A grab bag of funded startups caught our attention this past month, from a previously bootstrapped custom metal manufacturer that got its first outside funding from big-name Silicon Valley backers, to a startup that aims to provide geothermal energy from underwater volcanoes to small island nations. Let鈥檚 take a look.

$110M for on-demand custom manufacturing

First, let鈥檚 start with a refreshingly non-AI round, and a sizable one at that.

Reno, Nevada-based said last month that it has raised $110 million in funding led by brothers and founders and , along with and , at a $1 billion valuation.

The company operates an on-demand manufacturing platform specializing in custom-cut metal and fabrication. The round is its first venture investment, and apparently came only after Sequoia’s flew to Reno to woo SendCutSend CEO into accepting Silicon Valley backing. Previously, Belosic had bootstrapped the company, founded in 2018, with personal savings, bank loans and credit cards, he told .

He held little interest in taking cash from startup investors until SendCutSend started to be flooded earlier this year with orders from AI-driven industries including robotics and data centers, and Belosic said he realized the business needed outside investment to grow.

Investor of Paradigm told WSJ that underlying SendCutSend鈥檚 booming business is intense demand for rapid, on-demand sheet metal and custom parts. 鈥淚f you think about the entire frontier of robots, defense companies, rocket companies, electric-car companies, they all need very fast turn prototyping,鈥� he said.

The investment is Paradigm鈥檚 first into the manufacturing sector, he noted.

$100M for insurance-covered metabolic health counseling

GLP-1 weight-loss drugs may be booming, but a well-funded startup is betting that medication alone isn鈥檛 enough to solve the chronic disease crisis.

, a New York-based metabolic health startup that combines dietitians, AI tools and GLP-1 medication management, last month said that it raised a $100 million Series C round led by . , , and a long list of other investors also backed the round, which brings the company鈥檚 total funding to date to just over $213 million, .

Founded in 2021, Nourish operates what it describes as the country鈥檚 largest dietitian-led metabolic health clinic, pairing more than 10,000 registered dietitians with AI coaching, lab testing and virtual care. The company has increasingly expanded into GLP-1 prescribing and medication management as demand for drugs such as Ozempic and Wegovy continues to surge.

Nourish said it has partnered with hundreds of health insurers in the U.S. and that its service is covered by most plans.

Its pitch is that the next phase of the GLP-1 boom will require more than prescriptions. While the drugs have transformed obesity treatment, many patients struggle to stay on them long term or maintain results after stopping, according to the company. Nourish is positioning itself as a broader metabolic health platform focused on nutrition, behavior change and ongoing clinical support alongside medication.

鈥淐hronic disease is the central failure of U.S. healthcare 鈥� nearly 200 million Americans affected, trillions spent, and outcomes that still don’t move,鈥� Menlo Ventures partner said in a statement. 鈥淲hat Nourish has built in four years is remarkable: a care model that actually bends the cost curve, with 10,000 dietitians, deep payer relationships, and clinical outcomes patients stick with.鈥�

$58M for Gen Z group travel adventures

Group travel startups are having a moment as younger travelers increasingly look for ways to meet people while exploring new destinations.

, a Milan-based startup that organizes group travel experiences for millennials and Gen Z travelers, raised a 鈧�50 million (roughly $58 million) Series C funding round as it looks to expand further across Europe and enter the U.S. market. The round was led by .

Founded in 2017, WeRoad operates a platform that connects solo travelers and small groups through curated multiday trips led by coordinators. The company says it has served more than 300,000 travelers across over 1,000 itineraries, with offerings ranging from adventure travel and cultural experiences to outdoor excursions. Participants are typically grouped with strangers in similar age ranges, turning the trips into a hybrid of travel booking and social networking.

$26M to keep AI data centers cooler

AI may be driving the data center boom, but keeping those facilities cool is becoming a business opportunity in its own right.

, a U.K.-based startup developing precision liquid cooling systems for AI infrastructure, said last month that it raised a $26 million Series B as demand surges for technologies that can manage the growing heat and power requirements of next-generation AI data centers. The round was led by and and brings Iceotope鈥檚 total funding to date to just under $100 million, .

