I've tried everything on the market and ProductBoard is the ONLY one that has stuck. I live in it every day. I've got Zapier zaps sucking in feedback from all over the place, and now with the Feedback Portal they unveiled, I'm able to provide transparency internally without frying non-dev non-designers minds with making them go into Jira (or even Trello I've found is TMI/confusing for people).
We've been using productboard to build our MVP and it helped us to get everybody on the team on board with what we're building and kept us focused. I love that productboard helped us also gather feedback from different sources (Intercom, emails and various conversations) so now we're processing the user feedback and planning our next product improvements - all in one tool. That's just the best!
Brilliant for managing all your project backlogs in a Kanban fashion. Including a list for the DIY tasks around the house.
As a Marketer I use this daily to manage workflow, sort ideas around future content and prioritize my activities. My team collaborate and report using handy integrations with Google and we use it as a Customer service and Sales script repository to store links to docs and how-to videos.
Trello has helped me organize my projects for a while now. Since I work as a software engineer. An example of my boards is sort of where I create tasks then I classify them according to their current position on the sprint. For example I have tasks in different cards such as Icebox, Backlog, Current Iteration and Done. I have set deadlines all ranging from 2 weeks to someday :(. Overall a great product!
