Meriz

CEO & Co-Founder — Andes

He quit a lucrative career in wealth management after the birth of his child, moved from Santiago to California, and built a company around a counterintuitive bet: that the smallest organisms on Earth could solve one of its largest problems.

Microbes, Millions, and a Career Nobody Plans For

It takes a certain kind of contrarianism to look at a trillion-dollar chemical agriculture industry and conclude that the answer is smaller. Much smaller. Gonzalo Fuenzalida-Meriz built Andes on the premise that beneficial soil microorganisms - organisms that have been fixing nitrogen and weathering minerals for billions of years - can replace synthetic inputs, generate measurable carbon removal, and do both simultaneously at farm scale.

The path there was indirect. Gonzalo studied business administration, finance, and economics at the Pontificia Universidad Católica de Chile. He joined Banchile Inversiones as a Senior Wealth Manager in 2010, managing portfolios for high-net-worth clients. By most external metrics, it was a successful career. By his own account, it was a miserable one.

"I was in a very well paid [career], but I honestly was a very unhappy person. My Sundays are beautiful now. I love what I do."

- Gonzalo Fuenzalida-Meriz

The inflection point was personal, not professional. The birth of his child - a moment he describes as seeing a miracle - triggered an instant reordering of priorities. The things he thought mattered stopped mattering. He left banking.

From Santiago to Alameda: The Long Way Around

His first move into biotech was in 2013, when he founded Ango - Austral Biologicals in Chile, followed by co-founding Epiphany in 2017. Neither was Andes. Both were stepping stones into the science and business of biological solutions, building instincts that wouldn't fit in an MBA curriculum.

Andes came in 2018. The company landed in Alameda, California - a former Navy base turned innovation district across the bay from San Francisco - and Gonzalo arrived with a conviction: that microbial technology was ready for something bigger than niche applications. The question was how to make it commercially legible at agricultural scale, and how to prove the carbon removal science rigorously enough to satisfy institutional buyers.

The former required working directly with major crop input distributors - Wilbur-Ellis, Corteva, Nutrien. The latter required something that didn't exist yet.

Building the Methodology That Didn't Exist

Most carbon removal projects work from pre-existing carbon accounting frameworks. Gonzalo's team had a problem: the specific mechanism Andes uses - microbial weathering of soil silicate minerals, which converts atmospheric CO2 into stable inorganic carbon that can persist for thousands of years - had no recognized methodology for quantification or verification.

So they built one. In partnership with Gold Standard and measurement firm EcoEngineers, and with scientific review from experts in geochemistry, soil science, environmental microbiology, and agriculture, Andes developed the world's first Microbial Carbon Mineralization (MCM) Methodology. Published in July 2023. Validated against ISO 14064 international standards in September 2023.

The methodology covers quantification, monitoring, reporting, and verification for carbon projects using microbial seed treatments. It makes Andes' carbon credits legible to institutional buyers and corporate sustainability programs in a way that didn't exist before. Research partners from Lawrence Livermore National Laboratory, Rice University, and the University of Colorado Boulder provided independent scientific validation for the underlying mechanisms.

"Transparency and rigor in carbon removal is of utmost importance."

- Gonzalo Fuenzalida-Meriz, Carbon Herald

The Business Model Built Around the Farmer

Carbon credit schemes have a reputation problem in agriculture. Farmers are asked to change practices, absorb risk, fill out paperwork, and receive payment years later for outcomes they can't verify. Gonzalo structured Andes specifically to invert this dynamic.

Andes' Microprime platform - microbial seed coatings applied to corn, soybean, canola, and wheat seeds - is provided to farmers at zero cost. The microbes include nitrogen-fixing strains that demonstrably reduce synthetic fertilizer requirements, and mineral-weathering strains that convert CO2 into stable soil inorganic carbon. The farmer pays nothing and gains something concrete: yield increases of five to six bushels per acre and documented net income improvements of 20-30%.

The carbon credits generated belong to Andes, who sells them to corporate buyers managing Scope 3 emissions and sustainability commitments. The entire commercial structure is designed so the farmer's incentive and the climate's incentive point in the same direction.

"When we started the carbon program at Andes, we wanted to make it very simple for farmers to help us in the process of deploying this microbe and generating carbon dioxide removal... we provide that farmer, free of charge, with the microbes."

- Gonzalo Fuenzalida-Meriz

The Scale Challenge

Andes deployed across 27,000+ acres by 2023. The ambition is gigatonne-scale CO2 removal - which means hundreds of millions of acres. Gonzalo has been candid about where the bottleneck sits: not in the science, not in farmer adoption, but in MRV - monitoring, reporting, and verification.

