Graystar Labs

Graystarlabs is a senior software studio building mobile apps, full-stack web platforms, and AWS infrastructure for US startups, founders, and enterprise clients. Founded in 2019 and based in Bucharest, Romania, we work US business hours and deliver production-grade systems without the overhead of a traditional agency.

Our core stack covers iOS (Swift, SwiftUI), React Native, full-stack web, and AWS (CDK, EC2, infrastructure-as-code). We bring 15+ years of hands-on engineering experience across consumer apps, healthcare platforms, music education, and enterprise mobile — including shipped products in the App Store and zero-downtime migrations of production systems.

We integrate modern AI development tools (Claude, Cursor, GitHub Copilot) deeply into our workflow, which is how a small senior team consistently ships at the pace of a much larger one. Every project is led by an engineer who codes — not a project manager translating between you and a junior team.

Whether you need a new mobile app launched, a legacy system migrated to AWS, or a long-term technical partner for an ongoing product, we work as an extension of your team and care about your business succeeding past the engagement.
