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.
Washington DC life sciences instruments (NYSE: DHR) at $23.9B FY2024 revenue; Cytiva bioprocessing, Beckman Coulter diagnostics, biopharma destocking recovery, 2025 core revenue +3% guidance competing with Thermo Fisher.
Danaher Corporation is a Washington, D.C.-based global science and technology company — publicly traded on the New York Stock Exchange (NYSE: DHR) as an S&P 500 Health Care component — developing, manufacturing, and marketing analytical instruments, reagents, consumables, software, and services for life sciences research, clinical diagnostics, and environmental monitoring through approximately 65,000 employees worldwide. In fiscal year 2024, Danaher reported revenues of $23.9 billion (flat year-over-year) with non-GAAP core revenue declining 1% as the biopharma sector's inventory destocking cycle continued, with Q4 2024 revenue of $6.5 billion (+2.0% reported, +1.0% core) representing an inflection toward recovery, generating $6.7 billion in operating cash flow and $5.3 billion in free cash flow. Danaher guided 2025 core revenue growth of approximately 3% — marking the expected return to growth as biopharma customers who destocked pandemic-era bioprocessing supply surpluses return to normalized purchasing. CEO Rainer Blair leads Danaher's post-spinoff strategy: in September 2023, Danaher separated its Environmental & Applied Solutions segment as Veralto Corporation (NYSE: VLTO), creating two independent public companies — Danaher (pure-play life sciences and diagnostics) and Veralto (water quality and product identification). Danaher's current portfolio centers on bioprocessing (Cytiva's bioreactors, membranes, single-use manufacturing for drug production), clinical diagnostics (Beckman Coulter chemistry and hematology analyzers, Radiometer blood gas analyzers, Cepheid molecular diagnostics), and life sciences research instruments (SCIEX mass spectrometry, Leica Microsystems microscopy).
