Vaulted Deep
Vaulted Deep is a Carbon Removal (CDR) company founded in 2023 and based in Houston, United States. It has raised $35M in total funding, most recently a Debt in 2026.
Vaulted Deep was founded in 2023 and is headquartered in Houston, United States. The company collects nonhazardous organic waste—including biosolids, paper-mill sludge, manure, and crop residues—and injects it as slurry thousands of feet underground into stable geologic formations, permanently sequestering the carbon contained in that material. The process adapts decades-old slurry-injection well technology to carbon removal while solving costly waste-management problems for municipalities and industry. Vaulted Deep generates revenue by selling durable carbon-removal credits to corporate buyers. The company has raised $35 million in debt financing as of September 2026.
Vaulted Deep operates in carbon dioxide removal (CDR), a sector attracting significant capital mobilization; a 2026 Frontier coalition funding announcement raised $915 million for carbon removal work and expanded participation among major technology companies. Vaulted Deep's $35 million debt round in September 2026 reflects investor confidence in the commercial viability of its waste-to-sequestration approach as a carbon removal pathway.
