The climate tech IPO window could finally be cracking open

Climate tech startups are capital intensive, timelines are long, and the technology is often considered “first of its kind.” What’s more, a key value proposition is addressing pollution — an externality that is, at best, poorly priced by the market. Those aren’t the qualities stock pickers tend to favor.

And yet, public markets appear to be warming to climate tech startups — or at least some of them.

This week, nuclear startup X-energy went public, raising $1 billion in an upsized share offering that appears to have delivered a windfall for its investors, including Amazon. Retail investors apparently can’t get enough, with the stock popping 25% in its first hour of trading. Also this week, geothermal startup Fervo said it filed for an initial public offering. The size of the Fervo IPO has yet to be disclosed, but private investors have valued the company at around $3 billion, according to PitchBook.

The move to go public aligns with what investors told TechCrunch at the end of last year. After years of tepid attitudes toward climate tech companies, they expected public markets to start welcoming energy-related startups. Nearly every investor that weighed in on the question said the startups with the best chances of going public specialize in either nuclear fission or enhanced geothermal. Fervo, specifically, was mentioned several times.

Thank data centers for that. The AI craze has taken a trend of rising demand for electricity and made it sexy and salable. Companies that were already betting on the upswing lucked into a trending narrative that coincided with their technological maturity. Fortune certainly favors the prepared. 

The IPOs are also certain to please investors, letting them return capital to their LPs. The recent dearth of IPOs has kept a chunk of climate tech funding locked up, at a time when many funds would like to start cashing out.

But it’s not just about cashing out.

Fervo and X-energy have followed the traditional route to public markets, suggesting there is confidence that a broad base of investors wants to participate. If it were just about freeing up investor capital, the startups could have followed the SPAC route. (Several have.) But these two companies took the longer path.

Yet for all that success, a wide swathe of climate tech will probably be left out of the IPO wave.

Companies that aren’t entangled in energy markets will have to find other ways to press on — and without access to the deep pockets the public market provides. The divergence suggests the climate tech world is starting to go K-shaped, a trend which Mark Cupta, managing director at Prelude Ventures, suggested when I spoke to him a little over a week ago.

Companies stuck on the poorer side of the IPO window still have private investors to lean on. But there, too, a K-shaped trajectory is starting to appear.

Venture capital and growth funds raised about $6.5 billion last year, according to Sightline Climate. That’s the same as in 2021, but because there are more funds today, each fund is now smaller. For founders, that could be bad news since funds have less to draw on. On the upside, more competition could drive better fundraising results.

At the same time, the big funds keep getting bigger. Infrastructure dominated climate tech fundraising last year, with 42 funds raising 75% of all dollars in the sector, according to Sightline Climate. That success will spill over into the startup side if it’s a company with a mature technology that is ready to build big. 

Sightline said that many new infrastructure funds are specializing in renewables, grid technologies, and energy storage. In other words, the K-shape isn’t going away anytime soon.

ElevenLabs lists BlackRock, Jamie Foxx, and Eva Longoria as new investors

Voice AI company ElevenLabs revealed new investors that are part of its $500 million Series D fundraise, which was first announced in February. The additions include institutions such as BlackRock, Wellington, D.E. Shaw, and Schroders; enterprises like Nvidia, Salesforce Ventures, Santander, KPN, and Deutsche Telekom; and individual investors such as Jamie Foxx, Eva Longoria, and Squid Game creator Hwang Dong-hyuk.

The startup also noted that it surpassed $500 million in ARR (annual recurring revenue), after ending last year with nearly $350 million in ARR. The company’s co-founder and CEO, Mati Staniszewski, said last month that ElevenLabs added $100 million in net new ARR in Q1 2026, ending the quarter at roughly $450 million in ARR.

The company has also accelerated its valuation rapidly, growing from $6.6 billion last September to $11 billion this February.

“Voice is the highest-stakes channel for any customer interaction, and the bar for quality, latency, and security is extremely high. ElevenLabs is not just a category leader – it is becoming a foundational enabler of Deutsche Telekom’s broader Industrial AI vision. From voice-as-a-service to multilingual automation and in-network AI agents, we believe the company is uniquely positioned to reshape how businesses interact with customers across all channels,” Karine Peters, managing director at Deutsche Telekom’s venture arm T.Capital, said in a statement.

In the past quarter, the voice AI company has signed enterprise contracts with the likes of Deutsche Telekom, Revolut, and Klarna.

ElevenLabs said that, besides the fundraising, it also closed a $100 million tender, a second in roughly six months after the company issued one last September. Staniszewski said in a blog post that the company will give an opportunity to retail investors to invest in ElevenLabs through Robinhood Ventures, but didn’t provide details about the program.

