Performance reviews that people actually like.
By syncing with your tools 
and talking to your teams, Windy 
gives managers the real picture, employees clarity, and HR teams receipts instead of guesswork.

The most important part of my job is people management. I used to really dread a lot of the chores that came with it, but Windmill makes it a snap for me and my team.
Bryan Rutcofsky

Windmill has been an incredible tool in helping our team deliver, receive and process feedback. Windy, their AI bot, makes providing feedback painless and the "real time" requests eliminates the recency bias of every other HR/Performance Management solution we've used in the past.

Backed by enterprise-grade security and scale
Security isn’t an add-on at Windmill. It’s integral to every layer of our system. We use industry-standard encryption and secure infrastructure to protect your data.
Integrations
Your everyday tools seamlessly integrate with Windmill
Windy always knows what's going on. Stay informed without constantly checking in, and get timely insights when you need them.
Frequently asked questions
Can Windmill integrate with our current tools like Jira, Confluence, HubSpot, Google, or Asana?
Yes, Windmill integrates your existing tools - our integrations are available on the 'Integrations' page. These integrations are used to aggregate data about work activity, collaboration, projects, and more, allowing the platform to deliver robust performance insights and feedback cycles.
How does Windmill encourage employee engagement?
Windmill is built around the employee experience. We achieve high engagement by meeting employees where they already work (in Slack) and making feedback, 1:1 prep, and reviews effortless. Simply by chatting with Windy, employees can participate without added logins and dashboards. The result is steady, lightweight engagement that feels organic, not forced.
How does Windmill handle privacy and security?
Windmill is SOC 2 Type 2 compliant. Windy respects native privacy settings of every integrated system. Our Trust Center is linked on our website under "Security".
Is Windmill meant to replace our HR system?
No, this product is not intended to replace HR systems used for payroll, benefits, or compliance. It is designed to replace or enhance your performance management module or software.
How does Windmill compare to other vendors like Culture Amp, Lattice, or 15Five?
Windmill is lighter-weight and more in the flow of work than Culture Amp, Lattice, or 15Five. While other platforms require logging into a separate system, Windmill runs directly in Slack and captures feedback, recognition, and 1:1s as work is happening—so adoption is much higher. We focus on real-time collaboration and continuous improvement, not just periodic reviews or survey cycles.
Are admins able to see all responses to questions sent out by Windy? What are the privacy settings?
Visibility in Windmill is determined by your org chart and role-based permissions, not by broad access. Managers see data for their direct reports, HR/People Ops can access organization-wide insights if configured. However, anonymous surveys and responses always remain anonymous. Every workflow clearly shows who can see what, so data access is always transparent and intentional.
How does Windmill work in Slack?
Windy, our AI agent, interacts with your team via individual Slack conversations. From surveys, to 1:1 prep, to performance reviews, employees participate simply by responding to Windy in the Slack. Once responses are complete, Windy compiles the information into clean, insightful reports, helping keep teams aligned.
