If you lead clinical trial recruitment and enrollment, you’re well aware of the boom in the aggregator market in recent years. A 2025 CISCRP survey of 12,000+ patients shows that low awareness is still a top reason patients don’t participate in trials. New platforms keep launching, each with a promise of solving this problem.
Aggregators aren’t wrong to chase that problem, but awareness is only the first hurdle. Aggregators, by definition, include ALL trials, including trials that aim to examine if cold showers will reduce your sick days. Once a patient weeds through the more fringe experimental interventions and discovers a relevant trial, they still need to:
An aggregator listing can help someone notice your study. It can’t do much to get them to enroll.
This is where owning your clinical trial recruitment technology can help. One tool in particular that bridges the gap is a sponsor-owned trial finder website. Let’s talk about it.
Search any public forum where patients are looking for trial opportunities, and most responses recommend aggregators and registries like ClinicalTrials.gov. These sites are broad, searchable, and arguably the most comprehensive.
But breadth comes at a cost. These sites were built as registries to list every trial—and not for enrollment, let alone to promote any one trial well. Patients get lost on pages dense with clinical and regulatory language, eligibility criteria written for regulators rather than patients, and far too much of the information they don’t need (yet not enough of the information they do need).
This experience is confusing—and even discouraging—for patients trying to figure out if a study is right for them. When people feel lost, they just give up.
Trust is an issue, too. On these sites, the sponsor organization is reduced to a name and a logo in a sea of jargon. There’s no room to shape the messaging, build credibility, or emphasize patient-centric values that motivate patients to take the next step. CISCRP’s 2025 data found that only 18% of patients say they trust pharma “a lot” when it comes to clinical research, and these listings aren’t helping to improve that.
But in that same research, 49% of patients said they’d trust a pharma company more if they knew it actively worked with patients, caregivers, and communities to make participation easier. Thirty-nine percent would have higher trust if information were shared in language they could actually understand.
You won’t find evidence of either on an aggregate site or federal registry. But a sponsor can address both with its own trial finder website.
A well-built trial finder website does what aggregators can’t.

Here’s how sponsors can turn a trial website into a real recruitment-boosting asset.
Recruitment delays are one of the most expensive and unpredictable variables in a trial timeline. A custom, sponsor-owned trial finder site is a true enrollment lever, not just a marketing nice-to-have. Done correctly, it converts more patients, keeps disqualified participants engaged and interested, frees up funding to invest in outreach and gives your team visibility an aggregator listing simply doesn't provide.