Founded in 2005, Iceotope has developed a chassis-based liquid cooling approach designed to replace traditional air cooling and cool entire systems rather than individual chips. The company says it now holds 219 granted and pending patents. It said it will use the new funding to expand product and engineering development, grow its patent portfolio and accelerate partnerships that bring its cooling technology to market.

The raise comes as AI workloads create mounting challenges for conventional cooling systems. Iceotope argues its technology can reduce energy consumption and water use while supporting high-density AI and high-performance computing deployments in both data centers and edge environments.

$25M for geothermal energy from subsea volcanoes

As AI companies scramble for more electricity, investors are increasingly willing to fund some unconventional ideas for generating it. One of those is , a Seattle-based startup developing subsea geothermal power systems designed to tap into heat generated by subsea volcanic activity.

The company recently raised between $25 million and $30 million in a seed round led by , sources familiar with the matter .

Founded just last year, Endurance Energy is targeting island nations 鈥� where it says electricity can cost almost 7x as much as in the U.S. 鈥� industrial sites and eventually hyperscale data centers that need large amounts of reliable power.

Unlike solar and wind, geothermal energy carries the promise of round-the-clock, renewable baseload electricity, a feature that has become increasingly attractive as AI infrastructure drives soaring power demand.

Endurance says its seafloor geothermal generators could deliver gigawatts of power from hydrothermal systems along tectonic plate boundaries and volcanic regions. It is , where about 80% of electricity generation still relies on imported diesel fuel.

Earlier this year, the company signed an agreement with the Tongan government and launched a pilot project aimed at harnessing geothermal heat generated by subsea volcanic activity around the island nation.

鈥淐lean geothermal power will enable us to substitute most of our diesel base load power and further insulate ourselves from future external shocks caused by geopolitical conflicts and global economic impacts,鈥� Tongan Prime Minister Lord Fakaf膩nua said in a statement.

How times have changed. Already this year, more than $14.6 billion in venture investment has gone into companies in 颁谤耻苍肠丑产补蝉别鈥檚 military, national security and law enforcement categories, blowing past the sector’s previous annual record of $9.6 billion raised in all of 2025.

Investors have poured billions into startups developing AI-powered military systems, autonomous vehicles, defense software and space technologies, and they’re writing increasingly large checks to do it, 小蓝视频色情网页版 data shows.

Funding growth accelerates

The defense tech sector’s rise has been years in the making

Global defense tech funding totaled $1.6 billion in 2020 before climbing to $3.9 billion in 2021, 小蓝视频色情网页版 data shows. Funding then remained relatively steady between roughly $2.8 billion and $3.8 billion from 2022 through 2024.

That changed dramatically last year, when funding jumped to a record $9.6 billion. Now, five months into 2026, startups in the sector have already eclipsed the full-year record set in 2025.

Deal flow has stayed steadier, mirroring a broader trend of venture capital concentration. So far this year, defense tech startups have announced 107 venture rounds, 小蓝视频色情网页版 data shows, putting 2026鈥檚 pace slightly ahead of the 206 deals done in 2025.

Megarounds lead the way

The biggest contributor to this year’s funding surge, by far, is .

The Costa Mesa, California-based company announced a $5 billion Series H last month, a deal that valued it at $30.5 billion and further cemented its status as the most valuable venture-backed defense startup in the world.

Still, it鈥檚 not the only defense- or military-related startup drawing large sums of funding. Many of this year’s biggest rounds involve companies building AI-enabled defense systems, autonomous aircraft and maritime vehicles, military software platforms and space infrastructure.

Case in point: a $300 million Series C round announced today for , an autonomous drones systems manufacturer. The round was led by and and values the Huntington Beach, California-based startup at $1.8 billion.

Autonomous aviation startup raised a $2 billion Series G round in March led by and, while , which makes unmanned surface vessels for naval and defense use, secured a $1.75 billion Series D led by later that month.

Space-related startups with defense applications have also been especially prominent among defense-tech bets this year. , and , rank among the largest defense-related funding recipients of 2026, highlighting continued investor interest in technologies with both commercial and national security applications.

Attention turns to exits

As funding totals climb, investors may begin looking toward exits. Already this year, one smaller defense-tech startup, AI drone company , went public, with shares soaring more than 500% in their first day of trading. They remain near the high end of their price range as of early June.

