Tidal vs Sedna

Sedna and Tidal solve different parts of maritime procurement. Here is how they compare, on the facts.

★ 5.0 on Clutch, 10 reviews Live in about 1 week Quote in under 30 minutes IMPA & ISSA 90%+ first pass

Sedna is an email and communication intelligence platform for shipping and commodity trading. It centralises shared team inboxes, adds structure and automation to high-volume email, and helps teams act on messages faster. Tidal overlaps on one word, email, but does a different job: it reads procurement email RFQs specifically and turns them into accurate, margin-protected quotes, matching each line to IMPA and ISSA codes.

Put simply, Sedna helps a team manage and route all of its email; Tidal takes a procurement RFQ out of the inbox and produces the quote. They are complementary. A supplier can run Sedna for communications and Tidal for the RFQ-to-quote workflow.

Where each one fits

Choose Sedna when the problem is email itself at scale: shared inboxes, routing, tagging and automating a high volume of messages across chartering, operations and trading. That is what it is built for.

Choose Tidal when the specific job is procurement RFQs: turning an email enquiry of hundreds of line items into an IMPA and ISSA-coded, margin-protected quote in under 30 minutes. Tidal is purpose-built for that one step and goes live in about a week.

Where Tidal is less mature

Being honest: Sedna is a mature communications platform that handles far more of a team's email than Tidal, which only touches procurement RFQs. Tidal is a newer, smaller company with SOC 2 Type II in progress. If you need to run all of your shipping email through one intelligent layer, Sedna is the relevant tool, and Tidal can sit alongside it for quoting.
