Mombak delivers Amazon removal credits 2 years early, proving its reforestation bet
Mombak's bet that Amazon reforestation can sell premium carbon credits paid off: 21,000+ credits delivered to Google and McKinsey two years early.
Mombak
What the business is
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.
Starting capital：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.
How it started
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.
What happened
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.
How it ended up
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.
Background
Mombak's bet is that the carbon market's credibility problem is an opportunity: instead of cheap avoided-deforestation offsets, sell high-integrity removal credits from reforesting degraded Amazon pastureland with native biodiversity. Founded in 2021 by Brazilian entrepreneurs Peter Fernandez and Gabriel Haddad Silva, the company acquires or partners on cleared farmland, replants it, and converts verified removals into registry-issued credits for corporate buyers.
The commercial model worked before delivery existed. Microsoft signed in 2023 to buy up to 1.5 million credits; Google followed in 2024 with 50,000 metric tons by 2030, its first South American carbon-removal deal; McLaren Racing bought credits for its net-zero path. In April 2025 Mombak raised a US$30M Series A led by Union Square Ventures with Kaszek, Bain Capital, AXA IM Alts, Lowercarbon Capital and Copa Investimentos, and Reuters reported roughly US$150M in signed offtakes and over US$200M raised since founding.
On 2026-08-04 Mombak announced its first delivery: more than 21,000 tonnes of credits issued after planting nearly 15 million native trees across 12 Amazon farms, going to Google, McKinsey, McLaren Racing, Bain, Climeworks, Commons and Union Square Ventures. Google, McKinsey and McLaren received theirs more than two years before the expected 2028 date, in the first completed delivery under the Symbiosis Coalition (Google, Meta, Microsoft, Salesforce). A further issuance of about 55,000 credits is planned for late 2026.
What has to be true
- 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.
What can be applied
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.
Aftermath
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.
