From grid monitoring to controlled burn robots.

Los Angeles has a long way to go before city and state officials can start looking for lessons to take away from these fires. Likely topics of discussion will include building resilient structures, vegetation management, and community preparedness. But there are also some more out of the box solutions coming from a growing number of technology companies — “firetech” startups, if you will — that are putting new, high-tech spins on some of these familiar solutions.
BurnBot, for instance, makes a remotely operated machine that executes efficient controlled burns to help mitigate wildfire risk. “I don't think you can ever replace the talent and the expertise and the know-how of the front line [firefighters],” Anukool Lakhina, CEO of BurnBot, told me this week. “But what you can do is make their job safer.”
Last August I wrote about Convective Capital, the venture capital firm exclusively focused on funding wildfire solutions, and one of its portfolio companies, Rhizome, which makes an AI-powered wildfire risk mitigation platform for utilities. Here are five more notable companies in Convective’s portfolio that will hopefully help bring wildfire prevention and mitigation into the future.
On January 8, as flames began to encircle Los Angeles, Gridware announced its $26.4 million Series A funding round. The company uses sensors placed on power poles to provide continuous monitoring of grid infrastructure and can alert grid operators to hazards and faults in realtime. This allows for rapid repairs and immediate response to wildfire threats such as equipment failure, downed lines, or any contact with vegetation. And because Gridware’s devices operate on solar power, they can remain online even during a power outage.
“Our country depends on the electric grid, yet until now, utilities have been operating it without reasonable monitoring capabilities,” said Bryan Schreier, a partner at Sequoia Capital, which led Gridware’s Series A, in a statement about the funding round. Utility-caused wildfires tend to be particularly damaging, as they often occur near populated areas. And though California utilities spend over $6 million annually on risk mitigation, most of that goes towards older technologies, something Gridware hopes to change.

Gridware implemented a successful pilot with PG&E last year, and has since expanded to monitoring over 1,000 miles of power lines for 18 different customers, with devices installed on about 10,000 poles.
As mentioned above, BurnBot deploys robots that can chop up vegetation and conduct controlled burns in a wide variety of geographies, from densely treed forests to shrubbery near urban environments. Traditionally, controlled burns are only safe to do in very particular weather conditions, but because BurnBot captures the smoke from its operations and immediately extinguishes the fires after vegetation is removed, Lakhina told me the robots can operate in all weather.
“Today, a lot of the predominant way that fuel treatment is done, regrettably, is extremely archaic. It's humans with matches setting things on fire, or humans with shovels and spades that go and dig the vegetation.” Some estimates calculate that the U.S. has about 200 million acres of land that need to be treated for wildfire risk, and “you're not going to get there relying only on humans or only on grazing,” Lakhina said. He estimates that the company’s robots can treat 40 times the area of a typical hand crew.
BurnBot has piloted its tech with CalFire, PG&E, and the U.S. Forest Service, and raised a $20 million Series A funding round last year.
Fire Aside makes software products that help fire departments and other safety agencies to digitize their inspections processes, thereby ensuring that homes and businesses are complying with fire safety requirements and helping to scale state and community wildfire prevention programs.
“It enhances the reach of municipal fire departments so that they can, at scale, communicate with their neighborhoods and their communities, and automate and digitize these inspections,” Jay Ribakove, principal at Convective Capital, told me. That’s certainly a step up from the traditional method, which involves “a firefighter showing up and leaving you with some handwritten notes on what you can do better,” Ribakove said. Residents in communities that use Fire Aside are five times more likely to take actions to protect their property against wildfire, the company says.
Fire Aside raised a seed round of undisclosed size in 2023, led by Convective Capital.
Early fire detection is one of the most critical factors in keeping blazes under control. Pano is a software company that relies on artificial intelligence and computer vision to automatically detect when and where a wildfire is breaking out. The company mounts its cameras on telecommunications towers, poles, or other equipment, which, combined with other inputs like satellite data, field sensors, and emergency alerts, gives fire professionals and first responders a unified view of any developing situation.
“The sooner that we can detect fires, the faster we can respond,” Ribakove told me, citing research that indicates that if wildfire response times in California were just 15 minutes quicker, the frequency of large, out-of-control fires could be reduced by at least 3% and as much as 7%. Given that California has experienced, on average, $117 billion in total annual economic losses from wildfires from 2017 to 2021, tech like Pano’s could save it as much as $8.2 billion per year.
