Who You'll Work With

Founder-run. No hand-offs.

TrialFlow is run by Haikal Shariff, who builds and manages every campaign personally — strategy, creative, targeting, and reporting — and works directly with your coordinators from day one.

TrialFlow Recruitment is a clinical trial patient recruitment agency built for research sites struggling with slow study enrollment. Instead of call centers or expensive patient databases, we use targeted Meta (Facebook and Instagram) advertising to reach eligible patients near your site — from the Dallas–Fort Worth area, where we've recruited for COPD, MASH, obesity, heart-failure, and MASLD trials, to research sites anywhere in the United States. Every engagement includes ad creative, IRB-ready landing pages, pre-screening lead forms, and weekly performance reporting, so your coordinators spend their time enrolling patients instead of searching for them.
