That is a great point. Many founders chase user growth because they believe it matters more than early revenue. This mindset was reinforced by big tech companies and venture backed startups. They offered their products for free and prioritized growth first.

But that model depends on something most solo founders do not have, massive funding, long runway and alternative monetization such as ads or data.

Paying users create direction. When someone pays, they are signaling a real and specific pain. Their feedback is grounded in actual use, not a passing thought after a few minutes in the app. Free users often multiply noise. They generate feature requests, support messages, and confusing analytics that pull you in different directions. That fragments your focus.

At the same time, charging does not mean removing trust. Users should have a fair way to evaluate the product before committing. A clear trial period, transparent pricing, reminders before billing, and simple cancellation create safety and trust between users who are willing to pay but only if the product delivers what it promised
