"Ocean is the new space" - 7 Wild Ideas for the $3 Trillion Dollar Frontier
Will O'Brien's ocean thesis isn't about environmentalism — it's about a multi-trillion dollar resource frontier that the startup ecosystem has almost entirely ignored.
Will O'Brien runs Ulysses, a company operating in the ocean technology space, and he brings the kind of domain specificity to this conversation that makes it stand out from most MFM trend discussions. The ocean is the new space isn't a metaphor — it's a literal argument that the economic opportunity in the ocean is comparable in scale to what space represented to the previous generation of ambitious founders, and that the enabling technologies (autonomous underwater vehicles, satellite-based ocean monitoring, advanced materials) are now at the stage where the Cambrian explosion of applications is beginning.
The ocean surveying segment is where O'Brien gets concrete about what this means in practice. We have better maps of the surface of Mars than we do of the ocean floor. This is not an environmental oversight — it's a commercial gap. Undersea cable networks carry roughly 95% of global internet traffic, and the companies that maintain them have no reliable real-time monitoring of their physical condition. The defense applications of autonomous underwater surveillance are obvious given current geopolitical dynamics. The seafloor contains mineral deposits that dwarf any terrestrial resource discovery in the past century.
The lab-grown seafood discussion is the episode's most consumer-facing idea. The technology for growing fish and shellfish in bioreactors exists; the cost curves are following the same trajectory as plant-based protein; and the addressable market is enormous — global seafood consumption is a multi-hundred-billion dollar market annually. The pirate treasure profit-sharing idea is genuinely absurd in the best way: there are known wreck locations with documented valuable cargo that have never been salvaged because the economics of the salvage operation don't work for any single actor, but might work for a tokenized profit-sharing structure.
O'Brien's closing observation is worth carrying: the founders who will win in ocean technology are those who can operate in an environment where the feedback loops are slow, the data is scarce, and the customer is often a government or military agency rather than a consumer. These are genuine barriers. They're also exactly what makes the category interesting.
Key Ideas
- →The ocean floor is less mapped than the surface of Mars, creating a multi-decade commercial opportunity in basic ocean surveying that has no dominant player and clear government and commercial demand.
- →Undersea cable networks carry 95% of global internet traffic and have almost no real-time physical monitoring infrastructure — a critical infrastructure gap with clear commercial and defense applications.
- →Lab-grown seafood follows the same technology curve as plant-based protein, with a much larger addressable market — the challenge is getting costs below $50/lb for premium species, which is approaching.
- →Marine geo-engineering (seagrass restoration, ocean iron fertilization for carbon sequestration) has potential government and carbon credit revenue that could fund operations waiting for product-market fit.
- →The enabling technologies (autonomous underwater vehicles, satellite monitoring, advanced materials) that make ocean technology commercially viable are at roughly the same maturity level as drone technology in 2012.
Worth Remembering
O'Brien's 'we know less about the ocean floor than the surface of Mars' claim — and the moment Sam and Shaan absorb that this is literally true, not rhetorical exaggeration.
The pirate treasure profit-sharing idea: known wreck locations with documented cargo that have never been salvaged because single-actor economics don't work — described as a possible application for tokenized ownership structures.
The defense drones segment, which O'Brien handles carefully given the sensitivity — but the point about autonomous underwater surveillance becoming militarily essential is hard to argue with given recent geopolitical events.
The 'becoming a monk' tangent at the end of the episode, which starts as a joke and reveals something about O'Brien's philosophy about operating in a category that rewards patience.
