Our design perspective: Feedforward over reviews
15Five has done pioneering work helping managers hold structured conversations. For traditional corporate hierarchies with formal promotion ladders, structured review platforms serve an important administrative purpose.
However, for modern product, engineering, and remote squads, heavy evaluation forms can trigger dread and defensiveness. Following legendary executive coach Marshall Goldsmith's research, Mellowe separates appreciation and coaching from salary evaluations. Our Voluntary Peer Feedforward model allows teammates to proactively solicit advice on future challenges—creating an environment of mutual trust rather than managerial surveillance.
If your organization needs formal 360 review software and OKR frameworks, 15Five is a mature, capable platform. If your team wants collaborative 1:1 check-in rooms, burnout prevention, and peer gratitude tied seamlessly to Slack, Mellowe is built for you.
