About 404 // Software crafters

404 is a software development company that designs and deploys Apps and AI agents integrated into real production systems — not prototypes. Based in Buenos Aires with 15 years of experience building mobile, web, and AI-powered products, our software runs banking and fintech infrastructure across Latin America, reaching +70 million users worldwide.

We apply that same production-grade rigor — secure, scalable, always-on — to applied AI: LLMs, RAG, and conversational agents that plug directly into our clients' systems. Internal and external quality are our top priorities, from simple and elegant code to the flows and interfaces people actually use.

Nearshore team based in Buenos Aires, working in your timezone, in English and Spanish.
