Gigablue Announces $20 Million Series A First Close at Davos 2026
Marking a New Era for Marine Carbon Removal as Economic Infrastructure
January 2026
Davos, Switzerland — World Economic Forum
Gigablue, a marine carbon dioxide removal (mCDR) company developing science-based solutions to restore ocean health while addressing climate change at scale, today announced the successful $20 million first close of its Series A financing, unveiled during the World Economic Forum Annual Meeting in Davos.
The round was led by Planet Ocean Capital, following an extensive, months-long technical, scientific, and environmental due-diligence process. The financing was joined by a group of mission-aligned venture capital firms and family offices united by a shared conviction: that durable carbon removal and healthy oceans are becoming foundational infrastructure for the global economy and a critical enabler for meeting the hard-to-abate emissions of the rapidly growing energy demand driven by data centers, AI, and digital infrastructure.
Founded in 2022, Gigablue develops and deploys a marine carbon removal pathway based on Microalgae Carbon Fixation and Sinking (MCFS) - a methodology formally released by the Puro.earth Advisory Board in September 2025 following comprehensive scientific review and public consultation. MCFS mirrors the ocean’s natural biological pump, the planet’s largest long-term carbon sequestration system, enabling long-term atmospheric carbon removal through natural marine processes.
Gigablue’s technology is designed to be measurable, scalable, and environmentally responsible. Each deployment is supported by a robust Measurement, Monitoring, Reporting, and Verification (MMRV) framework integrating in-situ oceanographic data, environmental DNA sampling, water chemistry analysis, and custom deep-sea monitoring tools. This ground-truth scientific evidence underpins Gigablue’s commitment to transparency and environmental integrity as the company advances toward issuing high-quality carbon removal units.
The Series A first close was announced during an invitation-only Davos 2026 dinner convened within the official WEF security zone, titled:
“Game On: Investing in Nature, Carbon Removal & the Future of Sport — How Nature, Sport, and Capital Are Shaping the Next Infrastructure of Value.”
Hosted at the Mastercard TechLodge in partnership with Leaders on Purpose, Hub Culture, and the Didier Drogba Foundation, the evening brought together senior leaders from global capital markets, sport, cities, and climate innovation to explore how nature and permanent carbon removal are emerging as balance-sheet-relevant infrastructure — not externalities.
The event positioned Gigablue’s announcement within a broader systems conversation: how value is defined, what is treated as economic infrastructure, and how institutions capable of mobilizing both capital and culture can accelerate the next phase of global resilience. The dinner was held under the Chatham House Rule and convened 30 senior decision-makers across finance, sport, and climate leadership.
“High-integrity carbon removal is increasingly recognized as essential alongside emissions reductions,” said Gigablue leadership. “This first close reflects growing confidence that marine carbon removal — when governed by science, transparency, and environmental safeguards — can play a critical role in achieving global net-zero targets while strengthening ocean health.”
The participation of Planet Ocean Capital, alongside leading climate-focused family offices, underscores investor confidence in Gigablue’s ability to responsibly scale its technology toward gigaton-level impact, while maintaining rigorous scientific oversight and ecological protection.
Proceeds from the Series A first close will support:
Continued scaling of Gigablue’s MCFS deployments
Expansion of MMRV and deep-sea monitoring capabilities
Advancement toward commercial issuance of high-integrity carbon removal units
Progress toward the second close of the Series A round, currently underway
As governments, corporations, and financial institutions confront the reality that climate stability depends on both emissions reductions and atmospheric carbon removal, Gigablue is building the scientific, operational, and institutional foundations required to make marine carbon removal a durable global solution — supporting hard-to-abate sectors, national climate strategies, and long-term planetary resilience.
