The 4PL that doesn't just coordinate your
freight: we're accountable for it.

Most 4PLs Manage Your Freight.
We're Responsible for It.

There's a difference between a 4PL that coordinates carriers and one that owns them. Between a platform that tracks your freight and one that guards it. Between a provider that manages exceptions and one that's accountable for outcomes.

Mariner was built on the second half of each of those sentences.

We are the managed transportation partner with owned assets on the road, proprietary technology in the control tower, and a cargo security platform that treats every load like it matters — because for our customers, it does.
Fewer customers. Higher standards. That's the Mariner model.

Iron on the Road

300+ company-owned trucks. When your freight moves on Mariner assets, there's no broker, no middleman, no margin stack. Just a truck we own and a driver we trained.

One Pane of Glass

Mariner Live puts every mode TL, LTL, air, ocean, rail, warehousing into a single real-time platform. No emails. No blind spots. One source of truth.

Security by Design

300+ company-owned trucks. When your freight moves on Mariner assets, there's no broker, no middleman, no margin stack. Just a truck we own and a driver we trained.

The Mariner Model

PILLAR 01
THE ASSET BACKBONE

Assets. Power Units.

300+ tractors. 800+ trailers. When your freight rides on our iron, you're not paying for a broker's relationship with a carrier. You're paying for the truck. That's a different cost structure, a different accountability structure, and a different risk profile — permanently.
PILLAR 02
THE TECHNOLOGY LAYER

Mariner Live

Built by us. For freight like yours. Every mode. Every milestone. Every communication. Inside one platform, behind one login, on one authenticated record. We built our own TMS because off-the-shelf wasn't built for the standards our customers require.
PILLAR 03
THE SECURITY LAYER

Sentinel AI

Cargo security as infrastructure. 26-point carrier qualification. 100-point lane threat scoring. Biometric driver verification at every pickup. CargoNet and FreightWatch integrated in real time. When your freight can't be compromised, neither can your carrier network.

Company-owned power units

1.5M+
