Navigating chronic illness is an isolating and lonely process which ultimately reduces medical adherence and adversely impacts outcomes. There are over 100 deadly chronic conditions as 1 out of 2 Americans is currently living with at least 1 chronic condition. The US healthcare system has over $1 trillion dollars in direct costs. Medical adherence rates for therapeutic programs and medicine are only 50% because patients feel lonely, isolated, and unsupported in their chronic illness journey. Reviving Mind is an in-network telehealth provider that improves clinical outcomes and program adherence for the senior medicare and medicare-advantage population that is plagued with loneliness and chronic illness. This is done through a novel and proprietary clinical program and technology platform that integrates virtual, private, curated, and professionally led groups that scale up to 8-patients with individualized and goal oriented lifestyle medicine coaching that is automated but managed by a licensed provider. Scaling rapidly across the United States.

FlyCode Dunning & Payment Management AI that helps subscription merchants maximize revenue. We reduce passive churn by managing payment failures intelligently. We’re Jake, Etai, and TD and we’re building FlyCode.
