Terradepth
Terradepth is an Austin-area ocean-data and subsea-intelligence company founded in 2018 by former U.S. Navy SEALs Joe Wolfel and Judson Kauffman. It pairs autonomous underwater vehicles that collect seabed data with Absolute Ocean, a cloud-native, government-grade platform for storing, visualizing, sharing and analyzing that data. Marketed as Ocean-Data-as-a-Service (ODaaS), Terradepth serves defense, offshore energy and maritime customers who need to map, understand and protect the roughly three-quarters of the planet that lies underwater.
Garth Sheldon-Coulson
Garth Sheldon-Coulson is the co-founder and CEO of Panthalassa, a Portland, Oregon company building free-floating, wave-powered nodes that generate clean electricity in the open ocean and pair it with onsite AI computing. A Harvard-trained lawyer with an MIT master's and a Bridgewater investing background, he pivoted from finance to spend nearly a decade inventing marine energy hardware. In May 2026 Panthalassa raised a $140M Series B led by Peter Thiel, pushing its valuation near $1 billion, on a bet that the open ocean is one of only three energy sources on Earth with tens of terawatts of untapped capacity.
