The Ocean Company just closed a $46 million round led by a16z American Dynamism. Co-founder and President Will O'Brien argues this is the opening move in treating the ocean not as a destination but as a permanent economic zone, and eventually a place where humans actually live.

The core argument, co-written with Not Boring's Packy McCormick, is that humanity has always treated the ocean as a visiting relationship: exploit it, explore it, leave. O'Brien wants to build the infrastructure that ends that pattern. The essay traces a history of the ocean economy most readers will not have encountered, grounding a large ambition in specific precedents and physical constraints.
