**How this map is made.** Every startup here has raised money in rounds we track, and is based in United States. It joins the map when its sectors, read from its rounds, or the opening of its own description say it works in ocean tech, and goes to the first segment whose words it carries. Each segment shows its best-funded first. Rebuilt nightly; updated 15 November 2026.
