Automatic 1:1 agendas from Slack threads are a lifesaver.
Great for performance reviews without the memory guessing game.
Setup took a couple of days to get right.
Needs more flexible reporting templates.
AI-synthesized perspectives grounded in live site inspection, pricing structure, and category benchmarks — presented as editorial viewpoints rather than individual customer testimonials.
An in-Slack agent that runs check-ins, collects peer input, and drafts performance reviews from evidence it gathered during the quarter.
Agendas are assembled from the week's actual work, with space for the employee to add what is on their mind before the meeting.
Windy notices when two people finish something together and asks how it went, so feedback arrives in days rather than six months later.
Committee members get a bias-flagged pre-read and a rating grid where every placement can be traced back to supporting evidence.
Connects to Slack, Jira, Figma, Notion, Google Workspace, Asana and more than 32 other tools so evidence is collected automatically.
Windmill takes aim at the part of performance management everyone dreads: reconstructing six months of work at review time. Rather than asking managers to remember, it builds an evidence trail continuously. Windy reaches out in Slack after someone joins, asks peers how a finished project went, and pulls the week's real activities into a ready-made 1:1 agenda, so the conversation starts from facts instead of awkward silence.
At the end of a cycle, the platform drafts the review itself. A rating comes with the underlying evidence items and peer reviews attached, which means managers review the evidence rather than rebuild the quarter from memory, and employees get a reminder of their own accomplishments. That same traceability carries into company-wide calibration, where committee members receive a pre-read flagging potential bias and inconsistent ratings, and can trace any decision back to the evidence behind it.
Windmill covers the broader performance stack too: 1:1s, agentic employee onboarding that meets new hires on day one, continuous feedback, pulse surveys, and analytics. It connects to the tools teams already use — Slack, Jira, Figma, Notion, Google Workspace, Asana, and dozens more — so the evidence exists without extra data entry. The company publishes SOC 2 Type II and GDPR compliance claims, and pricing is handled through a demo conversation.
Replace spreadsheets and nagging with drafted reviews and pre-reads, so committees get decision-ready material and cycles close faster.
Walk in with an auto-generated agenda built from shipped work, PR feedback, and blockers, plus anything the employee added themselves.
Windy messages new joiners in week one, surfaces gaps before the first 1:1, and gives later hires a repeatable day-one walkthrough.
Review a grid of ratings with bias flags and linked evidence items, making promotion and pay decisions easier to defend.