Anduril is now widely viewed as one of the most likely defense tech candidates to pursue an IPO in the coming years. A public offering by a company of its size would mark a significant milestone for the sector and provide a closely watched test of public-market appetite for next-generation defense contractors.

Other well-capitalized companies across defense, autonomy and space are also reaching a scale where public listings or major acquisitions become more plausible, with 颁谤耻苍肠丑产补蝉别鈥檚 predictive intelligence tools forecasting that nearly four-dozen . Along with Anduril, they include True Anomaly, Shield AI, Sierra Space and .

$60M for a legal tech operating system

Legal tech has been one of the fastest-growing startup sectors in recent years, at least when measured by funding to the area, with venture investors pouring a record $4 billion-plus into the industry last year. That growth, of course, has been driven by AI鈥檚 rapid automation of many aspects of the notoriously paperwork-heavy industry.

Adding to this year’s tally is , a startup that says it鈥檚 building the operating system and brand for AI-native law firms. The startup said last month that it raised $60 million in Series A funding at a $750 million valuation from big-name investors. led the round and , and participated.

Manifest OS says it takes a different tack than most legal tech startups. Rather than sell software to traditional law firms that operate under a billable hour model, the company only caters to AI-native firms that charge clients based on outcomes.

鈥淐ompanies want fee transparency, predictability, and speed,鈥� , a Manifest investor and former general counsel for 听1, and , said in a statement. 鈥淟awyers want to focus on delivering results, not justifying billable hours.

Along with AI software that helps attorneys with tasks like client communications, legal research, document drafting and billing, Manifest OS also offers a centralized back office to handle client intake, business development, paralegal work and other administrative tasks. That, according to the firm, frees attorneys up to focus on more complex legal work.

One important caveat: All firms that use its platform operate under the Manifest Law name. According to the startup, that results in a consistent brand presence, pricing, response time and service quality to clients. Its is a business immigration law firm.

The startup says it has already served 150-plus corporate clients, including large tech companies, since launching 18 months earlier. It has hired more than 100 attorneys to date, it said, less than 1% of those that applied.

$23M for industrial solar panel recycling

French cleantech startup said last month that it has secured 鈧�20 million (about $23 million) in Series B and grant funding to tackle a growing problem: industrial-scale solar panel recycling.听

By 2050, tens of millions of tons of solar panels are expected to become defunct, according to ROSI. The company鈥檚 technology recovers high-purity raw materials including silver, silicon, copper, aluminum and glass from those panels so that they can be recycled into new products.听

Last quarter, a handful of large, well-funded AI companies, almost all based in the U.S., captured the vast majority of venture dollars, even as global startup deal count fell.

AI takes 80% of global venture funding

AI startups for the first time captured half of global venture funding in Q4 2024. Since then, that percentage has hovered around 50% 鈥� until Q1 of this year, when 鈥檚 record-setting round, along with a small handful of other enormous deals, pushed AI鈥檚 share to 80% of the quarterly funding total.

Top 4 vs. everyone else

It wasn鈥檛 just that AI as an industry captured the lion鈥檚 share of venture funding last quarter. Just four companies took nearly two-thirds of the entire pie, 小蓝视频色情网页版 data shows.

Four of the five largest venture rounds ever recorded were closed in Q1 2026, with frontier labs OpenAI ($122 billion), ($30 billion), ($20 billion) and self-driving company ($16 billion) collectively raising $188 billion, or nearly 65% of global venture investment in the quarter.

Deal count falls even as dollars surge

And while last quarter set an all-time record for venture dollars invested, more money went to fewer companies, continuing an overall downward trend for deal count we鈥檝e seen since the beginning of 2021.

That was the case not just in North America, where dollars invested surged 190% year over year, even as deal count dropped 26%. It also held true in Europe and Latin America. Only Asia saw a modest 5% bump in deal count along with more dollars invested.

Methodology

We tracked the largest announced rounds in the 小蓝视频色情网页版 database that were raised by U.S.-based companies for the period of April 4-10. Although most announced rounds are represented in the database, there could be a small time lag as some rounds are reported late in the week.

In a quarter when nearly two-thirds of global venture capital went to just four companies, it鈥檚 easy to lose track of the many other companies getting funding to tackle interesting problems. Nonetheless, we spotted five companies in just the past month working on issues from cleaner ferries and trains to foundational AI for plants. Let鈥檚 take a closer look.

