Innovation begins with discovery.

We go to the world's harshest places to find what nature has already perfected, bringing it back to protect skin, soil and the planet.

A story of discovery, innovation, and protection.

In the depth of California desert we found rare thermophilic microbes that had been protecting life in the harshest conditions for millions of years.

Discovery

01

Where others saw desert, we saw opportunity.

Nature had already solved the problems humanity faces, it just needed to be discovered. A rare heat loving microbe was discovered in the deserts of California. For millions of years, this organism has sustained surrounding life under extreme environmental conditions.

Innovation

We give nature's innovation a voice.

We leverage the power of the nature's microbe to produce the fermentation platform and deliver a product range humanity and the environment can benefit from.

Protection

03

Protection is in our DNA.

Our microbes evolved to protect themselves and the ecosystems, including plants and other microbial communities, around it. We put that same instinct to work for skin, soil and the planet.

Everyone can be part of the solution.

We work with nature and communities to protect the ecosystems we all depend on.

Close-up of soil with fine roots and microbial threads

01

Grow more, with less.

Stronger roots and healthier crops from the same ground. Plants stay resilient through drought, growing well on as little as half the water. More resilient crops mean more dependable harvests in a harsher climate.

03

Protect human skin.

A natural melanin that shields skin from UV, visible and infrared light.

02

Reduce atmospheric methane.

Every application returns methane-eating microbes to the soil, pulling a greenhouse gas out of the air.

04

Protect marine life.

A sustainable melanin that replaces sourcing from cuttlefish and other sea animals.