Pano raised a $20 million Series A round in 2022 and a $17 million growth round in 2023.
Overstory has another approach to minimizing the presence of fire fuels, providing utilities with a “global vegetation management platform” that applies artificial intelligence to satellite imagery, allowing the company to identify the location, size, health, and species of any tree in the world. With this data, Overstory can then help utilities identify particular areas where vegetation might pose a wildfire risk, such as by growing too close to a power line, and recommend specific actions. Overstory also hopes its tech will save utilities money, as vegetation management budgets have ballooned in recent years.
Overstory works with more than 40 utilities, including PG&E, along with others in Canada, Brazil, and Europe. At the time of its $14 million Series A round, in 2023, the company said that it monitored about 2 million acres and protected about $6 billion in utility assets.

Heron Power and DG Matrix each score big funding rounds, plus news for heat pumps and sustainable fashion.
While industries with major administrative tailwinds such as nuclear and geothermal have been hogging the funding headlines lately, this week brings some variety with news featuring the unassuming but ever-powerful transformer. Two solid-state transformer startups just announced back-to-back funding rounds, promising to bring greater efficiency and smarter services to the grid and data centers alike. Throw in capital supporting heat pump adoption and a new fund for sustainable fashion, and it looks like a week for celebrating some of the quieter climate tech solutions.
Transformers are the silent workhorses of the energy transition. These often-underappreciated devices step up voltage for long-distance electricity transmission and step it back down so that it can be safely delivered to homes and businesses. As electrification accelerates and data centers race to come online, demand for transformers has surged — more than doubling since 2019 — creating a supply crunch in the U.S. that’s slowing the deployment of clean energy projects.
Against this backdrop, startup Heron Power just raised a $140 million Series B round co-led by Andreessen Horowitz and Breakthrough Energy Ventures to build next-generation solid state transformers. The company said its tech will be able to replace or consolidate much of today’s bulky transformer infrastructure, enabling electricity to move more efficiently between low-voltage technologies like solar, batteries, and data centers and medium-voltage grids. Heron’s transformers also promise greater control than conventional equipment, using power electronics and software to actively manage electricity flows, whereas traditional transformers are largely passive devices designed to change voltage.
This new funding will allow Heron to build a U.S.manufacturing facility designed to produce around 40 gigawatts of transformer equipment annually; it expects to begin production there next year. This latest raise follows quickly on the heels of its $38 million Series A round last May, reflecting hunger among customers for more efficient and quicker to deploy grid infrastructure solutions. Early announced customers include the clean energy developer Intersect Power and the data center developer Crusoe.
It’s a good time to be a transformer startup. DG Matrix, which also develops solid-state transformers, closed a $60 million Series A this week, led by Engine Ventures. The company plans to use the funding to scale its manufacturing and supply chain as it looks to supply data centers with its power-conversion systems.
Solid-state transformers — which use semiconductors to convert and control electricity — have been in the research and development phase for decades. Now they’re finally reaching the stage of technical maturity needed for commercial deployment, driving a surge in activity across the industry. DG Matrix’s emphasis is on creating flexible power conversion solutions, marketing its product as the world’s first “multi-port” solid-state transformer capable of managing and balancing electricity from multiple different sources at once.
“This Series A marks our transition from breakthrough technology to scaled infrastructure deployment,” Haroon Inam, DG Matrix’s CEO, said in a statement. “We are working with hyperscalers, energy companies, and industrial customers across North America and globally, with multiple gigawatt-class datacenters in the pipeline.” According to TechCrunch, data centers make up roughly 90% of DG Matrix’s current customer base, as its transformers can significantly reduce the space data centers require for power conversion.
Zero Homes, a digital platform and marketplace that helps homeowners manage the heat pump installation process, just announced a $16.8 million Series A round led by climate tech investor Prelude Ventures. The company’s free smartphone app lets customers create a “digital twin” of their home — a virtual model that mirrors the real-world version, built from photos, videos, and utility data. This allows homeowners to get quotes, purchase, and plan for their HVAC upgrade without the need for a traditional in-person inspection. The company says this will cut overall project costs by 20% on average.
Zero works with a network of vetted independent installers across the U.S., with active projects in California, Colorado, Massachusetts, Minnesota, and Illinois. As the startup plans for national expansion, it’s already gained traction with some local governments, partnering with Chicago on its Green Homes initiative and netting $745,000 from Colorado’s Office of Economic Development to grow its operations in Denver.
