Work With Us
We build AI tools and ship research. Let's build something together.
What We Do
2389 Research is a Chicago-based lab that builds AI agent infrastructure, developer tools, and applied research. We ship products, write about what we find, and open-source what we can.
We work with teams who want to put AI agents to work — not as demos, but as real tools that ship.
AI Agent Development
We design and build agent systems that handle real workflows: code generation pipelines, document processing, multi-agent coordination, and human-in-the-loop orchestration.
Dark Factory Development
We build headless software factories — pipeline runners where agents do the coding, testing, and shipping while humans focus on specs and review. Multiple independent implementations of the same architecture, converging on DOT-graph pipeline definitions that make agent workflows inspectable and repeatable. Lights-off development, where the interesting artifact isn’t the code — it’s the pipeline graph.
Tool Building
CLI tools, MCP servers, Claude Code skills, browser automation — we build the connective tissue between AI models and the work people actually do.
Research
We publish what we learn. Our blog covers experiments in progress, and our products grow directly from research findings.
Connections
Products, writing, and ideas — and how they link together.

Get in Touch
We're a small team that ships constantly. We like people who build things, break things, and write about it. If that sounds like you, say hello.
