Industrial emissions make up roughly a quarter of global CO₂ emissions, yet many of the most promising climate tech companies remain largely unknown outside specialized circles. This episode explores 95 startups attacking some of the hardest decarbonization challenges across steel, cement, chemicals, heat, fuels, mining, and manufacturing.In addition, I cover one startup turning solar into a 24/7 firm, clean power.Industrial heat is becoming a major battleground — Companies are replacing fossil-fuel-fired boilers and furnaces with thermal batteries, electrified heat systems, and long-duration energy storage solutions.Cement and concrete innovation is scaling — Startups are reducing process emissions through alternative chemistries, carbon mineralization, supplementary cementitious materials, and low-carbon production methods.24/7 solar and clean power are emerging as a new category — Companies are combining solar, storage, and dispatchable energy systems to deliver around-the-clock clean electricity rather than intermittent renewable generation.Steel and metals are entering a new era — Entrepreneurs are commercializing green hydrogen, electrolysis, scrap optimization, and novel production pathways to lower emissions from some of the world's most carbon-intensive industries.Chemicals and fuels are being reinvented — Companies are developing sustainable feedstocks, e-fuels, carbon utilization technologies, and alternative chemical manufacturing processes.The winners may not be the most obvious companies — Industrial markets reward reliability, economics, and operational simplicity, meaning some of the biggest future climate tech successes may emerge from sectors receiving far less attention than AI, EVs, or consumer technologies.--Join our confidential CEO community.Private CEO group for VC/PE-backed climate tech founders navigating capital, strategy, and scale.

Embedding batteries into appliances to bypass big bottlenecks: home electrical upgrades. Instead of rewiring buildings, Copper turns induction stoves into distributed energy assets that can also support the grid.Copper is building appliances with integrated energy storage, starting with Charlie, a 30” induction stove with a built-in battery. The company focuses on making electrification cheaper, faster, and easier for multifamily buildings and older housing stock.They've received $60M in equity funding and government contracts so far.Before co-founding Copper, CEO Sam Calisch helped launch Rewiring America, was an Activate Fellow, co-authored Electrify, and previously founded Elmworks. He earned his PhD from MIT’s Center for Bits and Atoms.Here’s what we discussed:Installation arbitrage that changes adoption economics – Traditional induction stoves often require expensive 240V upgrades and panel work, while Charlie plugs into an existing 110V outlet behind most gas stoves using an onboard 5kWh LFP battery to deliver high-power cookingMultifamily as the wedge market – Buildings facing costly gas infrastructure repairs can avoid six-figure retrofit costs, with some projects saving over $100k by switching directly to Copper’s battery-enabled electric appliancesAppliances as grid assets – Aggregated stoves participate in California’s DSGS virtual power plant program, providing dispatchable capacity during peak demand and potentially offsetting future appliance costsLicensing instead of building everything alone – Copper is pursuing partnerships with incumbent appliance manufacturers rather than vertically integrating every product category itselfFounder operating system – Weekly written goals, deliberate “play time” for experimentation, outdoor activity, and separating business problems from personal identity to sustain long-term decision quality--Join our confidential CEO community.Private CEO group for VC/PE-backed climate tech founders navigating capital, strategy, and scale.

Eric Ries is the author of Lean Startup (millions of copies sold), serial founder, ex-EIR at Harvard, and author of a new book: Incorruptible: Why Good Companies Go Bad and How Great Companies Stay Great.Why is this relevant? Most climate startups optimize for growth and capital, not governance. That’s how mission-driven companies get sold, diluted, or pointed in the wrong direction over time.From the book summary: “Drawing on two decades of work with founders, CEOs, investors, and institution builders, Ries shows how these failures arise predictably, and how they can be prevented. He reframes corporate governance not as bureaucracy or compliance, but as a creative and strategic act at the heart of building enduring, mission-controlled companies.”Why it mattersMost climate founders focus on product, capital, and growth. Almost none design governance early. That’s how companies built to solve climate problems end up owned by actors working against them.In this episode:The Lean Startup breaks at mission scale – MVPs and rapid iteration work early. But mission-driven companies need a long-term philosophical foundation to survive the “flat part of the curve.”Success creates a dangerous new asset: trust – Mission-driven companies generate outsized trust with customers, employees, and society. That trust becomes exploitable as companies scale.The system is designed to extract, not protect – Delaware C-Corps are legally oriented toward shareholder value maximization. Over time, this pressures companies to trade mission for liquidity.The Revlon Doctrine is the forcing function – Once a company is for sale, boards must choose the highest bidder. Even if it destroys the original mission.Real example: mission failure at scale – A UK therapeutics company was sold to a tobacco firm offering a slightly higher bid. Within ~3 years, ~$900M in value was wiped out.Quick fix most founders ignore – Converting to a Public Benefit Corporation (PBC) can be done with a simple filing. It allows balancing mission and shareholder value. Only ~5–10% of climate companies have done this.Advanced structures for long-term control -  Foundations, trusts, and employee ownership models preserve mission across decades. Data across ~54,000 companies shows better growth, retention, and resilience.Investor objections are often weak - “It’s unusual” or “others won’t like it.” But climate investing is already a non-consensus bet. Governance should be, too.--Join our confidential CEO community.Private CEO group for VC/PE-backed climate tech founders navigating capital, strategy, and scale. Capped at 45 CEOs.

