Why Engineering Leaders Choose Greelow
AI-Native Engineers
Our engineers use Claude Code, GitHub Copilot, and Cursor daily. They don't just write code — they architect with AI as a co-pilot, delivering in weeks what used to take months.
Deep Vertical Expertise
Fintech, Healthcare, and AI/ML — not generalists. We've built neobanks, medical platforms, and RAG pipelines. Your engineers understand your domain from day one.
Senior-Only Teams
No junior farms. Every engineer has 5+ years of experience and proven track records in US companies. We screen for autonomy, not just syntax.
Your Timezone, Your Team
Buenos Aires is 1 hour from EST. Our engineers work your hours, join your standups, and feel like teammates — not vendors.
Engineering Leadership Included

Zero Friction
