Field testing in 2026
We're building a heavy drone in Finland that fertilises and seeds from the air. The soil stays loose and the crop stays standing.
Unveiling in 2027
Every pass with a heavy machine presses the soil down and flattens a strip of crop. And when the field is too wet, the work just has to wait. A drone does the work from the air and never touches the ground.

soil compaction
Soil packed down by heavy machinery can yield up to 20% less. (Luke)

more grain left standing

less fertiliser
When it lands on the plant and not between the rows, you need less of it. (Journal of Field Robotics)

Our own estimate.
Made in the EU
A drone that does the work, a nest it comes home to, and a flock that brings it jobs. The names are Finnish: Pesä means nest, Parvi means flock. We'll tell you more as field testing goes on.
From planning at the kitchen table to the job in the field, every step is designed around a farmer's working day.
Any implement, spreader or sensor can be attached. We'll license the attachment system to other manufacturers for free, so the drone can do more than we ever planned for it.
Field maps and yield data are worth something. They stay with you, not on someone else's servers on another continent.
Breakdowns always happen at the worst moment. Local service and the right to repair your own machine keep the season on track.
We think Europe should be able to feed itself. That means precision farming, no wasted inputs, and machines whose data stays in European hands.
A drone system that fits everyday farm work. One machine, many tools, and the paperwork taken care of. New technology shouldn't require a new career.
Extreme weather and crises are becoming more common. Security of supply starts in the field.
Farming has a lasting shortage of workers. A machine that does the job itself gives the farmer time back.
Batteries, AI and parts have become cheap enough for a heavy farm drone to finally pay its way.
2026 Now
Building the prototype and putting it to work on real fields with our first pilot farms.
2027
Development wraps up, certification follows, and we unveil the finished system.
2028
Sales open around the EU.

We'll share news from the field tests first, then tell you where and when you can see the drone in person in 2027.
Want to try Tirppa on your own fields? Tell us where you farm and what you grow.
Everything you need travels in one trailer, and PARVI brings you work from farms nearby. By our numbers, a full setup pays for itself in under two years.
Europe's market for farm drones is forecast to grow fast. Would you like to help build a European alternative, or design implements for our drone?