Climactic, an early-stage climate tech VC, launched a new hybrid fund called Material Scale, aimed at helping sustainable materials and apparel startups navigate the so-called “valley of death” — the gap between early-stage funding and the later-stage capital needed to commercialize. As Climactic’s cofounder Josh Fesler explained on LinkedIn, the fund is designed to cover the extra costs involved with sustainable production, bridging the gap between the market price of conventional materials and the higher price of sustainable materials.
Structured as a “hybrid debt-equity platform,” the fund allows Climactic’s investors to either take a traditional equity stake in materials startups or provide them with capital in the form of loans. TechCrunch reports that the fund’s initial investments will come from an $11 million special purpose vehicle, a separate entity created to fund a small set of initial investments that sits outside Material Scale’s main investing pool.
The fashion industry accounts for roughly 10% of global emissions. “These days there are many alt materials startups that have moved through science and structural risk, have venture funding, credible supply chains and most importantly can achieve market price and positive gross margins just with scale,” Fesler wrote in his LinkedIn post. “They just need the capital to grow into their rightful commercial place.”
Clean energy stocks were up after the court ruled that the president lacked legal authority to impose the trade barriers.
The Supreme Court struck down several of Donald Trump’s tariffs — the “fentanyl” tariffs on Canada, Mexico, and China and the worldwide “reciprocal” tariffs ostensibly designed to cure the trade deficit — on Friday morning, ruling that they are illegal under the International Emergency Economic Powers Act.
The actual details of refunding tariffs will have to be addressed by lower courts. Meanwhile, the White House has previewed plans to quickly reimpose tariffs under other, better-established authorities.
The tariffs have weighed heavily on clean energy manufacturers, with several companies’ share prices falling dramatically in the wake of the initial announcements in April and tariff discussion dominating subsequent earnings calls. Now there’s been a sigh of relief, although many analysts expected the Court to be extremely skeptical of the Trump administration’s legal arguments for the tariffs.
The iShares Global Clean Energy ETF was up almost 1%, and shares in the solar manufacturer First Solar and the inverter company Enphase were up over 5% and 3%, respectively.
First Solar initially seemed like a winner of the trade barriers, however the company said during its first quarter earnings call last year that the high tariff rate and uncertainty about future policy negatively affected investments it had made in Asia for the U.S. market. Enphase, the inverter and battery company, reported that its gross margins included five percentage points of negative impact from reciprocal tariffs.
Trump unveiled the reciprocal tariffs on April 2, a.k.a. “liberation day,” and they have dominated decisionmaking and investor sentiment for clean energy companies. Despite extensive efforts to build an American supply chain, many U.S. clean energy companies — especially if they deal with batteries or solar — are still often dependent on imports, especially from Asia and specifically China.
In an April earnings call, Tesla’s chief financial officer said that the impact of tariffs on the company’s energy business would be “outsized.” The turbine manufacturer GE Vernova predicted hundreds of millions of dollars of new costs.
Companies scrambled and accelerated their efforts to source products and supplies from the United States, or at least anywhere other than China.
Even though the tariffs were quickly dialed back following a brutal market reaction, costs that were still being felt through the end of last year. Tesla said during its January earnings call that it expected margins to shrink in its energy business due to “policy uncertainty” and the “cost of tariffs.”
Current conditions: More than a foot of snow is blanketing the California mountains • With thousands already displaced by flooding, Papua New Guinea is facing more days of thunderstorms ahead • It’s snowing in Ulaanbaatar today, and temperatures in the Mongolian capital will plunge from 31 degrees Fahrenheit to as low as 2 degrees by Sunday.
We all know the truisms of market logic 101. Precious metals surge when political volatility threatens economic instability. Gun stocks pop when a mass shooting stirs calls for firearm restrictions. And — as anyone who’s been paying attention to the world over the past year knows — oil prices spike when war with Iran looks imminent. Sure enough, the price of crude hit a six-month high Wednesday before inching upward still on Thursday after President Donald Trump publicly gave Tehran 10 to 15 days to agree to a peace deal or face “bad things.” Despite the largest U.S. troop buildup in the Middle East since 2003, the American military action won’t feature a ground invasion, said Gregory Brew, the Eurasia Group analyst who tracks Iran and energy issues. “It will be air strikes, possibly commando raids,” he wrote Thursday in a series of posts on X. Comparisons to Iraq “miss the mark,” he said, because whatever Trump does will likely wrap up in days. The bigger issue is that the conflict likely won’t resolve any of the issues that make Iran such a flashpoint. “There will be no deal, the regime will still be there, the missile and nuclear programs will remain and will be slowly rebuilt,” Brew wrote. “In six months, we could be back in the same situation.”
