Everything on Customer Discovery

Firsthand observation and embedding with customers is superior to interviews for discovering product-market fit. Direct exposure to the workflow reveals the specific 'stuck' moments that customers may not articulate in a structured interview.

Impact: Reduces the risk of building the wrong product by grounding product decisions in observed reality rather than stated preferences.

Intro calls should be informal, demo-free, and focused on extracting intelligence. Recording these calls inhibits vulnerability and reduces the quality of information shared by prospects.

Impact: Unrecorded, conversational intro calls yield higher-quality intelligence, allowing for a more tailored and effective demo narrative.

The high watermark for customer understanding is the ability to run the customer’s business. This involves knowing their daily crises and operational bottlenecks, not just their surface-level pain points.

Impact: Ensures that the product solves a critical, high-value problem rather than a minor inconvenience, leading to stronger retention and willingness to pay.
