Devin Lammers is the CEO of TerraClear, the Issaquah, Washington agtech company building AI and robotics to pull rocks out of farm fields - and, increasingly, to scout entire fields for weeds, crop health, and more. He took the helm in August 2024 after seven years at Farmers Business Network, where he founded FBN Financial and Gradable and served as CRO/COO and interim CEO across a network of 50,000-plus members. A multi-generational South Dakota farm-and-ranch kid with a Dartmouth degree and an MIT Sloan MBA, he frames agtech as 'the intersection of technology meeting the physical world' and is steering TerraClear from a single hated chore toward a full-field autonomous intelligence platform.
TerraClear builds AI-powered machines that take one of farming's oldest, most miserable chores - picking rocks out of fields - and make it fast, precise, and increasingly autonomous. Founded in 2017 by serial entrepreneur and farm-raised Brent Frei, the Issaquah, Washington company pairs drone-based mapping, machine vision, and a robotic rock picker that clears hundreds of rocks an hour. In 2026 it launched TerraScout, a fully autonomous field-scouting robot that scans up to 1,000 acres a day for rocks, weeds, and more, turning images into real-time prescriptions for existing farm crews and equipment.