$55M for a mineral rights-backed credit card

Natural resources can be incredibly valuable financial assets, but you can鈥檛 exactly buy your weekly groceries with oil or water rights.

That鈥檚 an issue that a Dallas-based fintech startup aims to solve. recently raised $50 million in a debt round from to provide a credit card to U.S. households holding mineral rights to natural resources such as oil, natural gas, solar, wind or water.

鈥淔or the millions of mineral rights owners in the United States, these rights are one of the most valuable assets the family owns. But these families are just like the rest of Americans and often are carrying revolving credit card balances at more than 25% [interest],鈥� Frontlands CEO said in a statement. 鈥淗istorically, owners have had few options to access the value trapped inside their mineral rights without selling.鈥�

Its AI system combines machine learning, production data, royalty payment histories, lease terms, commodity price forecasts, geologic data and traditional to automate the underwriting process, the company says. While it鈥檚 historically been difficult for traditional lenders to assess natural resources as collateral, Frontlands says its process typically delivers a same-day credit decision.

The company鈥檚 recent credit facility is in addition to a announced in December from venture investors including , , and .

Frontlands said its average credit line in early markets 鈥� Texas, Pennsylvania, New Mexico, North Dakota, Wyoming and Oklahoma 鈥� is more than $30,000. It plans to launch its credit card product this summer in partnership with Texas-based sponsor bank .

Frontlands said it also expects to raise a Series A round later this year.

鈥淥ur goal isn鈥檛 to pile on more debt,鈥� Cotter said in a statement. 鈥淏ut the opportunity to help our customers move away from high-interest credit card debt 鈥� and provide a path toward greater financial stability 鈥� is compelling.鈥�

Investment in fintech startups hit a multiyear high in 2025, 小蓝视频色情网页版 data shows, though remains well below the peak. Many of the best-funded companies in recent quarters have brought AI to bear on traditionally more manual or cumbersome processes in the financial services industry.

$32M for 鈥榝lying鈥� electric commuter ferries

As of this writing, oil prices are hovering around $100 a barrel 鈥� down from an even greater peak a few weeks earlier, but still among the highest levels seen in years, as the U.S.-Iran war disrupts global energy markets.

So Swedish electric vessel maker 鈥檚 recent funding of 鈧�30 million (about $32 million) seems timely. The Stockholm-based company makes electric 鈥渇lying鈥� boats that are used as commuter ferries. They differ from traditional vessels by using computer-controlled hydrofoils to lift the hull above the water, an approach the company says dramatically reduces drag and cuts energy use by up to 80% 鈥� enabling faster, smoother, zero-emission travel compared to conventional diesel ferries that push through the water.

鈥淔rom a physics perspective, ships have been essentially the same for hundreds of years,鈥� Candela founder and CEO said in a statement. 鈥淲e’re redefining waterborne transport by effectively creating a new category of vessel. This allows cities and municipalities to finally take full advantage of waterways 鈥� while escaping the fossil-fuel cost trap that has long prevented them from being used efficiently.鈥�

Its P-12 vessels have already been deployed as commuter ferries in Stockholm, Gothenburg, Oslo and Trondheim.

The new funding was led by 鈥檚 arm and included previous investors , , and .

The capital will primarily be used to fund a second factory in Poland. Candela says it has more than 65 vessels on order and planned deployments across markets including India 鈥� where a fleet of 10 of its P-12s will reportedly cut travel times from Navi Mumbai Airport to the city center from around two hours to 35 minutes 鈥斕齮he Middle East and Southeast Asia.

The startup鈥檚 funding defies an overall downturn in clean-tech funding. Funding for clean-tech related startups totaled $26.9 billion in 2025, down 23% year over year and the lowest annual amount since 2020, 小蓝视频色情网页版 data shows.

$30M to electrify trains with batteries and microgrids

Let鈥檚 now turn from waterways to train tracks, with another company that recently raised significant funding aimed at giving centuries-old transportation systems a green overhaul.

, a Philadelphia-based startup, said last month that it raised $30 million in seed funding led by Australian mining company and Israeli venture firm to develop a new way of powering freight rail that avoids the high costs of traditional electrification.

