Built AI-native
A developer with quadriplegia shipping production software with a team of AI agents.
Our founder controls the mouse with the right foot and types with a chopstick held in the mouth. Instead of typing code by hand, the founder directs multi-agent workflows built on Claude Code — designing, reviewing and shipping.
For us, accessibility is not a checklist. It is a precondition. We don't build tools we can't use ourselves.
- Lived experience as requirements — over a decade running an Independent Living Center shapes every feature.
- Accessible by default — WCAG 2.1 AA, full keyboard navigation and screen-reader support.
- Privacy by design — minimal collection and strong encryption of disability-related data.
- Open source first — tools that can be public goods are released under MIT.
About
Accessibility isn't an add-on; it's where design begins. ATIT (all that IT for disabled) builds software that expands the independence and rights of disabled people. Lived experience is our requirements analysis, and every product we make is one we use ourselves first.
We are currently preparing to incorporate in the United States.
