# Devin Lammers

> 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.
