A conversation with Mary King, Vice President at Aligned Climate Capital
The Quiet Resilience of Climate Infrastructure
Venture capital has historically gravitated toward breakthrough tech and high-growth SaaS margins. But in the current climate market — where risk, policy, and execution barriers dominate — the most attractive returns may come from infrastructure that simply does its job.
Aligned Climate Capital stands out by investing not in moonshots, but in climate solutions that deliver steady, infrastructure-style returns — often without relying on volatile subsidies. Mary King, Vice President at the firm, has been leading investments into distributed energy developers, DER orchestration and O&M providers, decarbonization technology, and similar solutions.
In this Q&A, King explains what it means to be “infrastructure-aligned” in today’s venture world, why policy risk must be priced correctly, and how AI is unlocking new optimization layers in the climate stack.
1｜Infrastructure-Aligned Capital Doesn’t Mean Bleeding-Edge Tech
Net Zero Insights: Aligned Climate Capital often describes its portfolio as “infrastructure-aligned.” What defines that for you?
Mary King: Generally supporting the deployment of infrastructure. That could be infrastructure developers like Summit Ridge or BrightNight, or tech providers with a development angle — including differentiated process engineering— in an emerging decarb asset class like XGS (geothermal) or CarbonQuest (point source carbon capture). Sometimes it’s also companies selling into the infrastructure industry, like EVenergi or ChargerHelp.
It’s not about capital intensity — we actually quite like distributed, lower-capex infrastructure and low capex solutions serving infrastructure.
Net Zero Insights: So your portfolio avoids “bleeding-edge” in the deep tech sense?
Mary King: We don’t back bleeding-edge tech, but many of these things are bleeding-edge from a commercialization perspective.
Some of our companies are the first to bring solutions to market, serving new asset classes or enabling unique financing. If the unit economics work, the solution solves a real pain point, and there’s willingness to pay — or the company has found a way to finance the solution sustainably for customers — we’re interested.
2｜Commercial Logic, Not Just Carbon Math
Net Zero Insights: Your thesis centers on “subsidy-independent” infrastructure. What does that mean in underwriting?
Mary King: Company by company, it depends on how much a business relies on incentives for unit economics to work — and how risky those subsidies are.
If a company is highly reliant on a subsidy but the incentive is crystal clear and low risk, that’s okay. That’s how the oil and gas industry has always operated. But if the subsidy is risky, then it needs to be treated as upside — we can’t underwrite to it.
Net Zero Insights: Are there benchmarks you look for on revenue, margins, or asset IRRs?
Mary King: It really depends. But generally we say $1 million+ revenue for software, $5 million+ for hardware, and at least one commercially deployed, non-pilot project with a healthy late-stage pipeline.
For infrastructure companies, if there’s a pipeline of fully contracted asset showing an attractive IRR, we pay attention. It also depends on scalability and counterparties. In some cases, the team itself is a major de-risking factor.
Net Zero Insights: What are the best signals for scalable, decentralized infrastructure?
Mary King: Attractive unit economics, clear counterparty dynamics (customers, site hosts, off-takers), strong demand but not a “luxury” solution, and ideally IRRs strong enough for third parties to want to own the assets.
3｜Looking Ahead: Where Climate Infrastructure Capital Is Flowing
Net Zero Insights: You’ve emphasized states like California and New York. Any new geographies catching your eye?
Mary King: The best states and municipalities depend so much on the asset type, need, and policy — and increasingly, the best geographies are not always in the U.S. Some of our companies are finding a lot of success in Canada, Europe, Asia, and Australia.
Net Zero Insights: And what about AI? How does it intersect with your thesis?
Mary King: It’s already reshaping a lot of workflows: grid studies, supply chain management, project design and engineering, etc. These are the kinds of areas we’re watching — they align really well with our view of climate infrastructure that can scale.
Net Zero Insights: Lastly — what do founders and co-investors still misunderstand about your strategy
Mary King: That it’s usually a different style of investing from Silicon Valley. The next stage is almost never IPO. Often, it’s about building real infrastructure, and exits could come from strategic acquisition, infrastructure/PE acquisitions, and even asset sales and distributions in the case of developers.
Final Word: Real Assets, Real Returns
At a time when many venture firms are recalibrating their climate theses, Aligned Climate Capital continues to quietly build a portfolio around what works — not what merely promises to.
Its strategy offers a valuable lens for U.S. investors seeking durability over hype, and for founders aiming to build in sectors where bankability, customer demand, and policy foresight matter more than unicorn valuations.
