About

Fewer things, done well.

Petros Group is an AI-powered mobile app studio founded to build apps and tools that solve real problems. We develop using agentic AI tools including Claude Code and other frontier models, which lets us ship faster and build with more depth than traditional development. Each product we make focuses on a specific problem and solves it properly.
