About Us
Building the Future of Sustainable Nutrition
I believe microalgae will become one of the world’s most important sustainable resources. At Viride, we’re turning this vision into scalable technology that benefits both people and the planet. My role is to bridge science, engineering, and business to create real-world impact. Every challenge brings us one step closer to a more resilient food system. I’m proud to build a company where innovation serves sustainability.

Our logo: The colibri represents water & life
“Once upon a time…” there was a rocky island in the middle of the ocean. There was no grass, no life just rocks. Then a hummingbird showed up. Every day, it brought a few drops of water. Over time, the island turned green. Moss and grass grew, small animals arrived, and life flourished.
This is what algae can do in our world today: bring water, life, and nutrients to dry and remote places and help build ecosystems around them. Algae are not only a source of food and feed; they can also enrich the soil and support plant growth.
Our Journey
From nature to innovation.
The Beginning
In 2020, we began exploring ideas around microalgae and their potential. In 2021, that vision took shape with the creation of our company in Germany, marking the beginning of our journey.
Exploring Microalgae
In 2022, we started Viride Maroc and began turning our vision into reality. In 2022–2023, we built our first cultivation ponds at Tamaya, taking our first steps into microalgae production.
Innovation Takes Shape
In 2024, we took a major step forward with large-scale equipment, improving our production capacity, efficiency, and cultivation processes.
Alga Naturals
In 2025, we focused on optimizing our production and refining our processes. In 2026, we founded Alga Naturals, opening a new chapter focused on bringing the potential of microalgae into everyday products.
The Future
Our journey continues with a clear ambition: more flavors, more production, and more applications bringing the benefits of microalgae to more people while creating a healthier and more sustainable future for everyone.
