OneChair Dev
Building Software 97 percent faster
OneChair.dev is an AI-orchestrated software development company built around a single premise: enterprise-grade software should not take months to deliver. Powered by OneSpark — a proprietary system deploying 85+ specialized AI agents in parallel — OneChair collapses the traditional development lifecycle into days, running architecture, frontend, backend, and QA simultaneously rather than sequentially.
The result is custom software delivered up to 97% faster than a traditional agency, at a fraction of the cost, with zero compromise on compliance or code quality. Every build ships HIPAA, GDPR, ADA, SOC 2, and WCAG ready — with clean, fully documented, client-owned code and a live staging environment from day two.
OneChair serves founders, startups, and mid-market to enterprise teams through two models: fixed-price custom software builds and embedded technical partnerships where OneChair operates as the client's full engineering team on an ongoing basis.
