Progressive Farmer: Poised for flight, Iowa startup hopes to provide efficiencies and options with amped up drone sprayers

The world headquarters of Rantizo screams tech startup. The small company that’s pushing the edge on autonomous drone spraying systems feels out of place in downtown Iowa City, wedged between a flower shop and a store hawking University of Iowa T-shirts.
