Why we picked it
Most founders treat customer research as a one-time pre-launch exercise, then go quiet once the product ships. Torres makes the opposite case: the core habit is talking to a handful of customers every single week, run by the same people building the product, so learning never stops. This is the clearest, most practical playbook for turning discovery into a standing rhythm instead of a project.

- The keystone habit is weekly touchpoints with 5 to 7 customers, done by the team building the product, not outsourced to a research department
- Use story based interviews (ask about a specific recent experience) instead of asking people what they want or would do in the abstract
- Tie every interview back to a desired outcome using opportunity mapping, so research drives decisions rather than piling up as notes

The people who cancel are telling you exactly what is broken, and most founders never ask. This Lean B2B guide shows how to catch that signal at the moment of cancellation with a short, low friction survey, then go deeper with a switch interview to hear the real reason someone left. It comes with a usable template, so it is a starting point you can ship this week rather than just theory.
From
Lean B2B
by Etienne Garbugli
~15 min read
- Trigger the survey inside the cancellation flow itself, when the reason is fresh, and lead with one blunt question: the single biggest reason for canceling
- Segment the answers by plan, persona, and tenure, since a churn reason from a trial user rarely means the same thing as one from a two year customer
- A short survey tells you what happened, but a jobs to be done switch interview tells you why they moved, which is the part you can actually act on

Young pushes past surface level feedback into a customer's actual reasoning and guiding principles, which matters once you are past launch and the easy problems are already fixed. It is a heavier read than a quick interview script, so pick it up once you want to understand why users behave the way they do, not just what they say they want. Best for a founder who has already run a few dozen calls and wants to go deeper.

Traynor's rule that you should never ask for feedback you are not prepared to act on is exactly the discipline the short answer is pointing at: pick one product decision a week that a real conversation informed, don't just collect opinions. He also warns against pulling feedback from everyone at once, which is a trap founders fall into once they have more users than they can personally track. Short, blunt, and worth rereading whenever your feedback inbox gets noisy.

This is the companion piece that explains why the context around a piece of feedback (who said it, when, and in what mood) changes how much weight it deserves. It is a useful corrective for founders who treat every support ticket or DM as equally important, which becomes a real problem once feedback starts arriving continuously instead of from a handful of early testers. Read it alongside the churn and support flow you are already reading.

Turns the vague feeling of product-market fit into a number you can move. Ask users how they would feel if they could no longer use the product, then track the share who say 'very disappointed'. Under 40 percent means keep working. A test you can run on an idea long before you scale it.

Doshi tells a visual, concrete story about a team that built for a problem customers said they had, but that was never actually near the top of the customer's own priority list, which is the trap you fall into if you collect feedback without weighing it. It is a fast read that sharpens exactly the judgment call the short answer asks for: which one product decision a week is worth making from what you heard.