Measuring carbon outcomes across millions of heterogeneous farm plots, with different soils, climates, crops, and management practices, is a systems problem as much as a scientific one. The MCM Methodology is the foundation, but the measurement infrastructure still needs to scale. It is the problem Gonzalo spends considerable effort on, and it is the problem that will determine whether Andes achieves its stated ambition or stops short of it.

"Our biggest challenge to grow has to do with MRV, with the ability of measuring across millions of acres."

- Gonzalo Fuenzalida-Meriz

A Business Background Running a Science Company

One of the interesting structural facts about Andes is that its CEO is not a scientist. Gonzalo's academic background is in finance and economics. He built his understanding of microbiology through years of working in biological startups, hiring deeply technical people, and developing the judgment to translate between commercial requirements and scientific possibility.

This may explain why Andes' framing is unusually farmer-centric and economically coherent for a climate tech startup - and why the business model was designed from first principles rather than adapted from an existing category. The company's partnerships with Bayer, Cargill, Corteva, and Nutrien suggest that the agribusiness majors see Andes as a credible operating partner, not just a science project seeking distribution.

Gonzalo's vision, stated plainly: use biological tools to fix what industrial agriculture broke. The microbes were always there. The system just hadn't found a way to pay them.

How Microbes Bury Carbon for a Thousand Years

Andes' platform rests on a process called microbial carbon mineralization - a natural geological mechanism the company has engineered to work at agricultural speed and scale.

The key distinction from organic carbon sequestration (which stores CO2 in plant matter and decays over decades) is permanence. Soil inorganic carbon locked into mineral form persists for thousands of years. It does not burn in wildfires. It does not decompose. It does not leak.

The approach also addresses synthetic nitrogen - responsible for roughly 2% of global greenhouse gas emissions - by deploying nitrogen-fixing microbes alongside the carbon-mineralizing strains. One seed treatment, two problems addressed simultaneously.

"For the first time, a farmer can trust that a biological will replace a chemical input because we can guarantee that microbe will interact with the plant."

- Gonzalo Fuenzalida-Meriz
01
Seed Coating

Beneficial microbes are integrated directly into the seed coating (Microprime platform) - corn, soy, canola, or wheat. No extra equipment. No practice change required from the farmer.

02
Plant-Microbe Interaction

Microbes colonize the root zone as seeds germinate. Nitrogen-fixers reduce synthetic fertilizer demand. Mineral-weathering strains interact with soil silicate minerals.

03
CO2 Capture

Microbial activity draws atmospheric CO2 into the soil via accelerated weathering reactions - the same process that stores carbon in geological formations, compressed into agricultural timescales.

04
Mineral Locking

CO2 is converted to soil inorganic carbon (minerals). Stable, non-biological, non-flammable. Verified via pore water DIC measurement and validated under ISO 14064.

05
Carbon Credits

Verified removals are quantified under the MCM Methodology. Credits sold to corporate buyers. Farmer pays nothing. Farmer earns more from yield gains.

Quotes That Explain the Mission

"When you see the miracle of a new person joining the world, a click inside just triggers and this list of things I thought important, I just trash it."

"We want to lock carbon for thousands of years and that is our approach."

"Our vision is using biological tools to fix what we've broken: empowering biology to fight climate change."

"When you think on the broad impact of synthetic nitrogen, it's something that if we have an alternative and we can replace it, we should."

"If we're paying $10 to $15 [per acre in carbon revenue to farmers], basically we're increasing their net income anywhere between 20 and 30%. And that isn't seen in agriculture."

"These microbes have the ability to capture atmospheric CO2. Now with that captured CO2, we measure that and we create carbon credits so people and companies can use those carbon credits."

Five Things Worth Knowing

FACT 01

His degree is in business and finance - not biology. He built one of the most scientifically rigorous microbial carbon removal companies in the world anyway.

FACT 02

Andes gives farmers the microbial seed treatments at zero cost. The entire business model is funded by carbon credits alone. Farmers take no financial risk.

FACT 03

The microbes convert CO2 into soil inorganic carbon - minerals. Unlike organic carbon in plants, this form of storage doesn't decay, doesn't burn, doesn't disappear.

FACT 04

Gonzalo had already founded one biotech company in Chile (Ango - Austral Biologicals, 2013) before Andes - quietly building the instincts that matter while still technically in finance.

FACT 05

Lawrence Livermore National Laboratory - the place that developed nuclear weapons and runs the National Ignition Facility - is one of Andes' research validation partners.
