We use what
we build.

Cascadia builds and runs AI-native businesses. Cascadia Software is our first operating business: a studio building the agent systems we use ourselves.

Every system has a person accountable for it. Accessibility, clear ownership and human checkpoints are part of the build.

One team.
The whole product.

From the first interaction to the systems behind it.

Product design

Research, information architecture, interaction design, and design systems. Accessibility starts with the first screen.

Engineering

Production TypeScript, React, and Next.js, with Storybook, design tokens, and build pipelines.

AI systems

Agents connected to your existing tools. We choose frontier, open-weight, or local models for the job.

Two ways to work together.

Design engineering

One person takes your interface from design to production code.

Design systems · Product design · Accessibility

AI systems

Agents handle manual operations using frontier, open-weight, or local models. The model choice stays reversible.

Agentic automation · Agent-backed design · Product factories
