In October 2024, my co-founders and I set out to make our Ph.D. research useful in the real world. We had built AI models that could interpret medical images such as X-rays and CT scans across tens of thousands of potential diagnoses, generating comprehensive radiology reports that mirror how radiologists reason in clinical practice. At a time when AI in radiology was limited to flagging a handful of specific conditions, this marked a fundamental shift.

Less than a year later, we faced a critical fork in the road: raise venture capital and continue independently, or accept an acquisition offer from , the world鈥檚 largest radiology practice.

The conventional wisdom in tech is that real ambition means staying independent. But in asking ourselves what it would truly take to transform healthcare, the answer was different.

Clinical AI is highly regulated with long sales cycles and complex stakeholder dynamics, where structural advantages tend to harden market positions and compound over time. We decided that joining forces 鈥� carefully structured to protect our velocity 鈥� would dramatically improve the odds that we realize our mission of significantly increasing the world鈥檚 access to healthcare.

Research success is not clinical readiness

During my Ph.D., I trained radiology AI foundation models on what, at the time, felt like massive research-scale datasets; tens to hundreds of thousands of studies. These models make for strong academic demonstrations, prototyping new capabilities across a range of tasks. In real clinical settings, however, they would not yet have met the standards required for production-level safety and consistency in patient care.

Despite the persistent narrative that AI will make radiology obsolete, the reality is that the problem is extraordinarily difficult. A single CT study, for example, can contain 10 high-resolution volumetric series, effectively 3D videos. Add prior studies for the same patient, and you can have a billion pixels of data.

Those billion pixels encode entire medical textbooks worth of information. On top of this, real-world radiology is defined by edge cases where rare but critical pathologies are encountered regularly. We learned a hard truth early on: Models that work in controlled research environments often fall apart when exposed to real-world complexity.

Think about self-driving cars. A decade ago, progress looked impressive. But the real world kept introducing new failure modes. After more than a decade of significant capital investment, only a handful of companies have approached true reliability.

Components required to build reliable models

Key patterns emerged. The companies that made the most progress controlled the entire system and achieved scale early. They owned the vehicles, the sensor stack, the data collection pipeline, the simulation environments, and the deployment infrastructure. That integration, operating at scale, allowed them to continuously collect rare edge cases, retrain models, validate improvements and redeploy safely.

Radiology is no different. Success in the real world requires massive, diverse historical datasets and live data feeds that continuously surface rare edge cases and distributional shifts. It requires vast clinical resources and operational infrastructure to redesign clinical workflows around AI, engineer systems that perform reliably at scale, conduct large-scale research studies, secure regulatory clearance, refine models safely, and continuously monitor performance post-deployment.

Additionally, frontier language models have clearly demonstrated that continuous, high-quality and extensive human feedback is the secret sauce in making models useful. This is no different in radiology. In a world where radiology reports are drafted by AI, every draft must be reviewed, edited and signed off by a human radiologist.

Those edits become high-quality signals that can be leveraged for improving the AI models. Better models elevate radiologists’ accuracy and capacity. Improved radiologist accuracy increases the quality of future training data. Increased capacity allows radiologists to take on additional contracts.

That, in turn, generates more data and high-quality corrections, setting a powerful flywheel in motion. Access to this correction data is rare in AI and can only work meaningfully at a massive scale. These capabilities would be incredibly difficult to achieve as a standalone AI startup.

In healthcare, growth follows evidence

In healthcare, trust is hard earned. It rests on demonstrated clinical efficacy, reliability, security and regulatory rigor. For a health system or radiology group to adopt technology from a new startup, particularly in workflows that directly affect patient care, requires rigorous, real-world evidence.

Evidence in healthcare is not generated in small pilots. It is built through sustained performance across diverse sites, patient populations, modalities and edge cases. If a system proves itself within the world鈥檚 largest radiology practice, it establishes credibility across multiple dimensions at once 鈥� efficacy, reliability, security and scalability.

In sectors where lives are at stake and the goal is to build something that endures, the way to build it is from within the system you鈥檙e trying to improve. Selling early didn鈥檛 shorten our journey, it accelerated it. It gave us the foundation required to deliver on our mission of significantly increasing the world鈥檚 access to healthcare.

