Putting waste to work removing carbon
Vaulted Deep is a waste management and carbon removal company that permanently sequesters carbon-filled organic waste by injecting it deep underground using geologic infrastructure. Founded in 2023 by Julia Reichelstein and Omar Abou-Sayed, the company collects organic waste from farms, cities, and industries and converts it into a slurry injected up to 5,500 feet underground, protecting local land, air, and water while removing carbon from the atmosphere. Vaulted signed one of the largest carbon removal offtake deals ever with Microsoft in July 2025 and won $8 million as a runner-up in the XPRIZE Carbon Removal competition. Headquartered in Houston with operations in San Francisco and Kansas, the company has a team of 70+ people.
