Leona Health Secures $14M to Bring AI-Powered WhatsApp Care Management to Latin America

Leona Health, an AI healthcare communications startup founded by former Uber Eats Latin America GM and ex-Rappi COO Caroline Merin, has raised $14 million in seed funding to modernize doctor–patient messaging across Latin America. The round was led by Andreessen Horowitz, with participation from General Catalyst, Accel, Kate Ryder, David Vélez, and Simón Borrero.

Leona delivers an AI copilot integrated with doctors’ existing WhatsApp workflows, allowing physicians to triage, prioritize, and respond to patient messages through a dedicated mobile app rather than unmanaged chat threads. The platform uses AI to surface urgent cases, suggest responses, and delegate routine requests to care teams.

Now live across 14 countries and 22 medical specialties, Leona is expanding toward autonomous scheduling and intake, addressing a critical productivity and burnout challenge for physicians in WhatsApp-first healthcare markets.
