Embed engineers directly with customers to hear feedback and ship solutions, often on the same day. This radical structure eliminates layers of communication (Product Managers, Customer Success) and scales the 'founder energy' of talking to users and immediately building what they need.

Cursor's initial failed attempt at a 3D CAD tool highlights the "blind man and the elephant" problem. Despite interviewing engineers, the founders lacked an intuitive, first-hand feel for the user's daily workflow. This failure underscores that deep, personal domain experience is critical for founder-market fit, and cannot be replaced by secondhand research.

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.

Customers describe an idealized version of their world in interviews. To understand their true problems and workflows, you must be physically present. This uncovers the crucial gap between their perception and day-to-day reality.

While interviews yielded feature ideas, observing inspectors in the field ("ride-alongs") revealed the true bottleneck: hours spent writing reports at home. This insight allowed Spectora to ignore superficial requests and focus on the core workflow efficiency problem, which became their key marketing pillar.

To truly understand customers, go to their natural environment—their home or shop. Observing their context reveals far more than sterile office interviews. This practice, internally branded "Listen or Die," ensures the entire team stays connected to the user's reality.

Design thinking's immersion phase goes beyond understanding customer needs. By having innovators physically mirror the customer's experience, it forces them to confront and dismantle their own unexamined biases, leading to a fundamental reframing of the problem itself.

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.

To find product-market fit, Augment's team shadowed logistics operators for 60 days. This revealed a deeper problem than leaders described: massive email noise from listservs used as a workaround for 24/7 coverage. Building for the operator's messy reality, not the CEO's summary, is crucial for adoption.
