Koltin is a Mexican insurtech company that provides private health insurance and preventative healthcare services specifically designed for adults aged 50 to 85 years old. Founded in 2020 by Eduardo Ortiz Reynaga and Carmen Rosillo, the company is headquartered in Ciudad de México and launched commercial operations in 2022. Koltin positions itself as the first company in Mexico to offer comprehensive private health insurance coverage to seniors, a demographic that has historically been underserved due to prohibitively expensive premiums. The company offers health memberships that combine major medical expense insurance underwritten by BBVA Seguros Salud with proactive, personalized care delivered through a team-based approach. Members receive access to virtual consultations via WhatsApp and phone, in-person annual check-ups, preventive services from medical specialists including geriatrics and nutrition, and coverage through a national hospital network. Unlike traditional insurance products, Koltin emphasizes preventive care to reduce chronic conditions and improve health outcomes for aging populations. The company has issued over 150 million pesos in insurance premiums since its commercial launch and maintains a customer retention rate above 90 percent. In September 2024, Koltin raised $7.3 million in Series A funding led by Left Lane Capital, bringing total funding to approximately $10.8 million from investors including 500 Global, Graph Ventures, Mucker Capital, Catalyst Fund, and Addem Capital. The company currently employs approximately 140 people and has opened its first physical location, Casa Koltin, in the Condesa neighborhood of Mexico City. Koltin targets middle-income families seeking affordable healthcare solutions for elderly relatives and aims to expand its services throughout Mexico.
