There is a range of methods to gather feedback, including user interviews, surveys, A/B testing, social media monitoring, and customer support interactions.
We also leverage product analytics to gain insights into how users are interacting with our product and where they may be encountering issues.
I'm using a few methods:
Customer calls
Feedback survey from newly registered users
Discord community
Public roadmap
G2 reviews
The best ones are simple surveys and customer calls but we have a lot of users so it depends on which stage is your product in. Are you just starting?
