BlueCargo

Here is a fact about global trade that sounds made up but isn't: a shipping container can cross an entire ocean for a fairly predictable price, and then lose that predictability entirely in the last thirty miles. The box arrives at a US port terminal, and if it sits there a day too long, a fee starts. If the truck keeps the chassis too long, another fee starts. If the empty isn't returned on schedule, a third fee starts. These are called demurrage, detention, and per diem, and collectively they can turn a $2,000 move into a $7,000 one without anyone quite deciding that it should.

The strange part is not that these fees exist. The strange part is that, for years, almost nobody could tell you with confidence whether a given charge was correct. Terminals ran on their own schedules, appointment systems, and closures. Invoices arrived weeks later as PDFs. The data needed to contest a charge lived in one place; the charge lived in another; and the person paying it lived in a third. So most companies did the rational thing under conditions of confusion, which is to say they paid and moved on.

BlueCargo is a company that decided not to move on. Its entire proposition is that these fees are legible if you gather enough data, and that a meaningful share of them are wrong - and therefore disputable. That is a deceptively boring thing to build a startup around, and it is also, as it turns out, worth a lot of money. The company says it has helped customers recover more than $175 million in fees. One customer, the freight brokerage Forrest Logistics, is reported to have saved over $5 million in a single year.

The founders, Alexandra Griffon and Laura Theveniau, are two French engineers who met at UC Berkeley in 2018 while studying data science and AI, and then wandered down to the nearby Port of Oakland, where they ended up working on Navis - the terminal operating system that runs the yards. This is a useful biographical detail, because it means they did not discover the demurrage problem from the outside as a market opportunity. They discovered it from the inside, standing next to the machines that generate the very data their product now audits.

The timing helped. When the pandemic jammed US ports in 2020 and 2021, the previously invisible cost of drayage became a boardroom problem overnight. Containers stacked up, fees ballooned, and suddenly every importer wanted to know exactly where their box was and whether the charges were fair. BlueCargo had been building for precisely that question since 2018. It is a familiar pattern: the best time to understand a boring problem is several years before it becomes an emergency.

What BlueCargo built is not a single app but a stack. It integrates data from hundreds of sources across North America's busiest container ports and stitches together a container-level view of what is happening: where the box is, what the terminal is doing, which appointment windows exist, and what fees are accruing. On top of that data sits the actual product - tools to schedule pickups and returns, track container milestones, and audit invoices line by line against the terminal record. When the math doesn't add up, the platform files the dispute.

● The founders met working on Navis, the terminal operating system that runs the yards. Their product now audits the very data those systems produce.

● Both founders are French, studied AI at Berkeley, and built a company about the plumbing of American shipping.

● BlueCargo deliberately skipped the glamorous “ocean” part of freight to obsess over the 30 messy miles from port to first warehouse.

● The entire business rests on three fees - demurrage, detention, per diem - that most people outside logistics have never heard of.
