$100M+ blue economy fund launches in Canada, Isometric raises $40M to expand agentic certification, Frontier commits $915M to carbon removal
Welcome back! This week we're looking at new growth capital flowing into Atlantic Canada's blue economy, plus two stories about carbon – one a $40M raise expanding AI carbon certification and the other on Big Tech's growing bet on reducing carbon in the sea.
🇨🇦 AtlantiCan Growth Partners launches with $100M+ target for blue economy fund
AtlantiCan Growth Partners (AGP) launched today as a long-term investment platform built to close Atlantic Canada’s growth capital gap. The Halifax-based firm runs an operator-led model, partnering with founders and operators in sectors where the region holds a strong global position, including aquaculture, marine technology, fisheries, and ocean innovation. Atlantic Canada has drawn just 2% to 3% of national venture capital over the past five years, with most deployment going to Ontario and Quebec.
AGP plans to launch three dedicated funds over time, starting with a $100 million to $150 million vehicle focused on the blue economy. The firm is led by President and CEO Alex McCallum and Executive Chairman Telfer Hanson, who spent three decades in international investment banking before shaping AGP’s strategy. AGP is now seeking founders, co-investors, and institutional partners aligned with long-term regional growth.
🏭 Isometric raises $40M to expand AI-driven certification beyond carbon markets
Isometric raised $40 million in Series A funding to scale its agentic certification platform. AVP led the round, and existing backers Plural and Lowercarbon Capital returned, alongside personal investment from John Doerr and Walter Kortschak. The premise is that a tonne of green steel looks identical to conventional steel, but certification is what makes these claims verifiable. Its platform, Certify, uses AI agents to cross-check the data behind those claims, cutting a process that used to take 12 months down to hours.
Isometric built its track record in carbon removal, where it’s now the largest certifier with more than 16 million tonnes contracted. Its marine work includes issuing the first independently verified credits from ocean alkalinity enhancement and certified protocols for Direct Ocean Capture & Storage. With this raise, Isometric is the best-capitalized certifier in carbon markets and is extending Certify to the rest of the industrial economy.
🤝 Frontier commits $915M more to carbon removal, with ocean-based methods among its priorities
Frontier is a coalition of major companies like Google, Stripe, Shopify, Salesforce, and now Anthropic, that promise to buy carbon removal credits in advance so the companies producing them can raise money and scale faster. Frontier just added $915 million to that pool, bringing its total commitment to $1.8 billion since launching in 2022. One method it’s betting on is ocean alkalinity enhancement, which adds a limestone-based material to seawater so the ocean can absorb more carbon dioxide from the air, an approach Frontier believes could eventually scale to over 10 billion tons removed per year.
Getting there would mean building out coastal outfalls and ships to spread the material across the open ocean, along with better tools to confirm it’s working safely. Rather than spreading money across many small, early-stage projects as it has in the past, Frontier is now concentrating on fewer companies through longer 8 to 10 year purchase agreements, each requiring a credible path to long-term demand. Its portfolio has delivered roughly 23,000 tons of carbon removal so far, double the year before, and it has published safety guidelines specifically for marine carbon removal projects.
