Mariner Logistics, a Coppell, Texas-based asset-backed 4PL, has appointed Justin Turner as its new CEO. Turner, a former Coyote Logistics early employee and Flock Freight chief revenue officer, brings experience scaling brokerages and freight tech companies. The company operates over 300 owned tractors, 800 trailers, and 1 million square feet of warehouse space, serving manufacturing, aerospace, defense, and data center clients. Turner highlighted Mariner's Sentinel Protocol, a multi-source carrier and driver verification standard built for high-value freight security. The company also uses an AI layer called Vibe Engine for automated spot procurement and carrier matching. The article notes that the Supreme Court's May 14 ruling in Montgomery v. Caribe Transport II has reshaped broker liability, impacting carrier vetting practices.
