About SF AppWorks

SF AppWorks is a boutique AI-augmented software engineering agency founded 15+ years ago with US leadership in San Francisco and an engineering team in Cluj, Romania. They specialize in agentic AI architecture, AI-augmented development workflows, and QA as AI safety. Notable clients include Yum! Brands, J. Crew, West Elm, Williams Sonoma, Google, AARP, and Vanguard. A West Elm PWA build delivered an 8% revenue-per-user increase.

Who SF AppWorks Is Best For

SF AppWorks is a strong fit for retail, financial services, and consumer brands that need senior-level software engineering with AI-augmented workflows. Their boutique size means clients get direct leadership access, while their Romanian engineering team delivers at competitive rates with US timezone overlap. Best for companies that want a selective, high-accountability partner rather than a large commodity vendor.
