Brent Frei is learning how to pick rocks with a robot as he continues to work on his new company, TerraClear. Based on the interest generated by a new funding round, Frei may have picked another winner.

TerraClear raised $5.5 million in a friends and family round that Frei said was intended to raise $1 million or $2 million.

Frei, the co-founder of Smartsheet — the Bellevue, Wash.-based company that went public in April — has been working on the Idaho farm where he grew up, developing a machine that he hopes will someday remove troublesome rocks from the land used to grow crops. He shed light on TerraClear this spring, and Thursday told GeekWire what the new funds will do.

“It’s capital to do all of our prototyping and build out the team and go bigger faster,” Frei said. “So far a lot of the design work we’ve been doing and the early prototyping, both of scale models and of life-size models, is pretty encouraging. It’s a lot of fun. It made a lot of sense that we raised more than we were originally intending to because it’ll definitely be necessary as we get closer to a production product.”
