Mombak delivers Amazon removal credits 2 years early, proving its reforestation bet

Mombak buys or partners on degraded Amazon pastureland, replants it with native biodiverse species, and sells the verified carbon-removal credits to corporate buyers like Microsoft, Google and McKinsey.

That Big Tech would pay for high-integrity Amazon reforestation credits delivered on time, not cheap avoided-deforestation offsets, making restoration itself a business.

US$30M Series A led by Union Square Ventures, announced 2025-04-28, with Kaszek, Bain Capital, AXA IM Alts, Lowercarbon Capital and Copa Investimentos; Reuters reported over US$200M raised since founding by May 2025, plus a US$17.8M Santander Brasil/BNDES climate-fund commitment.

Founded in 2021 by Brazilian entrepreneurs Peter Fernandez and Gabriel Haddad Silva, Mombak bet that restoring cleared Amazon pastureland with native, biodiverse forest could produce carbon removal credits credible enough for global corporate net-zero budgets — a bet on the high-integrity end of a market then dominated by cheap avoided-deforestation offsets.

In 2023 Microsoft agreed to buy up to 1.5 million removal credits from Mombak, and McLaren Racing bought credits as part of its net-zero plan. In 2024 Google signed for 50,000 metric tons by 2030 — its first carbon-removal partnership in South America — and Mombak became the first nature-restoration project selected by the Symbiosis Coalition (Google, Meta, Microsoft, Salesforce). A US$30M Union Square Ventures-led Series A followed in April 2025 as the company moved from startup to scale-up, with Reuters reporting signed offtake contracts worth about US$150M at that point and over US$200M raised since founding.

Still running and scaling: on 2026-08-04 Mombak announced delivery of its first Amazon credits — more than 21,000 tonnes issued after planting nearly 15 million native trees across 12 farms — to buyers including Google, McKinsey, McLaren Racing, Bain, Climeworks and Union Square Ventures, with Google, McKinsey and McLaren receiving credits more than two years before their expected 2028 delivery. A further issuance of about 55,000 credits is planned for late 2026.

A legible, dated arc: founded 2021, Microsoft offtake 2023, Google deal 2024, US$30M USV-led Series A in April 2025, then the first 21,000+ credit delivery in August 2026.

The contrarian bet is concrete: high-integrity Amazon reforestation credits, not cheap avoided-deforestation offsets, would win corporate net-zero budgets.

Numbers are specific and sourced: 1.5M-credit Microsoft agreement, 50,000-ton Google deal, ~US$150M offtakes, US$30M Series A, ~15M trees on 12 farms, 21,000+ first issuance.

The outcome is legible: first credits delivered two years ahead of schedule, validating a market where late and short deliveries had damaged buyer confidence.

Integrity-first products can be financed before delivery — offtakes funded years of planting — but trust is re-earned per issuance, so early verified delivery became its strongest marketing asset.

As of 2026-09-02 Mombak is scaling rather than sold or shut down: it has planted nearly 15 million native trees across 12 Amazon farms, delivered its first 21,000+ removal credits to corporate buyers two years early, and plans a larger issuance of about 55,000 credits in late 2026. The company still needs to prove that early delivery repeats at much larger volumes while verification quality and land safeguards hold, which the late-2026 issuance is expected to test.
