How did you figure out what to charge for your first product?

Not looking for the "charge more" take, genuinely curious about the actual moment.

Did you pick a number and see if it stuck? Copy what a competitor was charging? Wait until someone paid without flinching?

For most founders I've talked to, the first price was either a guess or an anchor they got stuck with for way too long. Real pricing data only shows up after you've closed enough deals to see a pattern and by then you've probably left money on the table.

What was your process, and would you do it differently?