Staniszewski noted that consumers won’t trust systems that sound robotic or “interact strangely” and emphasized the importance of building “human-level AI voice models.” Last month, the company acquired the team from Polish voice AI startup Papla to bolster its research team.

Kaspersky suspects Chinese hackers planted a backdoor into Daemon Tools in ‘widespread’ attack

Security researchers at Kaspersky say they have identified a malicious backdoor planted in the popular and long-running Windows disc imaging software, Daemon Tools. 

The Russian cybersecurity company said on Tuesday that data collected from computers around the world running the Kaspersky antivirus software shows a “widespread” attack is under way, targeting thousands of Windows computers running Daemon Tools.

The hackers, whom Kaspersky has linked to a Chinese-language speaking group based on an analysis of the malware, used the backdoor in Daemon Tools to plant additional malware on a dozen computers across the retail, scientific and manufacturing sectors, as well as government systems. Kaspersky said the hacking of these specific computers implied a “targeted” effort. 

The company said the targeted organizations are located in Russia, Belarus, and Thailand.

Kaspersky said the backdoor was first detected on April 8.

Kaspersky said it had contacted Disc Soft, the company that maintains Daemon Tools, but did not say if the developer responded or took action. Kaspersky said the supply chain attack is “still active,” suggesting that the hackers can still plant malware on thousands of computers running the disc imaging software.

This is the latest in a string of so-called “supply chain” attacks that have targeted developers of popular software in recent months. Hackers are increasingly taking aim at the accounts of developers who work on widely used code and software, and abusing that access to push malicious code to anyone who relies on the software. This approach lets the hackers break into a large number of computers at once when their malicious code is delivered as a software update.

Earlier this year, hackers associated with the Chinese government hijacked the popular text editing software Notepad++ to deliver malware to a number of organizations with interests in East Asia. Security researchers also warned of another attack last month targeting users who visited the website of CPUID, which makes the popular HWMonitor and CPU-Z tools.

TechCrunch downloaded the Windows installer from Daemon Tools’ website, and the file appeared to contain the backdoor when we checked it with the online malware scanner service VirusTotal.

It’s not known if the macOS version of Daemon Tools was compromised, or if other apps made by Disc Soft are affected.

When contacted for comment, a Disc Soft representative said they are “aware of the report and are currently investigating the situation.”

“Our team is treating this matter with the highest priority and is actively working to assess and address the issue. At this stage, we are not in a position to confirm specific details referenced in the report. However, we are taking all necessary steps to remediate any potential risks and to ensure the security of our users,” the representative said.

Etsy launches its app within ChatGPT as it continues its AI push

Etsy announced Tuesday the launch of its native app within ChatGPT, opening up a new way for shoppers to explore its catalog of over 100 million listings.

The new experience is designed to move beyond the limitations of traditional keyword queries. Instead of typing something like “wooden coffee table,” then scrolling and adjusting filters, users can now express what they’re looking for in natural language. For instance, “Help me find a Mother’s Day gift under $100 for my mom who loves gardening.”

Now live in beta, the feature allows users to tag @Etsy directly within a prompt. From there, the Etsy app in ChatGPT surfaces relevant product listings that users can browse, compare, and click through to Etsy for additional details or purchase.

This isn’t Etsy’s first experiment inside ChatGPT. Back in September, Etsy became an early partner in ChatGPT’s Instant Checkout integration, which let users buy products directly inside the chat interface. However, the initiative ended in March, suggesting it didn’t perform as OpenAI had hoped. It was reported that Etsy didn’t see a large volume of sales from the integration, leading Etsy to start building a native app within ChatGPT instead. 

Alongside this launch, Etsy also revealed it’s testing a beta conversational search experience within its platform, specifically geared toward helping users find gifts. The gift assistant acts as a personal shopper, offering a guided, conversational way to discover ideas, narrow down preferences, and surface relevant products.

This builds on Etsy’s broader AI push, which includes an AI-powered discovery experience featuring curated collections and a suite of seller tools, including a tool that helps generate product titles and descriptions, as well as a writing assistant to help draft messages to buyers. In 2024, Etsy introduced a new “Designed” label to identify AI content, part of an effort to increase transparency as AI-generated artwork becomes more prevalent on the platform.

The news of a ChatGPT integration comes a week after Etsy reported its Q1 2026 earnings, surpassing revenue expectations with $631 million, and marketplace gross merchandise sales were up 6% year over year. Notably, active buyers increased for the first time in two years to 86.6 million. Etsy also touted 5.6 million active sellers on the platform. 

In February, the company announced it was selling Depop to eBay for $1.2 billion in cash, a move aimed at doubling down on its core marketplace.

Etsy joins a growing list of companies building native apps within ChatGPT, including Angi, SeatGeek, Tubi, and Wix. Developers have been able to build apps within the chatbot since October.