California, Colorado, and Washington led 10 other states in suing the Trump administration this week over the Department of Energy’s termination of billions in federal funding for clean energy and infrastructure projects. In a lawsuit filed in federal court in San Francisco, the states accuse the agency of using a “nebulous and opaque” review process to justify slashing billions in funding that was already awarded. “These aren’t optional programs — these are investments approved by bipartisan majorities in Congress,” California Attorney General Rob Bonta said at a press conference announcing the lawsuit, according to Courthouse News Service. “The president doesn’t get to cancel them simply because he disagrees with them. California won’t allow President Trump and his administration to play politics with our economy, our energy grid and our jobs.”

If you’re looking for a sign of the coming geothermal energy boom in the U.S., consider this: There is now a double-digit number of next-generation projects underway, according to an overview the Energy Information Administration published Thursday. For the past century, geothermal energy has relied upon finding and tapping into suitably hot underground reservoirs of water. But a new generation of “enhanced” geothermal companies is using modern drilling techniques to harness heat from dry rocks.

If you’re looking for a thorough overview of the technology, Heatmap’s Matthew Zeitlin wrote the definitive 101 explainer here. But a few represent some of the earliest experiments in enhanced geothermal, including the Fenton Hill in New Mexico, established in the 1970s, which was the world’s first successful project to use the technology.

When Exxon Mobil announced plans in December to scale back its spending on low-carbon investments, the oil giant justified the move in part on all the carbon capture and storage projects poised to come online this year that would vault the company ahead of its rivals. This week, Exxon Mobil started transporting and storing captured carbon dioxide at its latest facility in Louisiana. The New Generation Gas Gathering facility on the western edge of the state’s Gulf Coast is the company’s second CCS project in Louisiana. Known as NG3, the project is set to remove 1.2 million tons of CO2 per year from gas streams headed to export markets on the coast. The Carbon Herald reported that two additional CCS projects are set to start up operations this year.
CCS got a big boost in October when Google agreed to back construction of a gas-fired power plant built with carbon capture tech from the ground up. The plant, which Matthew noted at the time would be the first of its kind at a commercial scale, is sited near a well where captured carbon can be injected. Senate Democrats, meanwhile, are reportedly probing the Trump administration’s decision to redirect CCS funding to coal plants.
In 2019, Maine expanded its Net Energy Billing program to subsidize construction of commercial-scale solar farms across the state. “And it worked,” Maine Public Radio reported last July when the state passed a law to phase out the funding, “too well, some argue.” In 2025 alone, ratepayers in the state were on the hook for $234 million to support the program. Solar companies sued, arguing that the abrupt cut to state support had unfairly deprived them of funding. But this week U.S. District Judge Stacey Neumann denied a motion the owners of dozens of solar farms filed requesting an injunction.
That isn’t to say things aren’t looking sunny for solar in Maine. On the contrary, just yesterday the developer Swift Current Energy secured $248 million in project financing for a 122-megawatt solar farm and the Poland Spring water company went on statewide TV to show off the new panels on its bottling plant. The federal outlook isn’t as bright at the moment. As Heatmap’s Jael Holzman reported in December, the solar industry was begging Congress for help to end the Trump administration’s permitting blockade on new projects on federal lands.
The Trump-stumping country music star John Rich is continuing his crusade against the Tennessee Valley Authority. Months after blocking construction of a gas plant in his neighborhood, Rich personally pressed TVA CEO Don Moul to reroute a transmission line, posting a video Thursday of farmers who opposed the federal utility’s use of the right of way process to push through the project. Rich said Moul “personally told me as of this morning” TVA will put the effort on hold. The left-wing energy writer and Heatmap contributor Fred Stafford summed it up this way on X: “MAGA NIMBY rises, Dark Abundance falls. TVA ratepayers will be paying more for a rerouted transmission project because this country music star threw his support behind a local farmer who refuses to allow the transmission line to cross his land.”
