The short answer: Problem-solution fit and product-market fit are milestones: they tell you where you are. The Traction Canvas gives founders the steps to reach each one, in order, with selling built in from the start.
| PSF and PMF | Traction Canvas | |
|---|---|---|
| Best for | Clear checkpoints to measure progress from problem to product-market fit. | Founder-led B2B sales, from first customer to $1M in ARR. |
| Not designed for | Showing how to sell between those checkpoints. | Revenue models, cost planning, or life after $1M. |

Box by box
How much PSF and PMF covers each Traction Canvas box. Full circle: a core focus. Empty: not covered. This is our own assessment; see all models compared.
What PSF and PMF does well
In Running Lean, Ash Maurya describes three stages: problem-solution fit (you have a problem worth solving), product-market fit (you have built something people want), and scale. Each stage has its own experiments and a clear signal that it is time to move on.
- It gives founders clear checkpoints instead of a vague idea of progress.
- It puts problem interviews before building.
- Its experiments make learning measurable.
How PSF and PMF maps to the Traction Canvas
The Traction Canvas has ten boxes in three zones, completed in order: Learn (Boxes 1 to 5), Earn (Boxes 6 to 9) and Scale (Box 10). Here is how PSF and PMF lines up with it.
Where PSF and PMF lands on the Traction Canvas. Faded boxes are not covered. The table below has the details.
| PSF and PMF | Traction Canvas | How it connects |
|---|---|---|
| Problem fit | Box 1: Problems Learn zone | Problems finds a problem big enough that people want to buy now, not later. |
| Problem-solution fit | Box 2: Bifurcation Box 3: Competition Box 4: Seven Second Sale Box 5: Enrolling Learn zone | Bifurcation, Competition, the Seven Second Sale and Enrolling test the solution with real buyers before you build. |
| Product-market fit | Box 6: Trigger Events Box 7: Disqualifying Box 8: Emotional Favourite Box 9: Won Sales Analysis Earn zone | Repeatable, qualified wins are the evidence of product-market fit. |
| Scale | Box 10: Marketing Moat Scale zone | The Marketing Moat grows the business through word of mouth. |
The gap PSF and PMF leaves
How far each canvas takes a founder on the road to $1M in ARR and a Series A. Bar strength shows how much of each zone is covered, using the box-by-box ratings above.
The fit milestones tell you when you have arrived but not how to sell in between. Getting meetings with strangers, qualifying opportunities and closing repeatably are the Earn boxes (6 to 9), which is where many founders with a good product stall.
When to use the fit milestones, and when to use the Traction Canvas
Use the problem-solution fit and product-market fit milestones when you need clear checkpoints to measure progress and report to mentors or investors. Use the Traction Canvas when you need to know what to do between those checkpoints: who to call, when, and how to turn conversations into repeatable sales. Box 5, Enrolling, gets you meetings with ideal customers before you build anything.
Frequently asked questions
Does the Traction Canvas replace the Lean Canvas fit stages?
No. It works alongside them. The fit stages are checkpoints, and the canvas is the sales playbook for reaching them.
Which Traction Canvas boxes show product-market fit?
The Earn boxes, 6 to 9. When your wins are repeatable and you can explain why you won them, you have strong evidence of fit.
