Citruslabs is the smartest way to find patients

for your clinical trials. We own and operate the

leading health app network that provides you

with pre-screened study candidates.

A New Way of

Patient Recruitment

As featured in

How it works

Candidates use our

health apps

Candidates use our mobile and web apps. We pick

the perfect candidates for your study based on:

demographics, conditions, location, and more.

Candidates enter the Citruslabs platform

We educate patients about clinical trials and

which ones are right for them. Then, they sign 

up for trials that fit their needs and interests.

Researchers connect

with candidates

Your candidate data is consolidated into our easy-to-use 

dashboard that makes contacting, scheduling, organizing,

and pre-screening patients for your clinical trial effortless.

Making a difference is in our DNA.

Pre-screened patients are just a few clicks away. Citruslabs saves you time by identifying patients who may qualify for a study before they’re sent to you.

We're proud of the things we achieved together with our great partners.

We are always patient first.

3 million  patients in our database

150+  clinical trials served

20+  indications covered

Education and Advocacy

Unlike other patient recruitment companies, we educate our patients on research and advocate for clinical trials - making our “no longer interested” and “can’t be contacted” rates extremely low. Our patients are motivated and actively interested in enrolling in your clinical trial.

Top Health Areas

Our patient network draws from the leading app for baby boomers and the #1 health app across 17 countries. We’re also top referrers in the therapeutic areas of cardiovascular/metabolic, CNS, dermatology, gastroenterology, infectious diseases, oncology, and many more.

We’ve helped hundreds of researchers successfully complete clinical trial recruitment, including:

Karen McCrea

California Research Foundation

San Diego, CA

We are currently working on a clinical trial and the sponsor chose Citruslabs to assist us with finding suitable candidates. Candidates were listed on their easy-to-use website where updates were quick and convenient to make. Citruslabs was very responsive to questions and very helpful in the referral process.

Anthony Liu

Research Coordinator

University of Washington, Seattle, WA

We worked with Citruslabs on a study where we recruited healthy male volunteers. The study was a little difficult to recruit for but within the first 10 referrals they sent over we were able to get a randomized patient. Citruslabs was quick to respond to any of my inquiries and always took quick action to fix any issues.

Annie Hanks

Wasatch Clinical Trials

Salt Lake City, UT

We really enjoyed working with Citruslabs on a number of different Phase ll & Phase lll clinical studies. Their MindMate app has already referred us well over 100 pre-screened local study candidates in real-time. Having their own patient population means we can target specific patients, which helps us to boost recruitment also for the tricker studies we are running.



Citruslabs collects demographic, medical and behavioral data.

Users get educated about clinical trials & have to go through a

comprehensive opt-in process to be considered for a clinical trial.

86% of clinical trials don’t

meet patient targets

Traditional advertising is expensive & inefficient
