About Us
Global footprint, local engagement
Since launching in Chile in 2005, ALTO has expanded globally to five countries and over 150 cities. Despite our international reach, we focus on local impact with hundreds of ALTO team members embedded in communities across the United States. By taking a community-based approach, we support retailers of all sizes—from small businesses to major brands—to create safer stores together.
