For the second consecutive year, Iowa will be represented in the final four of the American Farm Bureau Federation Rural Entrepreneurship Challenge — this time by two companies: AccuGrain LLC, based in Rose Hill, and AgriSync Inc., based in Dallas Center. The organization announced the top 10 finalists Wednesday in Washington, D.C., and the final four that will compete during the next phase of the challenge. AccuGrain, an agricultural technology entry, uses X-ray technology to inventory flowing grain in real time. Iowa’s second representative, AgriSync, uses a mobile customer support platform for farmers and is also an agricultural technology entry. The final four teams, chosen from 165 applicants nationwide, were each awarded $15,000. The four finalists will pitch their business ideas to a team of judges at AFBF’s 97th Annual Convention and IDEAg Trade Show in Orlando, Fla., in January for chances to win a total of $40,000 in prize money to implement their ideas.
