Sound familiar?

This is how most charterers still find tonnage.

01

Same cargo, four WhatsApps.

Slightly different wording each time. Four conversations to manage — none of them structured.

02

KYC pack. Again.

Passports, trade registration, bank refs. Every new broker, every fixture — the same docs in a new email chain.

03

Where does it stand?

You sent it two days ago. No reply. Reviewed? Forwarded? Lost? You just don't know.

Search once. Inquire once. Track everything.

Live tonnage, one structured inquiry, KYC reused, and a clear status on every deal — from first contact to fixed.
