We’re building the infrastructure that connects people to paid research.
Trials Arm is a marketplace for clinical research participation. Participants find studies, apply, and get paid. Labs post studies, review applicants, and run research with verified participants. We handle identity, payments, and compliance so both sides can focus on what matters.

Participants
Get paid for your time. Browse studies, see compensation upfront, and apply in seconds.
Every study on Trials Arm shows exactly what it pays, how long it takes, and what’s required before you apply. Once approved, you complete the study and receive payment directly to your bank account. No invoicing, no chasing payments.
Research Labs
Recruit faster with verified participants who are ready to join your study.
Post your study with eligibility criteria and compensation details. We handle participant verification, payment processing, and compliance. You review applications, approve candidates, and run your research. Compensation is released automatically on completion.
What we believe
Compensation should be transparent
Every study lists its compensation, duration, and requirements before you apply. No bait-and-switch, no hidden terms. Participants deserve to know what they’re signing up for.
Verification builds trust
Participants verify their identity. Labs verify their institution. This creates a marketplace where both sides can operate with confidence and reduces fraud for everyone.
Payments shouldn’t be an afterthought
We built payments into the core of the platform. Funds are held in escrow during the study and released automatically on completion. Participants get paid to their bank account — no manual transfers or invoice chasing.
Research should be accessible
Anyone who qualifies should be able to participate in research. We make it easy to find and apply for studies regardless of your background, and we don’t charge participants to use the platform.
