Gigablue

Based in the US, Gigablue specializes in ocean-based carbon sequestration solutions, utilizing a unique technology to capture and store carbon dioxide from the atmosphere effectively. Founded in 2022 and headquartered in New York, US, Gigablue focuses on innovative carbon solutions. The company has completed one deal, securing USD 20. 00 mn in Series A funding led by Planet Ocean Fund on January 26, 2026.

The founder's prior ventures are not publicly referenced. Gigablue specializes in innovative carbon sequestration solutions through its proprietary Microalgae Carbon Fixation and Sinking (MCFS) method. This technology leverages microalgae to capture carbon dioxide from the atmosphere and transport it to the deep ocean, where it remains stable for extended periods. By utilizing an oceanographic intelligence platform, Gigablue identifies optimal deployment zones and tailors substrate-particle compositions to maximize carbon capture efficiency.

The company aims to support major corporations and governments in achieving their net-zero targets, addressing the pressing climate challenge on a large scale. Their services cater to a diverse client base, including environmental organizations, governmental agencies, and private sector enterprises involved in sustainability initiatives across North America, Europe, and parts of Asia. Gigablue generates revenue through strategic partnerships and B2B transactions within the carbon removal ecosystem. The company collaborates with impactful organizations and stakeholders to implement its MCFS solutions, which may involve contractual agreements for the deployment of its technology in various geographical markets.

Revenue streams are derived from service agreements that outline specific deliverables and performance metrics, ensuring accountability and effectiveness in carbon capture efforts. Clients typically engage in long-term contracts that cover the deployment, monitoring, and optimization of carbon sequestration initiatives, fostering a sustainable business model centered on environmental impact and regulatory compliance. Looking forward, Gigablue plans to utilize the recent USD 20. 00 mn raised in Series A funding to deploy additional microalgae units and enhance its monitoring, reporting, and verification capabilities.

The company aims to issue carbon credits and pursue a second close of its Series A. Furthermore, Gigablue targets expansion into new markets, specifically enhancing its reach within Europe and parts of Asia by the end of 2026.
