Builders · Overview
You're in your builder era.
First HR platform designed to empower the HR team with the tools to build what they want — without having to ask IT or keep buying vendor modules.
Build, don't buy.
Stop paying crazy prices for things you can build in a few hours with a tool designed to help you do that. We'll even show you how.
All in one.
Winslow comes with everything you need out of the box — and the tools to add anything else.
A note for the People team
For twenty years, HR has been the customer of someone else's opinions. That ends now.
Pick any HR system you've used. Workday, Rippling, Gusto, Justworks, ADP. You sat in a kickoff. Someone from implementation walked you through their data model, their fields, their workflows, their idea of what an onboarding looks like. You adjusted your company to fit their software. Then you paid them for the privilege.
That was the deal because the alternative — building your own — meant hiring engineers, designing a data model, writing UIs, integrating payroll providers, surviving SOC 2. Six engineers, two years, and you still wouldn't have an HR system. So People teams took the templates.
The deal is over. The same shift that let a two-person startup ship a B2B product in a weekend has come for HR. With an MCP server, a writable system of record, and an agent that can read your policies in plain English — the People team becomes the author of the system, not its customer.
Builder-first principles
Things other HR vendors won't give you.
Every product decision at Winslow rolls up to one question: does this make the People team more powerful, or does it make them more dependent? We pick more powerful, every time.
01
No gatekeeping
A real, writable database. Read it, write it, export it. No vendor lock, no black-box objects, no "raise a ticket" to get at your own records.
02
Agent-ready by default
Every Winslow capability ships through an MCP server. Your team's Claude, ChatGPT, Cursor read and write production HR data with no bespoke wrapper.
03
Your own agent in the cloud
Every Winslow customer gets a dedicated agent stack in the cloud. Or bring your own.
Flip the script
Winslow empowers HR so HR can empower everyone.
The whole HR-software story has been about the People team operating a tool and the rest of the company tolerating it. We think that's exactly backwards. Every employee at your company should be more productive because their People team chose Winslow — not just the People team itself.
Anyone at the company can ask Winslow to build them something. A custom workflow for a recurring task. A reminder that pings when a teammate's birthday or work anniversary lands. A dashboard for their direct reports' comp and tenure history. The kind of tools your team used to buy a SaaS subscription for — built in the same chat window they already work in.
- Custom workflows on demand
- Birthday + work-anniversary reminders
- Manager dashboards, built to order
- Recurring tasks, scheduled and tracked
- Ask anything of your team data
Start where it fits
Four surfaces. One platform underneath.
You don't have to commit to a way of building. The MCP, the REST/GraphQL API, and the agentic runtime all point at the same writable system of record. Pick the one that fits the problem in front of you.
MCP
Access Winslow anywhere
One server. Every capability. Hire, terminate, promote, run payroll, file taxes — exposed to your agent stack with the same auth that protects the admin UI.
API docs
Coming soon
REST + GraphQL. Versioned, paginated, webhooked. The MCP is a wrapper on this; nothing about your data is hidden behind a vendor-only surface.
Agentic Layer
Your agent in the cloud
Long-running, scheduled, event-driven agents that live next to your data. Comp review runs at 11pm Friday. Onboarding kicks off the moment an offer is signed. You write the skill, we run the runtime.
Stop fighting with your HR technology, start building with it.
Bring your stack. Bring your agent. Bring the workflow you've been waiting three procurement cycles for. Build the first one this week.
