Will O'Brien, founder and CEO of Ulysses, joins John and Chris Sacca for a pint to discuss how underwater autonomous robots are scaling up to solve critical ocean challenges.

They cover the technical history of Guinness (including the math breakthrough that created Student's t-test), why seagrass is an overlooked super-sequester of carbon, and the engineering required to operate robots thousands of meters beneath the surface. Will also breaks down Ulysses' vertical integration strategy, the reality of eco-pragmatism versus "green tape," and what it takes to sell hard tech to defense and offshore energy sectors.
