“When did you first start looking for something like this?”
From Bob Moesta · Author of Demand-Side Sales 101
Why it works
Moesta's demand-side model maps every purchase to a timeline: a first thought, a phase of passive looking, a trigger that activates active searching, a decision point, and a first use. This question pins the customer to the start of that timeline, which is the hardest phase to recover without a prompt — people remember the decision clearly but rarely volunteer what set it in motion. Once a customer names when they started looking, you can walk them forward through each phase, surfacing the specific events, anxieties, and trade-offs that drove progress. That sequence is the causal story of demand — which no feature survey can reconstruct.
When to ask
After a customer has signed up, made a purchase, or churned — any moment where you want to understand not just what they chose but the sequence of events that got them there. Pair it with 'what happened next?' to walk the full timeline forward.
Good follow-ups
- What was happening at that point that made you think you needed something?
- What did you try first — before you found us?
- Was there a specific moment when you decided you had to solve this now?
Watch out for
Customers often give a date without any context, which is useless alone. The follow-up question is mandatory: 'What was going on at that point that made you start thinking about it?' Without it, you have a timestamp instead of a trigger — and the trigger is what you actually need.
Where to ask
- User interviewgreat
The timeline that follows — what triggered the first thought, what they tried first, when they committed — is only recoverable in a live conversation where you can press for specifics.
- In-product surveypoor
Asynchronous, there is no way to follow the timeline into useful detail; the answer 'six months ago' tells you nothing on its own.
Reworded for this context: “What first made you start thinking you needed something like this?”
- Long-form surveypoor
Requires three to five follow-up probes to be useful; a fixed survey cannot adapt to which phase of the timeline the customer is describing.
