    About LiveLong

    Healthcare that moves
    as fast as you do.

    Making preventive blood testing simple, fast, and physician-guided for people who want clarity before symptoms appear.

    Built in Amsterdam, for a city that hates waiting.

    Dutch healthcare is famously good, and famously slow to act preventively. If you want a full blood panel in the Netherlands today, you ask your GP, wait two weeks for an appointment, wait another two weeks for results, and often get "everything looks fine" without much explanation.

    For the 25-to-45 crowd (expats, professionals, and health-conscious people who read their own research), that's not enough. You want the actual numbers, you want them quickly, and you want a doctor to explain what they mean.

    We started LiveLong to close that gap: preventive blood testing that's simple, fast, and physician-guided. Book a panel, get your draw at a partner location, and see doctor-reviewed results on your phone within 48 hours, in plain language, in English or Dutch.

    Prevention isn’t expensive. Reaction is. Every chronic disease we catch at marker-level instead of symptom-level is years of life back.

    Our principles

    What we believe

    Your data is yours.

    Full history, exportable, forever. No lock-in, no dark patterns.

    Doctors, not chatbots.

    Every result is read and signed off by a Dutch-registered physician.

    Plain language.

    If we can't explain a marker in one sentence, we haven't earned the right to test it.
