Naturally occurring minerals - alongside forests, soils, and the ocean - are one of our planet's most vital carbon sinks. Over geological timescales, carbon dioxide in the air and water chemically bind to these minerals and permanently turn to stone.

Our technology enhances this natural process, called carbon mineralization, to help minerals absorb CO2 from the ambient air in days, rather than years. By combining the best of engineering and nature, we can offer the most cost-effective and scalable Direct Air Capture solution in the world.

I'm most passionate about inspiring and unleashing others'​ creative potential and channeling it to our most pressing challenges. I love building technology companies because they lie in the intersection of the most profound imagination of tomorrow, and today's imperfect reality.

At Heirloom, our mission is to accelerate our planet's transition to a carbon negative society. Our goal is to remove 1B tons of CO2 from the air by 2035 by engineering the most cost-effective, scalable direct air capture system.
