HOUSTON, TX — January 15, 2025 — Lone Star Digital Health, a Houston-based healthcare technology company, announced today it has closed a $15 million Series A funding round to accelerate the expansion of its artificial intelligence-driven patient care platform across Texas and neighboring Gulf Coast states. The round was led by Austin-based Mercury Health Ventures, with participation from existing investors including Gulf Capital Partners and several prominent Houston-area hospital systems. The company plans to deploy the capital toward product development, regulatory compliance infrastructure and a significant expansion of its clinical partnerships team. Founded in 2021, Lone Star Digital Health connects underserved rural and suburban patients with primary care providers through a proprietary telehealth platform that uses predictive analytics to flag high-risk patients before conditions escalate. The company currently serves more than 85,000 patients across 34 Texas counties and reports a 31% reduction in preventable emergency department visits among its active user base. "Texas has nearly 5 million residents living in medically underserved areas, and closing that gap requires more than traditional telehealth," said CEO Dr. Maria Castillo. "This funding allows us to build the clinical intelligence layer that turns data into timely, life-changing interventions." The company expects to double its county footprint by Q4 2025 and anticipates crossing the 200,000 active patient threshold within 18 months. **About Lone Star Digital Health** Lone Star Digital Health is a Houston, Texas-based digital health company dedicated to closing healthcare access gaps through AI-powered telehealth solutions.
