Our Approach

Our Planetary Health strategy is based on the principles of "one-team, one knowledge core." We work together to develop a unified vision of markets and technologies so we can collaboratively build a portfolio of companies that we believe will reveal large market opportunities. We're a visual team, and our growing and constantly evolving maps allow us to contextualize competition and value chain dependency among commercial and development-stage technologies across many markets. We use these maps to present a systems-level view to one another, to companies, and to our partners and collaborators.

Example Maps:

Negative Emissions Technology

Alternative Food Protein

Energy Storage

Non-Ferrous Metal Sorting

Methane Inhibition in Cattle

Nitrogen Fertilizers
