In 1984, OPI started with a dream to add value to the family farm. Owner, Dave Crompton, and his family constructed the first cable on their kitchen table to fill a gap in their winter wheat trials. They needed assurance that the grain quality was on par. They drew from the old English adage, “an ounce of prevention is worth a pound of cure.” Thus the acronym OPI was born: Ounce of Prevention Insurance. And from humble beginnings came a proven technology.

Decades later, with the support of valued partners, the mission ofd perfecting the art of in-bin grain management continues. OPI empowers over 25,000 customers in over 75 countries to ensure every grain gets to market. Inside the walls, it employs talented visionaries that unite technologies latest innovations and agriculture.

Changing the Story

Adding value to the family farm and contributing to the sustainability of the global population is of vital importance. Whether on a farm or within the commercial market, the state of stored grain serves as a barometer for overall performance.

Maybe you have or know someone who has lost a bin to spoilage. Worse yet, maybe you’ve lost a friend or family member who entered the bin to clean it out. Or you are delivering grain too soon or too dry and losing valuable earnings. OPI aims to eliminate losses with technology.
