Mangrove Systems Acquires Grain Ecosystem to Strengthen Biochar MRV Platform

Mangrove Systems has acquired select operating assets from Grain Ecosystem, a digital biochar project development platform focused on the North American market, in a move that significantly expands Mangrove's footprint in the biochar carbon dioxide removal (CDR) space.

As part of the deal, Mangrove is taking over Grain's customer base of biochar operators, bringing them onto its compliance and monitoring, reporting, and verification (MRV) platform.

Grain played a foundational role in building the North American biochar market. By absorbing its portfolio of operators, Mangrove is positioning itself as the compliance platform of choice for CDR operators looking to scale. Over a third of the global biochar carbon market already runs on Mangrove's digital MRV solution, and this acquisition pushes that share even further.

Grain's operator accounts will now access Mangrove's full platform capabilities, including automated data ingestion, AI-assisted carbon accounting, end-to-end audit-ready reporting, and expert certification support aligned with leading compliance and voluntary programs.

Ryan J. Letourneau, Co-Founder and CEO of Grain Ecosystem, said: "Grain has built a strong platform and market presence in the biochar sector, and we believe Mangrove is well positioned to carry that work forward. This transaction provides continuity for customers and reflects a strong fit between what Grain built and Mangrove's long-term platform."

Annie Nichols, General Manager of Biochar at Mangrove Systems, added: "Biochar is one of the most promising and fastest-growing segments of the carbon removal market, and this acquisition deepens our commitment to it. We're proud to welcome Grain's operators onto our platform and to support them with the MRV infrastructure they need to scale their revenue and impact."
