# Mombak: A Technology-Driven Carbon Removal Company
Mombak is not primarily a technology company—it is a carbon removal company that leverages technology as a core operational tool. Founded in 2021, Mombak focuses on large-scale reforestation in the Brazilian Amazon, restoring degraded pastureland with native, biodiverse tree species to generate high-integrity carbon removal credits[1][2]. The company's mission is to become the world's largest carbon removal company by combining expertise in science, technology, forestry, and carbon markets[3].
Mombak's business model centers on creating, verifying, and selling carbon removal credits generated from reforestation activities[2]. It serves corporate buyers—including Microsoft and Google—seeking premium, high-quality carbon offsets, while simultaneously delivering co-benefits such as biodiversity restoration, improved water resources, and job creation in local Brazilian communities[1]. The company operates as a fully vertically integrated enterprise, handling everything from planting to monitoring to credit sales, which ensures quality and transparency throughout the value chain[1].
Mombak was founded in 2021 by Peter Fernandez (former CEO of 99, Brazil's first unicorn) and Gabriel Silva (former CFO of Nubank, Brazil's first "decacorn")[2]. Both founders brought deep technology and business scaling expertise to tackle climate change through nature-based solutions. The company emerged from a recognition that traditional carbon markets lacked high-integrity, large-scale reforestation projects—a gap the founders sought to fill by applying their tech backgrounds to forestry and carbon markets[2].
Early traction came quickly. Mombak signed landmark contracts with major technology companies including Microsoft and Google[1]. A pivotal moment occurred when the company issued a $225 million outcome bond with the World Bank—the largest ever in its category—with $36 million allocated to Mombak's reforestation activities, validating the company's model and setting a new market precedent[1]. By the time of these announcements, Mombak had already planted over 10 million seedlings across ten farms in four locations, employing more than 350 people[1].
Mombak represents a convergence of three major trends: the climate tech boom, the maturation of carbon markets, and the application of machine learning to environmental challenges. The company sits at the intersection of climate finance innovation and nature-based solutions, riding growing corporate demand for credible carbon offsets as net-zero commitments become standard among large enterprises[1][2].
The timing is critical: carbon markets have historically suffered from integrity issues and lack of investable projects at scale. Mombak's success—evidenced by World Bank partnerships and blue-chip investor backing—signals that technology-enabled, vertically integrated carbon removal can achieve both financial returns and environmental impact[2]. The company's use of machine learning to optimize reforestation at industrial scale demonstrates how software and data science can unlock efficiency gains in traditionally low-tech sectors.
Mombak's influence extends beyond its own operations: by proving a scalable, transparent model for nature-based carbon removal, it raises standards across the industry and attracts institutional capital (including impact investors like The Rockefeller Foundation) to climate solutions[2].
Mombak is positioned to become a category leader in the emerging carbon removal economy. The company's founders brought proven scaling expertise from Brazil's tech unicorns, and early validation from marquee customers and institutional investors suggests the model works. Key challenges ahead include maintaining carbon credit quality as the company scales, navigating evolving carbon market regulations, and competing with other nature-based and technological carbon removal approaches.
The next phase will likely involve geographic expansion beyond Brazil, continued R&D to improve tree genetics and yield, and potentially going public or achieving unicorn status—fitting the trajectory of its founders' previous ventures. As corporate net-zero commitments drive demand for high-integrity offsets, Mombak's combination of technology rigor, operational control, and environmental credibility positions it to capture significant market share in a sector that will only grow in importance.
Mombak has raised $30.0M across 1 funding round. Most recently, it raised $30.0M Series A in April 2025.
