The stuck feeling
Put it out there
A few people sign up
Nothing moves
You put it out there. A few people sign up. Someone sends a kind reply. You check again the next day, then the next. Nothing moves.
Now you can’t tell if the idea is bad or if nobody has heard of it. Both explanations feel the same from the inside, which is why guessing doesn’t help.
Put the problem, person, and path on one page
Problem
The problem
Person
The specific person
Path
Where they find you
Write three plain sentences on one page: the problem, the specific person who has it, and where that person would actually come across you.
Keep each sentence concrete. If you don’t know where that person would find you, write that down instead of filling the gap with a guess.
Look for the thinnest box
Problem
What hurts?
Customer
Who has it?
Channel
Where they find you
Price
What they pay
Look at four things: the problem, the customer, the channel, and the price. The weakest one is usually the real reason you’re not getting traction.
Find the box you can’t answer clearly, or the one you’ve only guessed at. That’s the one to check first.
Self-check, not a diagnosis

Talk to people who have the problem
Check where they go
Check where they already go for help
Talk to people who have the problem. Ask what they do about it now and where they already go for help.
Check those places yourself. Use what people say and what you find there to fill in the thin box, not a rewrite of your own assumptions.
Pick one box to fix this week
Pick one thing to change
Give it a week
Look at the same page again
Don’t try to fix all four boxes at once. Pick one thing to change this week.
Give it a week, then look at the same page again. See whether that box has a clearer answer and stronger evidence than before.
Example: a Lean Canvas filled in for one product
Hypothetical example
A fictional weeknight meal planner is shown for illustration only.
Problem
Meal planning after work feels hard to organize.
Customer segments
A household planning meals after work.
Channels
Thin boxA product page and local noticeboard.

First check: ask people who have the problem where they already go for help.
Open the Lean CanvasFrequently asked questions
Is it the idea or the marketing?
Check the problem, customer, channel, and price. Find the one you have only guessed at, then talk to people who have the problem.
How do I know which box is weakest?
Look for the box you can’t answer clearly, or the one you’ve only guessed at. Talk to people who have the problem and check where they already go for help.
Should I rebuild the product first?
Don’t try to fix all four boxes at once. Pick one thing to change this week, then look at the same page again after a week.
