Ag tech startup wins top prize as UW’s Dempsey competition awards $92,500 to all winners

The grand winner of the University of Washington’s 29th annual Dempsey Startup Competition was BioBead, a startup founded by a UW team with an ag tech solution to improve soil health and crop production.
The company won $25,000 from BECU and the $2,500 Voyager Capital Best Business to Business Idea Prize.
A record 186 entrants entered the competition, whittled down to 16 who competed in front of the judges in ridiculous locations. The winners took home a share of $92,500 in prize money.
The event is open to student entrepreneurs from across Washington, Oregon, Idaho, Alaska and British Columbia. Entrants range from very early stage startups with a prototype to teams with small working products or technologies ready for commercial production.
The competition lasts seven weeks, during which teams refine their strategies – hiring business students to strengthen go-to-market plans, for example. The judges this year recognized that AI is helping teams to design complex technologies.
The awards were announced at a ceremony in Seattle on May 21.
Grand prize recipient BioBead makes small, biodegradable pellets that include bacteria and fungi that have coexisted in the soil for 400 million years, helping plants absorb essential nutrients including nitrogen and phosphorus.
“Humans seem to be disconnected from everything under our feet because we don’t see it,” said Korena Mafune, BioBead co-founder and UW research scientist. But those creatures are what allow above-ground plants to thrive, he added.
BioBead’s co-founders are Renee Davis, who is completing her doctorate at the UW, and Mari Winkler, a UW professor of civil and environmental engineering. Jared Espinosa, a recent MBA graduate from UW’s Foster School of Business, joined the competition team.
The startup has been working with farmers who grow lettuce, tomatoes, corn and wheat to test the benefits of soil treatment. Initial results show higher yields while reducing the need for expensive fertilizers.
Mafune last month also won a $275,000 grant from the Washington Research Foundation to support the commercialization of the technology.
