Our story

The patent discovery

Amoéba is an innovative company, created in July 2010 by Fabrice PLASSON.

When the company was founded, its initial objective was to develop a patent from the University of Lyon. This patent is based on a single-celled microscopic organism isolated from a natural environment, the amoeba Willaertia magna C2c Maky, which is able to fight against the proliferation of legionella.

Amoéba then began the development of a new biological biocide for the industrial control of legionella, free amoebae and biofilm.

A successful IPO

In July 2015, Amoéba was listed on the regulated market of Euronext, Paris.

This successful IPO allowed the company to raise €13.2M.

Thanks to this, Amoéba has been able to develop its scientific, industrial and commercial expertise around the amoeba. We are now able to offer technological solutions and products in a wide range of applications.

A diversification of the offer

Amoéba has developed two technologies.

The first one is used for the treatment of water, surfaces and chronic wounds and uses the natural biocidal capacity of the living amoeba Willaertia magna C2c Maky.

The second technology is dedicated to agriculture and more precisely to biocontrol for the treatment of phytopathogenic microorganisms using the lysed (non-living) form of this same amoeba.

Our mission

At the crossroads of environmental protection and public health issues, we are developing a three-fold scientific, industrial and commercial expertise. The company is developing around multiple applications using the amoeba Willaertia magna C2c Maky in the prevention of microbiological risk for water treatment, human wounds and plant protection.

Our commitment

With the growing awareness of the fragility or scarcity of key natural resources such as water, air and food, Amoéba wants to be a major player in the biological revolution in the treatment of these crucial resources, with a global and integrated vision of environmental and health issues. By offering world-class natural solutions that are alternative or complementary to chemical treatments, more respectful of ecosystems, technologically efficient and economically viable, we want to have a concrete impact on the new environmental balances and on tomorrow’s society.


Our values

Make it bold.

We develop disruptive technologies to bring out new alternative solutions, so taking risks is an integral part of our project.

Make it simple.

We always aim for scientific and technological excellence, and we emphasize simplicity and pragmatism in our relationships and operating processes.

Make it happen.

Saying what we are going to do and doing what we said we would do to make our projects a reality, deliver the expected results and be trustworthy over the long term.

Make it fun.

With an ambitious and demanding entrepreneurial project, friendliness, solidarity and efficiency go hand in hand. Having fun at work is a state of mind that everyone must maintain.

Our vision

By 2024, we want to have demonstrated our usefulness and influence by being commercially present in three areas of application: water treatment, agriculture and human health. In this way, we hope to have paved the way for further research and development of alternatives to chemical treatments of our key resources.
