CEO at Greelow
Argentina
Summary
👤
Senior🎓
Top SchoolJavier Holcman is a founder and technology leader with over a decade of hands-on engineering and product delivery experience, currently scaling Greelow as CEO while acting as Fractional CTO/CAIO for startups and scale-ups. He built Greelow from 2017 into a 38-engineer agency across Buenos Aires and Miami that delivers production software and AI integrations for clients like Banorte, Wallbox, McDonald’s and Deepak Chopra. Javier’s specialty is taking AI pilots off the demo screen and into scalable, product-integrated systems—designing agents, selecting stacks (Claude Code as a standard), and measuring business impact. His background spans enterprise architecture and mobile/web engineering roles at companies such as Nestlé, Trimble and e-Builder, giving him deep experience in both legacy modernization and modern AI-native builds. He combines operator instincts with an engineering playbook for hiring AI-native teams and deciding what to rebuild versus what to leave alone. An uncommon asset: he pairs agency-scale delivery muscle with fractional CTO advising for teams of 5–200 focused on turning AI experiments into measurable business outcomes.
