The research process

    1. Share your health data

    2. Tell us what types of studies you're interested in using your profile settings.

    3. We'll match you to studies and notify you about relevant opportunities. You can also view our open studies at any time.

    4. You review study details and decide whether to participate.

    5. If you request enrollment, we coordinate everything from there.

  • If you agree to a biospecimen study requiring collection:

    1. We schedule a convenient time for you.

    2. A licensed clinician comes to your home.

    3. They collect the required sample (blood draw, swab, etc.) The process typically takes 10 minutes or less

    4. Your sample is securely transported to the research lab.

    5. You receive your compensation.

  • We’re expanding coverage nationwide, but availability depends on your location and the specific study. Most studies can be done from anywhere in the United States.

  • You can stop participating at any time, for any reason, with no penalty. You can:

    •  Decline individual study invitations

    •  Pause notifications temporarily

    •  Withdraw from active studies

    • Delete your health data

    •  Delete your account entirely

    Your participation is always voluntary and on your terms.

  • No! Unlike clinical trials, our research studies are observational. You continue your current treatment plan exactly as prescribed by your doctor. We’re studying real-world health experiences, not testing experimental treatments.

  • No. Your participation in research studies through our platform does not affect your health insurance coverage, rates, or eligibility in any way. This information is completely separate from your insurance.

  • That’s exactly what makes you valuable to research! Rare disease patients are especially needed for medical research. We actively seek participants across all conditions, including rare and ultra-rare diseases. Your unique health journey could be the key to breakthrough discoveries.

  • Yes! Healthy participants are essential for research as control groups and for studying normal biological processes. We have many studies specifically seeking healthy donors.


  • We support research across all major therapeutic areas:

    •  Autoimmune conditions

    •  Cardiology

    •  Dermatology

    •  Infectious diseases

    •  Mental health

    •  Metabolic disorders

    •  Neurology

    •  Oncology

    •  Rare diseases

    •  Respiratory conditions

    •  Women’s health

     And more!

Medical & health questions

  • Your participation directly contributes to medical research breakthroughs:

    •  Helps researchers understand diseases better

    •  Contributes to development of new treatments

    •  Advances personalized medicine

    •  Could benefit you, your loved ones, and others with similar conditions

    •  Accelerates the path from research to real-world treatments

  • Absolutely! We encourage referrals and offer bonuses when people you refer sign up and participate. It’s a great way to help your community contribute to research while earning additional compensation.

  • Here are the key differences:

    Clinical trials:

    •  Test experimental treatments

    •  Require you to change your current treatment

    •  Often require frequent site visits

    •  Long-term commitment (months to years)

    •  Strict protocol requirements

    •  May involve placebos or unknown treatments


    Our research studies:

    •  Observational (no experimental treatments)

    • Continue your current care unchanged

    • Participate from home

    • Short time commitment (average 10 minutes)

    • Flexible participation

    • You know exactly what’s involved upfront

    • Both are valuable to medical science, but our platform offers a low-risk, convenient way

    • To contribute without disrupting your life or health care.
