We are making a collaborative outlining tool that will help product owners facilitate decisions and discussions across the lifecycle of a feature.
Right now these discussions happen as unstructured comments all over the place, e.g. On cards on a roadmap in Trello, on feature spec in a Google doc, on designs in an InVision prototype, on JIRA tickets, and in different channels in Slack.
Our tool focuses making it easy to keep track of open questions and to facilitate structured discussions where the team evaluate options and their pros and cons and come to good decisions.
We are still in heavy product development but have a working product that gets positive feedback from UX interviews and the pilot projects we are running.
