Developers who've never shipped paid products (or are too scared to charge) miss a critical insight:

Real users who pay don't just tolerate your product—they actively report bugs, suggest features, and evangelize to their network. Payment creates skin in the game. Free users ghost you. Paying users become co-builders.

The fear of charging is often just imposter syndrome disguised as user empathy. If your tool solves a real problem, someone will pay. And those paying users will give you the signal you need to iterate faster than any free beta ever could.
