then may be you can reasonably increase pricing if it’s required, or may be do A/B testing.

But since you seem to be in the startup phase, if I were in your place (even though I don’t know what your product is), I would focus on acquiring more lower-paying customers. You can always ask them to pay more at any time. Once my product has a reputation on par with my competitors and achieves feature parity with them, then I would think about increasing pricing.

what is the reason behind your existing customer is using your product ? is it pricing or something else?

is your product equal or better than your competitor ? because when you close the price gap then customers will have one less factor to consider which is pricing between yours and their product.
