When your first users sign up but never return, it's a clear signal of a problem-solution mismatch. Before abandoning the idea, you must interview these users to understand why. Their feedback is crucial data needed to decide whether to iterate or pivot.

The goal of early validation is not to confirm your genius, but to risk being proven wrong before committing resources. Negative feedback is a valuable outcome that prevents building the wrong product. It often reveals that the real opportunity is "a degree to the left" of the original idea.
Juicebox's initial product went viral, gaining 100 paid users overnight. However, high churn revealed the product was weak. The team correctly interpreted this not as failure, but as "message-market fit"—proof they were solving a real pain point, which gave them the conviction to keep building.
The founder's previous experience at Snap, where he saw phenomenal user retention, gave him a clear benchmark for what "good" looks like. When his own music app's Day 30 retention was "catastrophic," he knew it wasn't a viable business and made the tough decision to pivot rather than settle for mediocrity.
A key viability metric for consumer subscription apps is achieving 30-40% Day 1 retention. Anything lower suggests a fundamental product-value mismatch, making it mathematically difficult to acquire enough users to build a sustainable active user base.
Don't treat validation as a one-off task before development. The most successful products maintain a constant feedback loop with users to adapt to changing needs, regulations, and tastes. The worst mistake is to stop listening after the initial launch, as businesses that fail to adapt ultimately fail.
The biggest initial hurdle for a new product isn't getting the first dollar of revenue; it's crossing the chasm from a user trying the product once to becoming a truly engaged, repeat user. This "penny gap of engagement" is the most critical early milestone to overcome for long-term success.
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.
In industries dominated by legacy players for decades, buyers lose the 'muscle' to evaluate new vendors. If you see low initial pull despite a strong value proposition, it may mean you need to educate the market on how to buy again, not that your product is wrong.
Instead of broad surveys, interview 10-12 satisfied customers who signed up in the last few months. Their fresh memory of the problem and evaluation phases provides the most accurate insights into why people truly buy your product, allowing you to find patterns and replicate success.
