Yield you can measure.

Carbon removal

Our proprietary mineral conversion platform runs on the world's spare kiln capacity; we are starting with turning cheap, abundant silicate rocks into carbon-negative fertilizer

Demand is rising as growing conditions become more challenging.

The world has to feed billions more people this century while the ground it farms on grows hotter, drier, and more depleted. Two curves bending the wrong way at the same time.

of the world's population could be affected by drought by 2050

Resilience today for a brighter tomorrow

Our plant available silicon makes crops tougher by thickening the cell walls and increasing nutrient use efficiency

A simple process turns inert rock into a fast-weathering fertilizer that feeds crops and removes CO2

Step 01

Inert Feedstock

Cheap, abundant silicates plus limestone.

Step 02

Activation

Proprietary thermal ion exchange, run in existing cement kilns — developed at Stanford.

Step 03

Activated Product

Valorized minerals ready to release nutrients while removing CO₂.

Step 04

Field Deployment

Drop-in with existing farm equipment — delivers benefits at agronomic application rates while reducing conventional fertilizer use.

Revenue today,
not a decade from now.

Mafix activates abundant silicate rock into climate-smart fertilizers that improve yields while removing CO₂ , a process known as enhanced rock weathering (ERW). Because it's drop-in, we scale on existing spare kiln capacity, with no costly first-of-a-kind facility to build. Mafix generates revenue in the first growing season.
