$30M Series A led by USV will fund Mombak’s expansion from startup to large-scale reforestation platform.

$150M in carbon credit contracts secured—with projections to quadruple in 2024.

Investor momentum builds in Brazil’s carbon removal sector, drawing major corporate offtakers like Google, Microsoft, and Meta.

From startup to reforestation scale-up

Brazilian carbon removal startup Mombak has raised $30 million in Series A funding to advance its reforestation and carbon credit operations across the Amazon rainforest. The round was led by Union Square Ventures (USV), with participation from returning investors Kaszek, Bain Capital, and AXA IM Alts, as well as new backers Lowercarbon Capital and Copa Investimentos.

Founded in 2021, Mombak transforms degraded pastureland into native forests, generating high-quality carbon credits for the voluntary carbon market. The company has already planted five million trees across 45,000 acres and plans to hit eight million trees by June 2025.

“We are moving from startup to scale-up,” said co-founder Gabriel Silva. “It was time to raise new capital to support this next phase of growth.”

Demand for high-integrity carbon credits surges

Mombak’s market momentum is backed by $150 million in carbon removal offtake agreements—with expectations to quadruple in 2024. These credits are already drawing high-profile buyers like Google, Microsoft, Meta, and McLaren Racing, signaling strong institutional interest in Brazil’s nature-based solutions.

Investors betting on carbon removal as a 21st-century industry

The investment underscores Brazil’s emergence as a carbon removal leader, where startups such as Biomas and re.green are also attracting significant funding. The Amazon’s unmatched ecological value and reforestation potential make it central to global climate strategies.

“We believe carbon removal will be one of the defining industries of the 21st century,” said USV Managing Partner Andy Weissman. “We’re proud to support Mombak’s mission to turn the Amazon into a global engine for climate restoration.”
