Kaigo Health (YC F25) deploys AI voice agents for elderly outpatient follow-up, scaling post-visit check-ins 100x for Medicare providers who currently have near-zero between-visit care.
Kaigo Health is a healthcare AI startup founded in 2025 and headquartered in San Francisco, built to address one of the most persistent gaps in outpatient elderly care: the near-complete absence of structured follow-up between clinical visits. The company was accepted into Y Combinator's Fall 2025 batch, a validation of its founding team and market thesis at a very early stage. Kaigo targets the Medicare provider ecosystem, where outpatient follow-up is both a quality metric and a reimbursement driver under value-based care arrangements.\n\nKaigo's platform deploys AI voice agents that conduct follow-up calls with elderly patients between clinical encounters, checking on medication adherence, symptom changes, and overall wellbeing in a conversational, accessible format appropriate for older adults who may be less comfortable with app-based or text communication. The system scales these follow-up touchpoints by 100x compared to what a human care coordination team could accomplish at equivalent cost, dramatically expanding the reach of providers who want to improve patient engagement without proportional staffing increases.\n\nThe company is entering a market shaped by twin pressures: an aging US population driving record Medicare enrollment and a care workforce shortage that makes scaling high-touch care coordination through humans alone economically unsustainable. AI voice agents are increasingly recognized as a practical solution to this gap, particularly for the elderly population where voice interaction is natural and phone calls remain a trusted communication channel. Kaigo's early YC backing positions it alongside a cohort of companies building AI infrastructure for the future of value-based elder care.
Indianapolis BCBS managed care (NYSE: ELV) ~$175B FY2024 revenue; Anthem renamed 2022, BCBS exclusive in 14 states, Carelon health services, Medicaid/MA medical cost pressure competing with UnitedHealth and Cigna.
Elevance Health, Inc. (formerly Anthem, Inc.) is an Indianapolis, Indiana-based managed care and health services company — publicly traded on the New York Stock Exchange (NYSE: ELV) as an S&P 500 Health Care component — providing health insurance plans under the Blue Cross Blue Shield brand in 14 states (Indiana, Georgia, California, Colorado, Connecticut, Kentucky, Maine, Missouri, Nevada, New Hampshire, New York, Ohio, Virginia, Wisconsin), Medicare Advantage, Medicaid managed care, and commercial employer-sponsored health plans through Carelon (pharmacy and behavioral health services — formerly IngenioRx) to approximately 47 million medical members through approximately 100,000 employees. In fiscal year 2024, Elevance Health reported revenues of approximately $175 billion (predominantly premium revenues from employer-sponsored and government-program health plan members), with operating income under pressure from medical cost increases in the Medicaid segment (post-COVID health utilization normalization causing medical costs to exceed Medicaid actuarial pricing expectations set during the pandemic period of reduced care utilization). CEO Gail Boudreaux has executed the company's transformation from Anthem to Elevance Health (rebranded June 2022) — reflecting the broadened value proposition beyond health insurance into health services: Carelon Services (behavioral health, pharmacy benefit management, utilization management, home health services for both Elevance and external health plan clients) represents the strategy of building a health services ecosystem that retains value within the Elevance enterprise rather than paying external PBMs, behavioral health managers, and care management vendors.
