ArcTern Ventures is a global venture capital firm founded in 2012 with headquarters in Toronto and offices in San Francisco and Oslo. The firm partners with entrepreneurs developing technology solutions to address climate change and sustainability challenges. Drawing on the operational and startup experience of its partners, ArcTern aims to generate strong financial returns while driving measurable reductions in greenhouse gas emissions. As a Certified B Corporation and signatory of the Principles for Responsible Investment, the firm integrates environmental metrics into its decision-making process from initial screening through follow-on support.
ArcTern concentrates on early-stage companies, typically at Series A or B, in sectors that include renewable energy, energy efficiency and storage, circular economy technologies, advanced materials and manufacturing, sustainable mobility and food systems. Investments are guided by rigorous assessments of potential climate impact and scalability. The firm’s third fund raised $335 million, drawing commitments from major institutions, and emphasizes long-term emissions abatement. ArcTern typically writes initial checks of around $4 million, reserving capital for additional rounds in companies that meet their performance and impact thresholds.
Within its clean technology portfolio, ArcTern supports ventures delivering both environmental benefits and growth potential. In battery technology, the firm led a $17.5 million Series A2 financing for Liminal, which offers EchoStat inspection systems to improve safety and performance in electric vehicle battery production. The firm also backed King Energy’s $10 million round, fueling solar installations and OneBill software that simplifies energy billing for multi-tenant commercial buildings. These investments reflect ArcTern’s focus on solutions that lower carbon output and accelerate the transition to a low carbon economy.
