Positive feedback and expressions of interest are misleading. The ultimate validation for a product idea is a customer's willingness to commit real currency, whether through direct payment or a signed letter of intent. Without this commitment, you have a charity, not a business.

If a large customer drags out a pilot indefinitely, it's a sign that your solution isn't solving a visceral, high-priority pain. When the need is urgent, enterprises will "bulldoze" through internal bureaucracy to get the product into production quickly.

Companies don't sign six-figure contracts to solve one person's frustrations. To justify a large purchase, you must anchor the sale to tangible business outcomes. Frame discovery questions around the company's goals, not just an individual champion's personal pain points.

To gauge a deal's urgency and qualify it, ask where the problem sits on their priority list. This forces them to state its importance out loud. It's psychologically difficult for someone to deprioritize something after they have verbally committed that it is a top priority.

Internal debates and market studies are noise. The clearest signal to build a new product is when a potential customer explicitly states they will pay for a simplified solution to a complex problem. This removes ambiguity and confirms a genuine, urgent need.

Chasing ten $10k deals over one $100k deal is a mistake. Smaller deals attract clients who nickel-and-dime you, don't fully buy into the vision, and provide distracting feedback. A single large deal provides a committed partner who will help guide your product roadmap.

Counterintuitively, selling high-value solutions to wealthy individuals or large companies often involves less friction. Affluent buyers with significant pain points focus on the value of the solution and have the budget, simplifying the sales cycle.

Investors warn that when potential customers delay adoption because your product isn't a top priority, it's a major red flag. This feedback almost always means 'never' and signals a fundamental lack of product-market fit, suggesting you are solving a 'nice-to-have' problem, not a 'must-have' one.

Replace speculative feedback from discovery calls with a process that would be "weird if it didn't work." First, get strangers to pre-pay for a solution. Then, deliver it manually. This confirms real demand (payment) and validates the solution's value (retention) before writing code.
