OneChair.dev

OneChair builds custom software 97% faster than traditional development.

For founders and teams who can't afford to wait months for a working product, OneChair is the AI-orchestrated development house that delivers enterprise-grade software in days — not quarters.

At the core of every build is OneSpark, OneChair's proprietary AI development system. OneSpark deploys 85+ specialized AI agents working in parallel — handling design, backend, frontend, and testing simultaneously, while a senior engineer oversees every line of code. The result is a development process that condenses months of work into weeks, without sacrificing quality, compliance, or ownership.

The numbers speak for themselves: WingmanAI in 33 working hours. A full resource center in 30 working hours. These aren't outliers — they're the standard.

Every project comes with a fixed price, agreed before we build out your project. No hourly billing, no scope creep, no surprises. And from day two, your build lives on a live staging URL — so you can see it, test it, and share it as it takes shape in real time.

Whether you need a custom internal tool, a client-facing platform, or a full MVP, OneChair gives you startup speed with enterprise reliability.