During his undergraduate studies in physics and electrical engineering, he became driven by a singular mission: increasing the world’s access to healthcare through technology. Convinced that AI was the most promising technology to make this happen, but not yet good enough for real-world clinical use, he pursued a Ph.D. in AI at where he focused on foundation models for radiology. His doctoral work produced Merlin, a 3D vision-language model for CT interpretation published in 鈥淣ature鈥� in 2026 and recognized as one of the most important papers in the field.

Still, Europe saw more capital going into fewer companies in Q1, with deal volume plummeting 40% year over year. Much of the decline was at seed stage (down 44%) and early stage (down 30%), while late-stage deal volume was in-line with the previous four quarters.

AI above 50%

Funding to Europe-based AI startups increased significantly last quarter, reaching $9.2 billion, or more than half of total venture funding to the region. That marks the sector鈥檚 highest proportion in a quarter on record.

The largest four rounds to startups based in Europe in Q1 were for AI-related companies. Data center builder , autonomous driving developer , and frontier lab for physical AI raised more than a billion each, and AI legaltech 鈥檚 funding totaled more than $500 million.

UK and France grew YoY

Startups from the U.K. and France raised more funding in Q1, totaling $7.4 billion and聽 $2.9 billion, respectively. Germany-based startups raised $1.9 billion, flat year over year.

France has emerged as the European leader for AI frontier labs. Last quarter, it saw Paris-based , founded by former AI chief , raise $1 billion in the continent鈥檚 largest seed funding round on record. The deal also marked only the second billion-dollar-plus funding deal for a European frontier lab, following s $2 billion round last year.

Europe by stage

In Q1, late-stage funding to Europe-based startups nearly doubled from a year ago. The largest rounds were across a variety of sectors, including AI hardware, fintech, agentic AI, productivity software, sensors, defense, e-commerce and energy.

A total of $9.2 billion was invested at late-stage across 83 deals, up 91% by amounts year over year.

Early-stage funding to the region鈥檚 startups fell from a year earlier 鈥� by around 20% 鈥� 附近上门 data shows. Early-stage investment totaled $5.3 billion in Q1 across more than 240 funding rounds. Within early-stage funding, larger Series A rounds predominated in semiconductors, energy and healthcare.

Seed funding reached $3.1 billion in Q1 across more than 790 deals. The funding total was up 50% year over year, but largely due to the $1 billion round for Advanced Machine Intelligence.

In summary

Larger rounds into critical sectors in AI drove European startup funding up in Q1. A mix of Europe- and U.S.-based investors led the largest fundings last quarter into AI infrastructure, frontier labs, autonomous systems and applications.

Overall, Europe is in-line with global trends as capital concentrates into the largest deals in sectors that are surging due to AI.

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.

$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, 附近上门 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 鈥斅爐he Middle East and Southeast Asia.

$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.

$7M for foundation AI for biology

Funding to foundational model AI startups surged last quarter, reaching $178 billion, per 附近上门 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.

Individual investors in the round include soccer star , players and , and musician .

Whoop says it is powered by more than 24 billion hours of physiological data and purpose-built AI models to provide predictive, personalized health insights. It claims to help users understand how they slept, whether they have recovered, how hard to push or pull back, and how daily behaviors like training, nutrition and stress are impacting their performance and long-term health. It further ambitiously claims that it helps users 鈥渋dentify early warning signs, reduce risk, and take action that can prevent serious health events.鈥�

Subscription-based insights

Its model is different from that of many wearables companies. The actual wearable doesn鈥檛 cost anything, but 鈥渕embers鈥� pay a subscription to access the insights it offers. There are different tiers based on style and performance level.

Whoop has historically been more popular among athletes and die-hard workout enthusiasts, although it appears to be becoming more mainstream. The company says it now has over 2.5 million members globally, and that in 2025 bookings grew 103% year over year. It聽 operated cash flow positive and ended the year at a $1.1 billion run rate.

The company is actively hiring for over 600 roles as it plans to double down on R&D and global expansion across Europe, the Middle East, Latin America and Asia.

Whoop鈥檚 round is a bright spot in a sector that hit a cyclical low last year after peaking about four years ago. Just over $5 billion in global venture funding went to fitness and wellness-related startups in 2025, 附近上门 data shows.

Venture firms that set up shop in the Texas capital city included , , and 1, among others. famously moved 鈥檚 headquarters to Austin in 2021, while also purchasing a house and establishing a residence there.

