Climate CEOs

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 cooking

• Multifamily 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 appliances

• Appliances 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 costs

• Licensing instead of building everything alone – Copper is pursuing partnerships with incumbent appliance manufacturers rather than vertically integrating every product category itself

• Founder 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

Women founders receive just 2–3% of venture capital. So why do they consistently outperform on capital efficiency, revenue generation, and exits?

Six climate tech leaders share the hard-earned tactics they use to navigate bias, build authority, and scale companies in an ecosystem that still underfunds women entrepreneurs.

This episode draws lessons from six women EFI Climate CEO Fellows and Mentors, including founders, operators, investors, and nonprofit leaders who have raised over $100M, built and exited private-equity-backed companies, secured billion-dollar commercial agreements, and led organizations representing hundreds of thousands of professionals.

• Pre-selling authority — using LinkedIn, podcasts, and public presence so credibility enters the room first
• Owning the first 60 seconds — naming your role and credentials before others define you
• Using silence as leverage — responding to bias without over-explaining or softening
• Diligencing investors — reference-checking failed portfolio founders, not just winners
• Scaling beyond expertise — moving from technical expert to strategic architect with stronger hires and allies

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 matters

Most 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.

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 work
• Lead with the risks – Founders who proactively surface weaknesses build trust faster than those who hide them
• Desperation is visible – Targeted fundraising and calm execution outperform broad outreach and forced urgency

The $1T Industrial Heat Problem Most Startups Underestimate | Tempo

Industrial 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 barriers
• Design for logistics first – Shipping, installation, and transport constraints often determine scalability more than technology performance
• Start with narrow deployments – One successful plant can become the proof point that unlocks broader adoption

This limestone battery can achieve 100+ hour heat storage without lithium and zero standby losses.

Industrial heat is a $1T+ problem, but most solutions ignore storage, especially those using ancient chemistry.

Arpit Dwivedi is the founder and CEO of Cache Energy, building thermal storage systems for industrial decarbonization.

Cache uses calcium oxide chemistry to store and release heat, targeting sub-1,000°F processes that represent ~75% of global industrial demand, with modular systems designed for rapid deployment and low cost.

Here’s what we discussed:

• Unit economics anchored in materials, not breakthroughs – Limestone feedstock at <$500/ton, 95% off-the-shelf hardware, and a small proprietary binder that enables pellet durability and repeat cycling without degradation typical of lime powders

• Operational performance that mimics baseload fuel – 100+ hour discharge with effectively zero standby losses over 6–9 months, allowing customers to arbitrage cheap off-peak electricity into constant, gas-like heat output

• Deployment speed as wedge – Containerized 2MW systems installed and operational within hours (e.g., University of Minnesota), eliminating long EPC timelines and specialized on-site labor

• Proven industrial ROI, not pilots – Single-process retrofit at a Fortune 500 Midwest manufacturer reduced natural gas consumption ~98%, with expansion to additional plants based on measured performance

• Financing unlocks adoption – Leasing model with flat monthly pricing, uptime guarantees, and full O&M removes capex friction while enabling transition to $150–200M project finance-backed scaling

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 project
• Opportunity overload – How “adjacencies” like new geographies, EV charging, or development capital can become strategic debt instead of growth
• Focus as competitive advantage – Why the best operators often win by doing fewer things deeper while competitors chase every inbound request
• When to rebuild from scratch – Signals that your startup is compounding organizational debt instead of improving actual output
• The 80/95 rule – Why “80% good in 3 months” often beats “95% perfect in 12” in hardtech and climate markets where timing matters

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 economics

• Landfill 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 contaminants

• Reactor advantage – Custom molten-salt pyrolysis system vs rotary kilns, enabling tighter temperature control, higher carbon yield, and more consistent biochar quality at throughput

• Carbon permanence bet – Converting cellulose/lignin into stable aromatic carbon structures that resist microbial decay, especially in anaerobic landfill conditions

• Revenue 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

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.

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 runway

• Valuation is overrated – Partner quality, capital stack design, and working capital buffer matter more than headline price

• Option pool trap – Negotiate “plussed up” pools to maintain ~5–10% through future rounds instead of getting diluted to zero

• Infrastructure 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 6–7

• Market reality check – VC is constrained (few exits, fewer LP commitments), so founders must cut costs, accept lower valuations, or rethink viability

Three decisions that determine if climate tech founders scale or stall: Customer focus, sustainable intensity, and information diet all compound into capital efficiency and judgment.

• Antelope vs mice – Why chasing small, fast customers can accelerate learning but trap you in low-value revenue, while large customers require patience but define the business
• GTM timing – Matching customer type to runway and product maturity, not just who says yes first
• Stagnation vs safety – Why constant urgency degrades judgment and burns teams, especially in capital-intensive climate startups
• Sustainable intensity – Protecting thinking time as a core CEO function, not a luxury, to avoid reactive decision-making
• News vs history – How overconsuming short-term signals creates bias, while historical pattern recognition sharpens long-term strategy
