Customers, like founders, have a gap between their stated beliefs and actual behaviors. Instead of relying on discovery interviews, watch them work. Observing their actions reveals their true operating philosophy—what they genuinely value—which is a more reliable guide for product development than what they say.

Tock rejected traditional focus groups and instead embedded its software engineers directly into restaurants to work shifts as hosts. This forced immersion gave the engineering team firsthand experience with the end-user's pain points, leading to a far more intuitive and effective product than surveys could produce.

The apocryphal Henry Ford quote is often used to dismiss customer research. Yet highly innovative companies like Apple invest millions studying customers to find deep-seated problems, not to ask for solutions. The real lesson is to research customer pains to inform visionary products.

Unlike sales-led companies that get feedback from sales calls, PLG companies are blind to their competitive positioning without formal research. You must conduct jobs-to-be-done interviews to uncover why customers chose you over alternatives, as relying on internal assumptions or simple "what do you love" surveys is misleading.

Instead of comparing to competitors, compare your product to the ideal human interaction. Google Meet aimed to be like a real conversation, not just better than Zoom. This 'humanization' framework pushes teams to think beyond features and focus on a more intuitive, emotionally resonant experience.

Stitch Fix's first-party data strategy succeeds because it creates a direct value exchange. When a customer provides feedback (e.g., pants are too long), they see a tangible improvement in their next delivery. This immediate reward system builds trust and turns data collection into a positive feedback loop for the customer.

Don't jump straight to building an MVP. The founders of unicorn Ada spent a full year working as customer support agents for other companies. This deep, immersive research allowed them to gain unique insights that competitors, who only had a surface-level idea, could never discover.

To truly understand a B2B customer's pain, interviews are not enough. The best founders immerse themselves completely by 'going native'—taking a temporary job at a target company to experience their problems firsthand. This uncovers authentic needs that surface-level research misses.

The acquisition of Clapp wasn't driven by market analysis but by the Lemlist team becoming passionate users first. The CEO fell in love with the product, leading to company-wide adoption. This bottom-up conviction in the product's quality was the starting point for the M&A conversation.
