Our Vertical Farming is based on a circular economy. With the right people, technology & know-how we actively shape the future of food, whether in deserts, cities, remote islands, or in outer space.

"Our mission is to feed the world sustainably and contribute to your health."

Our story

Creating impact to change the industry as we know it today.

YASAI, established in 2020, builds and manages Vertical Farms. We create circular food production systems in cities and regions where agricultural resources, such as freshwater and fertile arable land, are scarce.

Our model boosts biodiversity by combining food production with resource-saving technologies and eliminating pesticide use. By focusing on locality and premium quality, YASAI replaces food imports and lowers production costs across the supply chain.
