Portcast

Portcast — Container-level shipment event stream normalised across 220+ ocean carriers: for each container/booking/B/L, a timestamped milestone history (booking, gate-in, loaded, departed, transhipment, arrival, gate-out, delivery), vessel schedule and real-time AIS position, plus a predictive ETA/ETD per leg. The high-value latent asset is the correction history — every ETA the platform issued versus what actually happened, accumulated across carriers, routes and disruption events. That forecast-versus-outcome pairing is the byproduct and is not something a carrier publishes.. Small but well…

Portcast offers (Alternative, Supply Chain) — Coverage stated as 220+ ocean carriers. Global containerised trade runs to roughly 800M-900M TEU a year across the carriers covered, so with each container generating 5-10 milestone events the normalised event corpus is plausibly O(10^9) events cumulatively — order-of-magnitude only; the vendor publishes no container, shipment or event counts, so this must be sized against their logs in diligence.

Retail and CMO supply-chain planning (arrival-date confidence driving inventory placement and lost-sales avoidance); carrier selection on realised reliability rather than published schedules; freight-forwarder exception management; and for financial buyers, high-frequency nowcasting of port congestion, import volumes and regional demand from arrival and dwell patterns — including US-bound Southeast Asia flows, which this specific coverage page targets. Also training data for ETA-prediction models, which is scarce outside the largest carriers.

The data is with 6 years of history.

Coverage spans US, APAC, UK; Application Software, Marine Transportation; alternative, supply_chain; equities.
