About Us
Anthony Greene
Founder & Chief Executive Officer
Anthony Greene is the Founder and CEO of AI Stack42. He built the firm around a clear thesis: AI leadership requires more than technical literacy — it demands operators who have owned real AI infrastructure, deployment, and enterprise transformation.
Anthony works directly with Boards and executive teams across Neocloud and Fortune 500 organizations to secure leaders capable of translating AI capability into measurable business outcomes. His approach centers on evaluating depth — not buzzwords — identifying executives who have operated inside AI-native environments and driven execution at scale.
He is focused on long-term strategic partnerships with companies investing heavily in AI infrastructure, digital transformation, and enterprise AI adoption.
