Adrian Ferrero is the Co-Founder and CEO of Biome Makers, where for eleven years he has used DNA sequencing to read the communities of microbes living in soil and turn them into a functional picture of soil health. An economist by training who calls himself an innovator, Adrian sold an earlier DNA diagnostics company with his childhood friend Alberto Acedo, then reinvested everything to bring the personalized medicine concept into agriculture.

In this episode, Adrian explains how Biome Makers profiles the bacteria and fungi in soil samples, why organic and conventional apples carry very different microbial loads, and how thinking about soil at a functional level rather than a taxonomic one let the company compare farms across 56 countries. He breaks down nutrient use efficiency, why nitrous oxide is hundreds of times more potent than carbon dioxide, and how better soil data helps farmers use less fertilizer while polluting less.

The conversation also goes deep on the human side of building a company. Adrian shares why growing the team from two people to 55 was his hardest challenge, how he leads a remote and multicultural company across the US, Europe, Asia, and Latin America, and why he tries to keep business fun even in serious negotiations. He closes with a reminder not to underestimate our impact on the soil, and advice to build your own expectations and be brave enough to try.
