You're very early. Paying customers are the most important thing for you to get.
However, it doesn't matter how much the first 1% (of your target market) pay, now or in the future. (If you're successful, they're only 1%. If you're not successful....)
Let's assume that success is 100k-1M paying customers.
Anything that gets in the way of someone being one of your first 1,000 paying customers is bad. Not telling the price upfront is one such thing. Trying to charge "market/what it's worth" is another.
Now is not the time to optimize pricing. In fact, you should tell the first 1-2% of paying customers that they will always and without any effort on their part get better pricing than anyone else going forward.
Yes, you should ask them what they think other people should/would pay....
