Mombak
Mombak is a Carbon Removal (CDR) company founded in 2021 and based in São Paulo, Brazil.
Mombak was founded in 2021 in São Paulo by Peter Fernandez, former CEO of ride-hailing company 99, and Gabriel Haddad Silva, former CFO of Nubank. It buys degraded pastureland in the Brazilian Amazon, replants it with native tree species, and sells carbon removal credits under long-term offtake agreements. Microsoft agreed in December 2023 to buy up to 1.5 million credits for delivery by 2032, and Google agreed in November 2025 to buy 200,000 tonnes through the Symbiosis Coalition. Mombak finances planting through dedicated funds. Its initial fund raised $120 million and supported reforestation on 15 farms. In September 2026 it reached an initial close on a second fund targeting $150 million and secured a $40 million credit line from Brazil's development bank BNDES. It began delivering reforestation credits in July 2026 under Isometric's Reforestation Protocol, more than two years ahead of contracted deadlines.
Mombak gives the sector a nature-based removal supplier with buyers including Microsoft, Google, Salesforce and McKinsey. Its July 2026 issuance went to buyers including Google, Bain, Climeworks and McLaren Racing. It has planted nearly 15 million trees across 15 Amazon farms and expects to issue more than 100,000 tonnes of credits in 2026.
