For research teams

Recruitment, handled. So you can focus on the science.

TrialFill takes recruitment off your plate end to end: compliant creative built from your approved materials, campaigns that reach eligible participants, and pre-screened inquiries delivered straight to your screener. Here's exactly how it works, what's included, and what it asks of your team.

What's included

A complete recruitment engagement

Every study includes the full set below. There are no add-on tiers to decode and no surprise line items, you get the whole process for one agreed price.

Eligibility and goal review

We start by understanding your inclusion and exclusion criteria, your enrollment target, and your timeline, so the campaign is aimed correctly from day one.

IRB-ready ad creative

Imagery and copy developed from your approved study materials, written to satisfy both enrollment goals and the language constraints of your institution's review.

Campaign build and launch

Audience targeting, ad setup, and launch on Meta and Google, configured to reach eligible participants in your study's geography and demographic.

Participant routing to your screener

Interested people are sent to your existing screener or intake form, arriving pre-framed and ready for your study staff to take forward.

Weekly optimization

Spend is shifted toward the audiences and creative producing qualified inquiries and away from what isn't, every week the campaign runs.

Clear reporting

Regular updates on the numbers that matter to your study: qualified inquiries, cost per inquiry, and progress toward your enrollment goal.

How it works, step by step

From kickoff to enrolled

Here's what actually happens in each phase, what we need from you, and roughly how long it takes. Timelines vary by study and by your institution's review pace.

1

Criteria and kickoff

We review your eligibility criteria, enrollment goal, timeline, and any recruitment you've already tried. If you have an approved screener or intake form, we look at how participants will flow into it. This is a single conversation, not a drawn-out onboarding.

Typical time1 to 2 days
2

Creative and compliance prep

Using your approved study materials, we develop ad imagery and copy designed to clear both your institution's review and the health-advertising policies of Meta and Google. You see everything before it goes anywhere. When your study requires it, creative is submitted through your IRB or institutional review process.

You provideApproved materials, review sign-off
Typical time3 to 7 days, plus your review
3

Launch

Campaigns go live on the platforms where eligible participants already spend time. Targeting is set to your study's geography and demographic. When a study requires campaigns to run inside your institution's own ad accounts, we work within that setup.

You provideAd account access, if required
Typical time1 to 2 days to go live
4

Inquiries delivered

Interested, eligible people are routed to your screener, arriving already framed for your study so your staff aren't fielding raw clicks. You begin seeing inquiries within days of launch, and we report on quality as they come in.

5

Optimize and scale

Each week, budget moves toward what's producing qualified inquiries and away from what isn't. If enrollment is behind, we can scale spend to accelerate. You receive regular reporting on inquiries, cost per inquiry, and progress toward your goal.

Works with your screener

No new landing page required

A common worry is that digital recruitment means building and approving a whole new intake system. It doesn't. TrialFill routes participants into the screener you already use and your institution already trusts.

If a dedicated landing page would genuinely help a specific campaign, that can be built too, but it's an option, not a requirement.

Platforms and compliance

Built to clear review the first time

Health and clinical advertising carries strict rules on both Meta and Google, and a single non-compliant ad can get an account flagged. TrialFill builds campaigns to those policies from the start, which protects your ad account and keeps your study live.

Creative is developed from your approved materials and prepared to move through your institution's review process, not to fight it. The goal is recruitment that satisfies enrollment targets and compliance requirements at the same time.
