Kaigo Health vs Thermo Fisher Scientific
Side-by-side comparison of AI visibility scores, market position, and capabilities
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.
About
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.
