How to manage your product feedback-loop?

As a product team, we received plenty of feedback from sales, customer success, marketing, and especially from the CEOs of the companies where I worked.

We have tried to manage feedback using spreadsheets but have failed. We also tried to include non-tech teams in the task management tool to keep them in the feedback loop in the same place as development and product teams. There are so many other ways I don’t even remember them...

This is how the idea of Producter.co was born.

I’m really curious how you manage user feedback, and is it possible for you to keep stakeholders in the feedback loop? or do you handle all these manually?
