Relying on customer interviews creates a false sense of understanding. The context gap between an interviewer and a customer living their job is too massive to bridge with questions alone. This leads to building products based on flawed, incomplete information.

Marketers frequently fail by assuming their target audience thinks, feels, and behaves as they do. The fundamental principle for success is to constantly remember this fallacy and instead get out to meet and understand the actual customer.

Treat customer conversations like coded messages. Create a "translation guide" by categorizing every statement into three buckets: their core goal (demand), the tools they use (supply), and random noise (irrelevant). This structure reveals what they'll actually pay for.

Your team's internal names for features often confuse customers. Systematically harvest the exact words customers use to describe outcomes during sales or support calls and use that language to rename features. This self-identifying language, used by Apple (e.g., "AirDrop," "Retina Display"), makes products instantly understandable.

Customers request specific features (supply), but this masks the true demand—the underlying problem they're trying to solve. Focusing on the 'why' behind the request leads to simpler, more effective solutions, like building a digest email instead of a complex 'advanced settings' page.

When customers talk, trust their articulation of what they're trying to accomplish (demand) and why their current tools fail (supply problems). However, completely disregard their suggestions for what product or feature you should build (supply they want). That is your job to design, not theirs.

Customers frequently complain about their current tools (e.g., "We're struggling with Salesforce"). Founders mistakenly interpret this as a request for a direct alternative. This is a trap. The real demand is the underlying job they're trying to do, which the tool is failing to support.

While there are infinite logical ways to describe your product, only one will resonate. It must directly mirror the customer's "Pull." If they need "visibility into AI failures," your pitch must be "we give you visibility into AI failures." Any other framing is a distraction that will cause confusion.

Customers often suggest solutions (e.g., "add this feature") based on their limited understanding of what's possible. A founder's job is to look past the specific request and identify the core problem or desired outcome. Building exactly what the customer asks for verbatim is a mistake; solving their underlying goal is the key.
