Understand your customers

How do I actually uncover the job my customers are hiring my product for?

The short answer

Interview people who recently switched to or bought something in your space and reconstruct the timeline: what triggered the search, what they used before, what pushed and pulled them. The story of the switch reveals the real job, not a survey asking 'what features do you want?'.
