15Five

15Five is a performance management platform that combines continuous feedback tools with AI features aimed at making reviews and check-ins less of a chore. Its core products include weekly check-ins, Best-Self Reviews (AI-assisted self and manager reviews), OKR and goal tracking, engagement surveys, and manager coaching tools that surface talking points and flag disengagement risks before they show up in attrition numbers. The AI layer helps managers draft feedback, summarize check-in themes across a team, and get nudges on who might need attention.

It's built for HR leaders and people managers at mid-size companies who want an alternative to the once-a-year review cycle, giving them ongoing signal on morale and performance instead of a single annual snapshot. Over 3,000 companies use it, spanning tech, healthcare, and professional services, and it integrates with Slack, Microsoft Teams, and common HRIS systems so check-ins and reviews fit into existing workflows rather than becoming a separate destination employees have to remember to visit.

What sets it apart from pure OKR trackers or survey tools is that it bundles the review, goal-tracking, engagement, and manager-coaching pieces into one system, with the AI aimed specifically at the manager's side of the job (writing feedback, spotting patterns) rather than just automating employee self-assessments.
