Our Story

Petiole is an award-winning agtech company that was started when co-founders Andrii and Maryna decided to help their friend Vyacheslav, who worked as an ecologist at the Institute of Evolutionary Ecology in Ukraine. Vyacheslav struggled with measuring the area of poplar leaves, and Andrii and Maryna realized that existing solutions like leaf area meters or software like ImageJ were not effective, affordable, or accurate. They founded Petiole to address these problems and provide a better solution for collecting leaf area data.

Anticipating a future with high-throughput plant phenotyping of structural and functional plant traits, the they designed and developed a mobile application called Petiole Pro. This app is built with sustainable agriculture in mind and includes the world’s most accurate digital leaf area meter and other modules based on computer vision, machine learning, and artificial intelligence. These modules follow a scalable approach and are available 24/7.

Here at Petiole, we are motivated to empower global communities by increasing access to innovative agtech solutions for our customers around the world.