The startup positions its technology as a way to decarbonize one of the world鈥檚 most efficient but still fossil-fuel-dependent transport systems. It鈥檚 targeting a major pain point for the rail industry: its heavy reliance on diesel. In North America alone, the six largest freight rail operators spend roughly $11 billion annually on diesel fuel, while full electrification of rail networks could cost more than $1 trillion, according to Voltify.

Instead of relying on overhead wires, Voltify says it鈥檚 building a system that combines battery-equipped railcars with technology that allows trains to recharge while moving. The goal is to help rail operators cut emissions and fuel costs without requiring massive infrastructure overhauls.

Its approach 鈥� using mobile batteries and distributed charging via microgrids 鈥� aims to sidestep those costs by retrofitting existing trains and building localized energy systems rather than rebuilding entire rail networks.

CEO and co-founder that the company has signed a paid pilot agreement with a Class 1 railroad, though she declined to name the customer, citing a confidentiality agreement.

She noted in a that raising funding for a transportation company in the current market was difficult. 鈥淪ecuring capital in the hardware space and traditional industries is challenging,鈥� she wrote. 鈥淚t is not the 鈥榠n鈥� space; there is no FOMO at play, so we need to focus on metrics and execute quickly. With some of the top 5 largest rail companies globally and a large order pipeline, we are determined to keep moving at lightning speed.鈥�

$7M for foundation AI for biology

Funding to foundational model AI startups surged last quarter, reaching $178 billion, per 小蓝视频色情网页版 data. But the vast majority of that funding went to AI giants like and that are building general-purpose GenAI models.

Such models are fundamentally lacking for hard sciences, argues , a startup based in Paris and Berkeley, California, that last month raised $7 million in seed funding to develop foundation AI for biology trained on DNA, RNA and data from other 鈥溾�� fields, rather than human text.

The company鈥檚 first family of transformer models is called Botanic and is trained on data from 43 plant species. Living Models noted that it鈥檚 starting with the commercial crop industry, a massive global market that has abundant data, well-established research infrastructure, and fewer regulatory concerns and faster commercialization timelines than the pharmaceutical industry.

鈥淧lant biology combines three properties that make it an ideal first domain for biological foundation models: genomic data is abundant and largely unrestricted, the commercial need is acute and quantifiable, and the feedback loop between computational prediction and real-world validation is well established through existing breeding infrastructure,鈥� the company said in a statement.

The global seed industry is also dominated by a handful of incumbents, it noted: , , , and 鈥斕齝ompanies that already spend billions of dollars a year on breeding research.

鈥淏iology is an information problem at every scale, from a single cell to an entire ecosystem. The genomic data exists across many domains; what’s been missing is a model architecture capable of learning from it at scale,鈥� , Living Models鈥� CTO and co-founder, said in a statement. 鈥淲e start with plants because the data is rich and the breeding cycle is a clear bottleneck, but the same approach applies wherever sequence data meets slow, empirical discovery.鈥�

$2.1M for a brain-stimulating consumer wearable

Billions of dollars a year are spent on therapy and other mental-health treatments, yet measuring progress can be elusive.

That鈥檚 one of the issues that San Francisco-based aims to take on with a neuromodulation wearable headset that it says can reduce stress, improve attention span and mood, and more quantitatively measure mental health scores.

Mave鈥檚 device uses transcranial direct current stimulation, or tDCS, a noninvasive technique that delivers a low electrical current to the brain through electrodes placed on the scalp, with the aim of modulating neural activity. The technology is when used by adults as directed in controlled settings.

The company last month raised $2.1 million in seed funding led by , with participation from individual investors including Autopilot AI lead .

Crucially, Mave says it does not plan to pursue medical-device approval for its product, which sells for $495. Instead, it is positioning the gadget as a wellness tool that consumers can use on a daily basis to improve their mental well-being and better measure the outcomes of talk therapy or other treatments.

鈥淚f you ask a psychologist how do you know if a person is making progress, their response to it is very standard, which is that it鈥檚 not about progress. It鈥檚 about process [鈥 But for somebody with depression who is spending a lot of time in therapy, progress is important. So how do you know whether they鈥檙e making progress or not? And even these basic questions were not being answered,鈥� co-founder .

Mave鈥檚 funding comes amid an overall downturn in investment for wellness and fitness-related companies, although select wearables makers including and have raised significant funding in recent years.
