Halifax-based climate technology firm pHathom Technologies has closed a $4 million seed financing round to advance carbon capture for coastal bioenergy and industrial facilities. The round was led by Propeller Ventures, with participation from the New Brunswick Innovation Foundation, Invest Nova Scotia, and Carmeuse Ventures.
Founded in 2024 by Dr. Kimberly Gilbert, pHathom captures biogenic carbon dioxide and converts it into stable dissolved inorganic carbon using existing infrastructure. Combined with its role in a $16 million Ocean Supercluster project, pHathom’s total committed capital now exceeds $12 million. The funding will support pilot deployments, scientific validation, and regulatory work for durable, verifiable carbon storage.
