Perform vs. Windmill

Perform by Confirm (formerly Confirm HR) Perform (formerly Confirm HR) is an AI-powered performance management platform that helps organizations run fairer, faster performance cycles and coach managers before problems surface, not after. Most performance tools only capture what people say about themselves. Perform goes further, using Organizational Network Analysis (ONA) to map how work actually flows across a company, surfacing who's ready, who's at risk, and where bias might be creeping into decisions.

Windmill is the first performance review system people actually like. Powered by AI, it synthesizes all your 1:1 conversations, project work, and feedback throughout the year into reviews that write themselves. Employees respond to quick prompts in Slack instead of staring at blank forms trying to remember six months back. Managers walk in with the full story. HR finally has a process that doesn't need constant nudging. Companies using Windmill cut down time by 83% per cycle time and report 93% employee satisfaction with the process.
