Straightforward, affordable, Slack-native, effective way to run performance reviews

We were looking for something simple, affordable and genuinely integrated with Slack, having had some frustrating experiences with other providers in the past. Windmill has been exactly what we needed!<br><br>It’s really easy to use, both from an admin perspective and for the wider team. The Slack integration makes a huge difference, and Windy’s conversational approach to gathering feedback makes the whole process feel much less formal and cumbersome than traditional performance review tools.<br><br>I also really like the calibration features, which have helped us introduce a bit more structure and consistency to our reviews without overcomplicating things.<br><br>Getting set up was incredibly straightforward, and being able to properly try it out on the free tier before committing was a big plus. The team have also been brilliant, really responsive, open to feedback and genuinely helpful throughout.

Faster, Data-Driven Reviews With Minor Growing Pains

I think Windmill is great. I like having a central place for managers to give and track feedback and for me to track performance. The manager review flow makes writing reviews better and faster, so we’ve made quarterly reviews a standard part of our cadence because the process is that smooth. Reviews feel more data-driven, with less recency bias because Windmill pulls in Granola notes from 1:1s throughout the review period. It took performance reviews from a dreaded blank-page writing exercise to something grounded in real, aggregated context, making our team’s reviews faster to write and noticeably higher quality. I’ve replaced all other 1:1 and performance software with Windmill, the initial setup was very easy, and the team is incredibly responsive to feedback and helpful when questions come up.