But as more employees returned to in-office work, Austin slowly seemed to fall out of favor with the tech community, some of whom said it had been overhyped as a startup hub.

There were reports of tech workers who had moved to the city during the pandemic and , saying they were going back to places like the Bay Area. Musk back to California in 2023.

Funding tops pandemic peak

Undeterred by the 鈥渢ourists,鈥� the startup and venture community in Austin kept plugging away. And those efforts are reflected in a surge in funding to startups headquartered there last year, with 2025 posting an all-time high for Austin venture investment, 附近上门 data shows.

Investment into Austin-based startups spiked 64.8% to $7.19 billion in 2025 as more investors poured money into companies based in the region, according to 附近上门 . That鈥檚 compared with the $4.37 billion raised by Austin-area startups in 2024 and tops even the $6.1 billion raised in 2021, at the height of the venture funding frenzy.

Notably, deal counts actually decreased from 312 in 2024 to 272 year over year, signaling an increase in later-stage deals. Indeed, the data corroborates that with $4 billion of the total raised in 2025 classified as late-stage rounds.

Last year鈥檚 totals were also more than double 鈥� 130% higher 鈥� than the $3.1 billion raised in 2023. That money was raised across 403 deals, signaling much smaller round sizes at the time and a more mature market.

A tech scene decades in the making

, managing partner of , doesn鈥檛 believe that the Austin funding performance in 2025 was anomalous.

Rather, he calls it 鈥渢he payoff from decades of compounding.鈥�

鈥淭alent density in venture categories such as software, fintech, health tech, defense and聽 robotics has reached a critical mass, driven by waves of Bay Area relocations, both full HQ moves and satellite offices, that brought technical, product and operational talent into the market,鈥� Flager said.

That talent eventually left to build new companies, he said, and the cycle repeated.

鈥淥n the capital side, the stack has matured across all stages, from pre-seed through growth, with local firms that have now cycled through multiple funds and understand the market deeply,鈥� Flager said. 鈥淟ayer in a business-friendly regulatory environment, a relatively lower cost of living, as well as a lower effective tax rate, and Austin becomes an attractive place to start and scale a company.鈥�

Former Austin Mayor saw so much potential in the city鈥檚 startup scene that he began a career in venture investing after his tenure ended in early 2023. (He now works for New York-based ).

Part of the city’s success as a startup hub stems from its reputation as a haven for mavericks and risk-takers, Adler has said.

鈥淢ost cities in the world, you try something, you fail; it’s hard to have access to the capital the second time,” he told co-founder in a in 2022. “In Austin, the civic folk heroes are the people that tried something and it didn’t quite work out and they worked on it until it did.鈥�

, founder of , a solo GP venture firm based in nearby San Antonio, said that it feels like Texas and the Austin metro area specifically are becoming more attractive to manufacturing- and engineering-heavy businesses.

鈥淪ome of that may be thanks to Tesla, and some of it may simply reflect the physical advantages of the state,鈥� he told 附近上门 News. 鈥淓ither way, this [surge in financing] feels less like hype returning and more like capital concentrating around a narrower set of serious, technically differentiated companies.鈥�

Deal sizes grow

That diversity among funded startups is reflected in last year鈥檚 investment totals for Austin, which were boosted by several large, late-stage deals across a broad range of industries.

The largest was a $1 billion Series C round for energy provider in October. New York-based led that financing, which valued the 2-year-old company at $4 billion.

Looking back, February in particular was a busy month for venture funding. That month alone saw the second-, third- and fourth-largest rounds in Austin for the year. They included:

• A February Series C round in which autonomous surface vessels maker raised $600 million at a $4 billion valuation. led the round for the defense tech startup.
• Also in February, , which provides endpoint management, security and monitoring, raised $500 million in Series C extensions at a $5 billion valuation 鈥� more than doubling its value from just 12 months prior. The funding came in separate tranches led by and 鈥檚 , with participation from other investors.
• Robotics company in February raised $415 million in Series A financing led by聽 and accelerator (A $520 million extension to that Series A was raised in February 2026, taking the total round to over $935 million.)

The findings correspond with Flager鈥檚 observations.

