Connecting people with life-changing research
We believe everyone deserves access to tomorrow’s treatments, and that their time is worth paying for.

Close the gap between patients and the studies that need them
Every year, thousands of clinical trials are delayed or cancelled because they can’t find enough participants, while millions of people who would gladly join never hear about them. Clover exists to fix that mismatch with a platform that’s as simple as booking a flight and as trustworthy as your own doctor.
We also think it’s time to be honest about compensation. People join studies to help science, to access new treatments, and yes, for the stipend. We put all three on the table.

Our story
Why we built Clover
Clover started in 2020 after our co-founder’s mother received a rare diagnosis. There was a promising trial two states away. Finding it took six weeks of phone calls, outdated registries and PDFs written for scientists.
We thought: if it’s this hard for a family with a nurse and a software engineer in it, it’s impossible for most people. So we built the tool we wished we’d had. Clear listings. Plain language. A human to call. And the compensation printed right on the card.
Founded in 2020
Headquartered in San Francisco, with guides across every US time zone.
Clinicians, engineers, patient advocates
Half our team has worked inside a research site. All of us have been patients.
Partners in all 50 states
From academic medical centers to community clinics, we list studies where people actually live.
Our values
What we won't compromise on
Participants first
Every product decision starts with one question: is this good for the person joining the study?
Trust and safety
We list only IRB-approved studies, and we hold our data practices to HIPAA standards and then some.
Research for everyone
Medicine works better when trials reflect the people it serves. We work to remove the barriers that keep communities out.
Honest about money
Compensation is part of why people join. We put it up front, in plain numbers, instead of hiding it in the fine print.
