Our Founder
Sergio Dinaro, MBA
Founder & CEO
Retired federal agent with extensive experience in investigative interviewing, statement analysis, and deception detection. Drawing on decades of field work, Sergio created TRACER to bring scientific rigor and consistency to the assessment of verbal and written statements — making advanced linguistic analysis accessible to every investigator.
Our Mission
TRACER exists to democratize deception-likelihood analysis. We believe every investigator — from a solo private detective to a federal task force — should have access to the same caliber of linguistic analysis. By automating the repeatable, analytical work, TRACER frees professionals to focus on what matters most: judgment, context, and the pursuit of truth.