鈥淎 good chunk of the capital raised in Austin was driven by several large deals. Similar to what we saw across the U.S. in 2025, venture funding in Austin was more concentrated than it has been in the past,鈥� he told 附近上门 News. 鈥淩oughly 38% of the capital deployed went to the top five venture financings in Austin. I believe the top 10 deals nationally accounted for more than 40% of the capital raised last year. We’ll see if this trend continues into 2026 and beyond. The start of the year suggests it will.鈥�

, founding partner of , agrees, noting that from a dollars perspective, the surge in financings was driven by a handful of outsized capital-intensive deals in newer categories such as defense and deep tech.

鈥淭hese companies require a combination of technology, land for manufacturing facilities, and talent for manufacturing tasks. Austin has unique skillsets for that,鈥� he said. 鈥淚t has a density of three things: talent in deep tech with , and many others moving to Texas in light of favorable business conditions with expertise in these industries; expansive land around Central Texas that is inexpensive, especially compared to California; and lower cost manufacturing-related labor especially given the surge in manufacturing jobs such as at Tesla in recent times.鈥�

Burgeoning industries

Once upon a time, Austin was better known as home to software and CPG companies. And while those types of companies certainly still exist, a number of other industries are growing increasingly robust, as the local investors have pointed out.

As with many top tech markets, Flager said Austin has long been strong for application and infrastructure software, which is currently being challenged by AI. In his view, that talent has migrated to building 鈥渜uality鈥� vertical agentic software and AI-native businesses.

鈥淲e are seeing these companies grow quickly and build scale, while using less capital 鈥� which is exciting,鈥� he added. 鈥淭he domain experts who built and scaled application software companies here over the last two decades are spinning out to build the next generation of native AI businesses.鈥�

The market overall is also broadening in interesting ways. Defense and autonomy have emerged as breakout categories, with Austin becoming one of the stronger markets in the country for dual-use and autonomous systems companies, noted Flager.

鈥淭he combination of software and hardware skills now in Texas, along with a business-friendly regulatory environment, has allowed Austin to take a leadership position in these important and developing markets,鈥� he said. 鈥淓nergy tech is also a natural fit given Texas’ grid scale and the surging power demands of AI infrastructure.鈥�

Finally, robotics and advanced manufacturing are also gaining momentum, driven by deep engineering talent and the ability to scale manufacturing near Austin cost-effectively, allowing engineers, executives and other factory employees to coexist and collaborate in close proximity.

Srinivasan noted that his firm is seeing strong activity in vertical AI companies, or companies that serve vertical markets with AI that is tuned on specialized proprietary vertical data, often targeting the services and labor expenditures by their customers.

鈥淭hese companies deliver 鈥楽ervices as Software鈥� with close to software gross margins and pricing models that are based more on usage and outcomes as opposed to the traditional seat-based models,鈥� he said.

Srinivasan also expects the city to continue to see large funding deals in defense and deep tech, given the combination of local strengths and robust global demand for such products.

Continued momentum

Investors and companies continue to be drawn to Austin. In late December, San Francisco-based venture firm in the city. One of the firm鈥檚 founders, , also announced that he had personally moved to Austin. The firm鈥檚 other founder, , had lived and worked in the city since 2022.

In late March of this year, Musk to build two semiconductor factories totaling 100 million square feet in Austin to supply advanced chips for and Tesla. The venture, known as Terafab, aims to manufacture 1 trillion watts of computing power per year, he said. Media outlets valued the initiative at nearly

Also this week, Barcelona-based AI health tech startup announced it will open an office and hire in Austin.

CEO told 附近上门 News that with the company鈥檚 New York office already established, the next step was not just expansion, 鈥渂ut choosing the right place to build.鈥�

鈥淎nd we chose Austin for one reason above all: talent,鈥� he said. 鈥淎s an AI health tech company, our success depends on attracting exceptional people across engineering, data and life sciences. Austin has rapidly become one of the most competitive talent markets. The city is one of the fastest-growing in the United States. This brings together deep tech expertise, entrepreneurial energy and a growing concentration of healthcare innovation. Ideal for our goal of building an R&D hub. 鈥�

Coelho also points out that Biorce has witnessed a 鈥渢rend鈥� of people moving from the Bay Area to Austin, noting that 鈥渢he quality of life has gained notoriety.鈥�

鈥淏ut for us, this isn鈥檛 about following a trend,鈥� he added. 鈥淚t鈥檚 about building where the best people are 鈥� and where they want to be.鈥�
