came from: a conversation this month with someone who owes you nothing, or a room full of people who already agree with you?

The idea

Steve Blank ran eight Silicon Valley startups across twenty-one years before he wrote any of this down. The Four Steps to the Epiphany, self-published in 2005, made an argument that sounds obvious now and didn't then: startups mostly fail with the product finished, because the standard plan is a product-development schedule with a launch at the end and no step anywhere in it where somebody checks whether the buyer exists. His answer was Customer Development — a second process running alongside engineering, opening with Customer Discovery, in which every part of the business model is written down as a hypothesis rather than a plan: who the buyer is, what problem they hold, what they'd pay, where they'd go looking. Then you take it outside, to people who have never heard of you. One line of his carried the whole method: there are no facts inside your building. Blank went on to teach it at Stanford, Berkeley and Columbia, and in 2011 built it into the Lean LaunchPad course the National Science Foundation adopted as I-Corps. The trap is going outdoors to be agreed with — collecting encouragement, coming back with the page untouched, and filing that as evidence.

The framework

01
Write the model down as guesses — with a number attached.
Before you go anywhere, put the business model on one page as sentences that could be contradicted: this person, holding this problem, which costs them roughly this much a month, currently handled this way, would pay this and would go here to look. The numbers matter because they're the part a stranger can argue with. If a line is written so loosely that no answer could disprove it — businesses want to save time — it isn't a hypothesis, it's a mood, and you'll come back from a week outdoors with it perfectly intact.
02
Who's allowed to go outside?
You are, and that isn't a motivational point. The value of the trip is a founder hearing the sentence that contradicts them, in the room, with the pause and the face that came attached — none of which survives a summary. Hand discovery to an agency or a junior researcher and you'll receive a competent report about people you have never met, which changes nobody's mind, because minds are changed by discomfort rather than by slides. Go yourself, take one other person, and let them write while you listen.
03
Ten conversations, booked before you feel ready.
Discovery works on volume long before it works on craft. One conversation gives you an anecdote; ten give you the thing three people said unprompted, which is the only kind of signal worth rebuilding a plan around. So book them first and prepare second — the calendar entry is the intervention, because there's no version of this where you feel adequately prepared, and waiting for that feeling is the most common way the whole exercise quietly doesn't happen at all.
04
A week outdoors that changed nothing was a sales tour.
The discipline lives in the debrief rather than the meeting. Come back to the hypothesis page and mark every line confirmed, changed or dead, with the sentence you heard that did it and the date, in writing, somewhere you'll read it again in a month. Blank's sequence puts discovery before validation for a reason: you don't get to move on to proving people will buy until the problem itself has survived contact. If nothing on the page moved, you weren't asking questions. You were presenting.
