We accelerate mineral weathering by spreading basalt on croplands to increase dissolved inorganic carbon with eventual storage as ocean carbonates. Our technology uses novel soil models and machine learning to maximize CO₂ removal while boosting crop growth. Removed carbon is tracked from the farm to rivers and the oceans, monitoring for permanence and additionality.
How it Works: Basalt is applied to farmland with a spreader.
Basalt reacts with rainwater, converting atmospheric CO2 to dissolved bicarbonate and releasing macro- and micronutrients to the soil. Lithos measures this empirically with our high-accuracy proprietary approach.
Dissolved bicarbonate is transferred by rivers and streams to the coastal ocean, where it is stable for thousands of years. Lithos monitors for leakage in river networks and tracks the carbon in a cradle-to-grave lifecycle.
Eventually, dissolved bicarbonate reacts to form calcium carbonate minerals that are permanently deposited at the ocean floor.

She comes from a background in soil chemical kinetics, analytical instrumentation, and statistical modeling with projects at the US EPA and the DOE’s Advanced Photon Source. She’s also spent time as a farm hand in North Carolina! Lily holds a MS in Environmental Engineering from University of Wisconsin Madison and a BS in Energy, Environmental, and Chemical Engineering from Washington University in St. Louis.
Mark Baum, PhD
Researcher, Silicate Weathering
Mark drives research and computational modeling at Lithos. Before joining the team, Mark published research on the silicate weathering and carbon cycle. Today, Mark is applying his expertise in climate physics, hydrology, machine learning, and numerical modeling to develop and productionize Lithos’ foundational models. Previously, Mark also worked as an environmental science & engineering consultant, developed devices for clay mineral characterization at NASA JPL, and published an open-source Python library with 24k downloads! Mark earned his PhD in Earth & Planetary Sciences from Harvard University while studying silicate weathering, along with a BA in Physics and Earth Sciences from Dartmouth College.
Johannes Tyralla
Head of Growth
Johannes leads growth and farmer experience at Lithos. Before Lithos, Johannes spent a decade in food and agriculture, working alongside row crop and subsistence farmers globally and then building early operations and strategy teams at Afresh. He earned his MBA and Masters in Environment from Stanford University and is thrilled to help growers boost their profitability while capturing carbon out of the air.
Jonny Lu
Head of Carbon Strategy
Jonny drives carbon removal demand and strategy for Lithos. He started his career in consulting and spent the past 5 years advising incubated startups and leading corporate strategy at Google. Recently he scaled up a 300+ person regulatory program and managed the strategy & operations team of Google's Chief Compliance Officer. Jonny lives in the Pacific Northwest and loves hiking through the North Cascades. He earned his MBA from Carnegie Mellon University and Bachelor’s in Accounting from the University of Washington.
Quentin Servais-Laval
Head of Operations
Quentin heads up Operations & Logistics as we rapidly and responsibly scale our carbon removal supply chain. Before Lithos, Quentin spent over a decade leading teams in Finance and Operations in five countries. His career kicked off with the LVMH group, handling budgets over $50 million. He then helped Instacart break into Canada, expanding it to cover 60% of Canadian households in under a year. Later, he spent four years growing the Finance and Operations teams of a tech-driven labor marketplace from just one person to a team of 250, raising two rounds of funding. Quentin boasts Master's degrees from Ecole Centrale and HEC Paris (FT's #1 European Business School). He speaks French, English, and Spanish. Outside work, Quentin's an adventurer at heart, exploring hidden trails and competing in triathlons.
Ben is our Chief of Staff at Lithos and is plugged into everything from quarry sourcing, rock deliveries, to our grower experience! Part of Ben’s passion comes from his roots: his family were wheat farmers in eastern Washington. Ben studied Environmental Science at the University of Washington and prior to Lithos had an accomplished career in logistics, supply chain, systems innovation, and analyzing data for brands including Costco, Brooks Running, Convoy, and Henkel. In his free time, he climbs rocks, including the basalt pillars in Vantage, WA! He is excited to be a part of Lithos and to be scaling our tech as quickly as possible.
Shane drives growth acceleration at Lithos, focused on scaling our approach to developing relationships with farmers whom we deeply partner with. Prior to Lithos he has worked as a consultant at Bain & Co. His cases there included landscape-scale reforestation strategy and enterprise tech growth strategy. He is a graduate of Princeton University in Economics with certificates in Finance, Neuroscience, and Cognitive Science. He loves the great outdoors and is excited to work towards a more sustainable future!
