The Brainchild of an ER Doctor, Crossover Health Focuses on Data and Preventative Care

Once an obscure health care company, Crossover Health has netted some of the biggest names in technology. And its new venture with Amazon is about to make it even bigger.

The San Clemente-based startup netted $168 million in Series D funding just this week, and its burgeoning success speaks to a larger trend that could change how U.S. health insurance is done.


Once a small health care provider co-founded by two colleagues in Aliso Viejo, Crossover Health has grown into one of the biggest names in the industry and is expected to rake in $165 million in revenue by year's end.

Facebook, LinkedIn and Comcast are among its clients and its providers now oversee 400,000 patients across the country. But their most well-known partnership is with Amazon, which is using the company to power their 17 in-person clinics, including one near its fulfillment center in San Bernardino.

Crossover promises to lower the cost of health care for employers by providing primary and preventive health care at a pre-fixed rate. In addition, it says it can save companies 15% on average on their health care costs by emphasizing preventive care.

Co-founder Scott Shreeve said he started to think about this idea after seeing a rotating door of patients with various ailments in the emergency room.

"I would do my best to take care of my 30 or so patients every day that came in and try to address their issues," Shreeve said. "And then the next day there'd be 30 more, and then 30 more. It just felt like, 'what can I do to get ahead of this, to get upstream of these problems?'"

Crossover's Series D round was led by Deerfield Management Company. The goal is to help the company grow faster.

Founded in 2010 by Shreeve, an emergency medicine doctor, and health insurance expert Nate Murray, the company runs 48 health clinics that are based employer sites or close by. The company, like Forward and One Medical, uses comprehensive analytics platforms to track and enable patient health care.

Crossover nabbed its first big client, Apple, in 2011 as the tech giant was developing on-site clinics.

Its success can be attributed to the growing number of self-insured companies. Rather than paying money to an insurance company, a business will take on the risk of paying health care providers itself. They often still use insurance to handle the administrative tasks, but use primary health clinics like Crossover Health to handle the everyday needs of their employees.

Crossover Health announced a partnership with Amazon in 2020 to develop a slew of health clinics scattered across the country meant for Amazon workers who might work odd hours. It has opened up 17 clinics in five states, including the San Bernardino area. The clinics operate from 7 a.m. to 11 p.m. and offer everything from primary care to behavioral health services for workers and their families.

"If you come in and you've got a back injury that's that's causing depression, we're not going to just treat your back injury and punch you out of here," Shreeve said. "We have a physical therapist and a mental health therapist as part of a similar team and they work to provide that comprehensive care."

Crossover Health may not be Amazon's only provider. Wyoming-based Care Medical, which contracts with Amazon to offer Washington employees in-person and virtual care, filed paperwork to do business in other states, according to STAT News. It is unclear if this is a joint venture with Amazon.

A New Model for Tech Companies

Many tech companies have adopted on-site or near-site clinics in order to proactively lower health insurance costs. If employees have easy access to quality primary and preventative care that can manage or stave off chronic conditions, the employer pays less on reactive care for high-risk issues.

The self-insured model has historically worked best for large businesses who can offer hundreds of employees to, and afford to broker deals with, health care providers. Eighty-four percent of large companies were self-insured in 2020. Disney and Walmart are both self-insured, and Walmart flies its employees over state lines to see specialists in its network.

"If you're a little company and you have one person that works for you that has a really bad accident, that can blow your budget for five years. Then you have to buy reinsurance to protect you against that," Glenn Melnick, a professor at the USC Price School of Public Policy. "There's no savings there... whereas if you're a big company, administrative costs are spread out among a lot of employees."

In addition to Crossover Health's on-premise and virtual clinics staffed by doctors, therapists and other care providers, the company offers fitness classes and resources on grocery shopping and other extrinsic factors that play a role in determining one's health.

"They have a real incentive to keep all their members healthy," said Eunjoo Pacifici, a professor at the USC School of Pharmacy. "Their expenses are kind of fixed for paying for doctors and infrastructure. If they can keep the cost of care down, they can keep more of their profits."

It also has a network of specialists and can schedule appointments with them on behalf of a patient. Specialists are not covered under Crossover Health. The company uses an in-house data analytics technology platform that allows them to collect an employee's medical history with their permission, create a baseline of health, track 40 metrics of health, identify potential risk factors and proactively encourage employees to get treated.

The platform is a portal by which patients can securely contact health care experts and access their health records. In turn, Crossover Health recommends flu shots, physicals and other services based on the employee's health profile.

While this model is shown to be effective in managing care, according to Melnick, not all preventative health care is cost effective. Some chronic diseases — like diabetes, cancer and heart disease — require years of preventative health care to slow the effects, and those preventative treatments may not outweigh the cost of treating the disease.

"It improves quality of life," Melnick said. "There are other reasons to do it, but for other things it is not economically justified."

Crossover Health says while chronic conditions are more expensive to treat, they're balanced out by the employees who require very little care.

Why Samsonite Just Paid $178.5M for BÉIS

🔦 Spotlight

Hello, Hello.

This week, one of LA’s most recognizable consumer brands packed its biggest bag yet.

Samsonite Group has agreed to acquire an 85% stake in BÉIS for $178.5M, valuing the Los Angeles-based travel and lifestyle brand at approximately $210M. The deal is expected to close in Q4, pending regulatory approval.

