HARVESTERS FOR GREEN ASPARAGUS

We are revolutionizing the harvesting of ground-level crops through intelligent robotics.

TOO FEW
HARVEST WORKERS.

German agriculture is lacking thousands of harvest workers. The work is complex and strenuous. In addition, the wage costs are constantly increasing. For some special crops, automation was previously out of the question due to the precision required. We are working to change that.

OUR CONCEPT

We combine AI with precise actuators and build the green asparagus harvester of the future.

CARRIER VEHICLE

HARVEST MODULE

Our focus lies here!

Works if its an old, new or even autonomous tractor

PRECISE ACTUATORS.

Image recognition algorithms and precision mechanics enable us to cut with millimeter accuracy.

MODULES UNDER DEVELOPMENT

Our goal is to develop the following modules, which will later be deployed in the field in combination with the carrier vehicle. 

FLEXIBLE & SCALABLE

We rely on a solution that is modular and compatible, allowing farmers to use their existing infrastructure to smoothly transition into the era of precision farming. We offer everyone a reliable and more cost-effective alternative.

WHO WE ARE.

We are a young start-up, founded by students from the Karlsruhe Institute of Technology and the University of Hohenheim. Driven by a pioneering spirit and passion for agricultural technology, we are revolutionizing agriculture. 

HOW IT ALL BEGAN...

We started by automating the saffron harvest, which is the most labor-intensive harvest in the world. Now we are using the same innovative technologies to automate the green asparagus harvest. This will make efficient and sustainable cultivation possible in Germany in the long term. We will also pursue this approach for other specialty crops, such as broccoli, and many more starting in 2028.

Our second time at ExpoSE in Karlsruhe, this time with our first complete machine. We experienced a clearly positive response from numerous interested farmers, far exceeding the number of visitors and the level of interest shown at our last visit. The machine pictured here will be one of two that will be deployed in our farmers' fields during our pilot phase in 2026.

EU funding logo

With funding from the NBank under the HTI program (ERDF/STEP)—and in collaboration with the Seedhouse Accelerator—Prefiro is developing the first selective, modular green asparagus harvesting machine. The goal is to offer farmers an efficient, selective, and sustainable alternative to manual harvesting through the use of AI-driven image recognition and custom-developed precision robotics. This funding enables us to advance our modular harvesting technology to commercial maturity and, for the first time, deploy it in the field as a practical, ready-to-use solution.