The discussion draws on insights from leading climate investors, including Voyager Ventures, Decarbonization Partners, MassMutual Ventures, SOSV, SJF Ventures, Energy Impact Partners, Spring Lane Capital, Climate Insiders, and Tailwind.Examples of what we discussed:Clarity beats complexity – If a non-expert cannot explain your differentiation after one conversation, your positioning still needs workLead with the risks – Founders who proactively surface weaknesses build trust faster than those who hide themDesperation is visible – Targeted fundraising and calm execution outperform broad outreach and forced urgencyAnd also...The $1T Industrial Heat Problem Most Startups Underestimate | TempoIndustrial heat is one of the largest decarbonization opportunities in the world. This second portion explores how to commercialize hard-tech infrastructure without falling into the common traps that slow adoption.Pasquale Romano is the CEO of Tempo and a four-time CEO with multiple successful exits. He shares lessons from building and scaling industrial energy businesses.Examples of what we discussed:Avoid rip-and-replace projects – Technologies that integrate with existing infrastructure face dramatically lower adoption barriersDesign for logistics first – Shipping, installation, and transport constraints often determine scalability more than technology performanceStart with narrow deployments – One successful plant can become the proof point that unlocks broader adoption--Join our confidential CEO community.Private CEO group for VC/PE-backed climate tech founders navigating capital, strategy, and scale.

When expansion feels like productivity, climate CEOs often drift into adjacent markets, new products, and endless “opportunities” that quietly dilute execution.This episode breaks down three strategic traps: timid visions, distraction disguised as growth, and rebuilding too late. Here’s what we discussed:Manifestos vs. marketing decks – Why some climate companies raise billions by selling an inevitable future, not just a product roadmap or pilot projectOpportunity overload – How “adjacencies” like new geographies, EV charging, or development capital can become strategic debt instead of growthFocus as competitive advantage – Why the best operators often win by doing fewer things deeper while competitors chase every inbound requestWhen to rebuild from scratch – Signals that your startup is compounding organizational debt instead of improving actual outputThe 80/95 rule – Why “80% good in 3 months” often beats “95% perfect in 12” in hardtech and climate markets where timing matters--Join our confidential CEO community.Private CEO group for VC/PE-backed climate tech founders navigating capital, strategy, and scale.

Biomass waste is one of the largest unmanaged carbon flows, yet most climate solutions ignore it. This founder is turning landfills into carbon sinks using decentralized pyrolysis and biochar.Andrew Jones is the founder and CEO of Carba, a waste-to-value company converting biomass into permanent carbon removal. He studied catalytic fast pyrolysis and earned a PhD in chemical engineering from the University of California, Berkeley.Carba builds modular, decentralized systems that process biomass waste near aggregation points, producing biochar for landfill burial, methane reduction, and potential industrial uses.Here’s what we discussed:Site strategy that actually works – Targeting 10k–100k ton/year biomass hubs co-located with landfills to eliminate transport cost and preserve unit economicsLandfill use case, not theory – Biochar used as daily cover to (1) store carbon underground, (2) stimulate methanotrophs that oxidize methane, and (3) adsorb PFAS and other contaminantsReactor advantage – Custom molten-salt pyrolysis system vs rotary kilns, enabling tighter temperature control, higher carbon yield, and more consistent biochar quality at throughputCarbon permanence bet – Converting cellulose/lignin into stable aromatic carbon structures that resist microbial decay, especially in anaerobic landfill conditionsRevenue stack reality – Tipping fees exist but small; real upside is durable carbon credits, with optionality in steel, concrete, asphalt, tires, and filtration depending on local demand--Join our confidential CEO community.Private CEO group for VC/PE-backed climate tech founders navigating capital, strategy, and scale.

Vendor Financing Isn’t Free Money – Extending supplier payment terms can improve runway and reduce dilution, but concentrated climate supply chains create hidden dependency risk when critical vendors effectively become reluctant lenders.Working Capital Can Distort Reality – Better short-term cash metrics may hide structural fragility if supplier leverage, component concentration, or financing assumptions shift during tougher fundraising markets.The Leadership Bias That Damages Teams – Founders often misread underperformance as character failure instead of contextual pressure, creating avoidable trust breakdowns and weaker decision-making cultures.Empathy Still Requires Accountability – Understanding context matters, but repeatedly tolerating poor execution can quietly transfer the cost of one person’s struggles onto the broader organization.Why Great Operators Ask Better Questions – The strongest long-term partnerships in climate tech often come from listening well, speaking less, and focusing on genuine curiosity over transactional networking.--Join our confidential communityPrivate CEO group for VC/PE-backed climate tech founders navigating capital, strategy, and scale.

This 6x company founder and CEO explains how to structure smarter climate tech investment rounds and actually get renewable energy projects financed.Peter Davidson is CEO and founder of Aligned Climate Capital, a $2B AUM multi-strategy firm investing across venture and infrastructure. He previously led the U.S. Department of Energy Loan Programs Office and has founded or led six companies.Aligned focuses exclusively on low-carbon investments, with a core thesis that strong returns, not concessionary capital, will scale the energy transition.Here’s what we discussed:Capital strategy most founders miss – Second round should often be debt (bank, venture debt, DOE, green banks, vendor financing), not equity, to reduce dilution and extend runwayValuation is overrated – Partner quality, capital stack design, and working capital buffer matter more than headline priceOption pool trap – Negotiate “plussed up” pools to maintain ~5–10% through future rounds instead of getting diluted to zeroInfrastructure playbook – Buy NTP-ready community solar (3–10MW), build in 6–9 months, return ~70% capital via tax credits in ~3 years, then sell aggregated assets in years 6–7Market reality check – VC is constrained (few exits, fewer LP commitments), so founders must cut costs, accept lower valuations, or rethink viability--Join our confidential CEO communityPrivate CEO group for VC/PE-backed climate tech founders navigating capital, strategy, and scale.
