Drop the duds. Surface the gems. Hit your timeline.

Exafi predicts which sites will underperform before you commit activation budget and start-up resources, from real-world signals, not self-reported feasibility surveys.

Sites get activated based on

Reputation & Experience and Biased self-reported data

You don't find out they were wrong until the budget is spent and participants don't show up.

How it works

Real-world signals ranked sites, before you activate.

Step 01

Share your protocol

Share a protocol summary and candidate-site list. No patient-level data, integration, or platform migration. Protocol content is used only for your analysis, not to train shared models.

Step 02

exafi scores every site

Our AI-powered engine scores each site on proprietary signals, dropping the duds and surfacing the unexpected gems.

Patient density Investigator track record Trial saturation Compliance history

Step 03

Activate the winners

Take a ranked, explained shortlist into your selection meeting, and commit only to the sites that will actually enroll.

Every activation makes the agents smarter.

The pilot

Run it on a real activation decision.

Send us a trial and a candidate site list. We run it through exafi and send back a scored, ranked shortlist, with the reasons behind every site, so you activate the ones that will actually enroll.

  • No platform contract. A scoped pilot on one real activation, not a year-long commitment.
  • Every site scored 0 to 100, with plain-English reasons you can defend internally.
  • A ranked shortlist you can use this cycle, delivered fast.

Please don't submit confidential files here. We'll arrange secure transfer after an NDA.