Founded by actress and entrepreneur Shay Mitchell and incubated by LA-based Beach House Group in 2018, BÉIS has grown from a digitally native luggage startup into a profitable business that generated approximately $210M in sales last year. Along the way, it built the kind of fiercely loyal online following that legacy brands spend years and considerable marketing budgets trying to manufacture.

Image Source: BÉIS

That may be the most interesting part of this deal. Samsonite is not simply acquiring another luggage line. It is buying access to a younger, predominantly female customer base, a sophisticated direct-to-consumer operation and a brand that knows how to turn social media attention into actual sales. The suitcases are useful; the cultural relevance is the real carry-on.

BÉIS will continue operating as a standalone brand under CEO Adeela Hussain Johnson and its existing management team. Mitchell will retain a 15% ownership stake and continue guiding the company’s creative and product vision, while Samsonite brings the global distribution, sourcing and logistics infrastructure needed to take the brand further.

For LA’s startup community, the acquisition is another reminder that valuable technology companies do not always look like software companies. BÉIS built its advantage through digital distribution, community and an unusually sharp understanding of its customer. Now, one of the world’s largest luggage companies wants what it created.

Sometimes the strongest exit starts with knowing exactly what people want to pack.

      Two LA Startups Raised $2.37B to Build What AI Needs

      🔦 Spotlight

      Happy Friday, LA.

      The largest checks in tech are increasingly going toward companies trying to build their way out of America’s biggest physical constraints.

      This week, two Los Angeles startups raised a combined $2.37 billion in equity to tackle two particularly urgent ones: how the country manufactures critical hardware and where it will find enough electricity to power the AI era.

      Torrance-based Hadrian is building highly automated factories for defense and aerospace. El Segundo’s Valar Atomics wants to manufacture nuclear reactors at scale. Different industries, same underlying bet: the next generation of technology will depend on our ability to produce physical infrastructure much faster than we do today.

      Hadrian raised $1.37 billion in Series D funding, bringing its valuation to $7.87 billion. The company plans to use the capital to open new factories, expand research and development, and increase its capacity to produce critical defense, aerospace and industrial systems.

      Hadrian’s pitch is straightforward, if wildly ambitious: America needs to relearn how to build things and build them quickly.

      Its factories combine skilled workers with AI, robotics and proprietary software to manufacture precision components and, increasingly, complete mission-critical systems. Its customers include defense giants such as Lockheed Martin and RTX, along with newer players like Anduril.

      The company has come a long way from simply making aerospace parts. Hadrian is positioning itself as a piece of America’s industrial infrastructure, offering manufacturers a way to rapidly scale domestic production at a time when wars abroad, strained supply chains and growing defense demands have made the country’s manufacturing gaps increasingly difficult to ignore.

      Investors are clearly buying the argument. The new round comes just over a year after Hadrian raised $260 million, suggesting that “reindustrialization” has officially graduated from venture capital buzzword to billion-dollar investment thesis.

      Meanwhile, roughly 15 miles away in El Segundo, Valar Atomics is moving even faster than its enormous ambitions suggested.

      When we last wrote about Valar, the company was reportedly raising $450 million at a $2 billion valuation and racing to prove that nuclear energy could move on AI’s timetable. Now, it has closed a $1 billion Series B led by Sequoia Capital, secured an additional $200 million credit facility and reportedly reached a $6 billion valuation.

      Valar is developing standardized, factory-built nuclear power plants designed to avoid the enormous costs and decades-long construction timelines associated with traditional nuclear projects. Its goal is not merely to build a working reactor, but to eventually manufacture fleets of them.

      That ambition also sounds considerably less theoretical than it did when we first covered the company. In June, Valar’s Ward 250 reactor achieved a self-sustaining nuclear reaction. Just one week later, the company demonstrated the reactor generating electricity to power an Nvidia Blackwell system. Valar now says the new funding will help it move from proving its technology works to producing reactors at scale.

      The timing is no coincidence. AI’s enormous appetite for electricity is forcing the tech industry to confront a basic reality: the cloud still has to plug into something. Training models and operating massive data centers will require far more reliable power, and nuclear energy is rapidly becoming one of Silicon Valley’s favorite answers.

      Hadrian and Valar may be solving different problems, but their unusually large rounds point to the same shift. AI can design, predict and automate, but it cannot manufacture a missile component or generate a megawatt of electricity on its own. That requires factories, energy systems, supply chains and a great deal of capital.

      For years, venture-backed companies competed to build the software layer. Now, some of the biggest bets are being placed on the infrastructure underneath it.

      The future may run on AI. But first, someone has to build what keeps it running.

          How Replify Found Its Niche and an Acquirer

          🔦 Spotlight

          Hello LA,

          This week’s startup story began three years ago with an AI assistant built for almost any small business. It ended, or perhaps graduated, with an acquisition by one of the fitness industry’s largest technology providers.

          ABC Fitness has acquired Replify, an AI platform that manages customer communication for gyms and wellness businesses across phone, text, email and chat. Its virtual agents can answer questions, qualify leads, schedule tours and classes, follow up on missed calls and run outbound campaigns. Financial terms were not disclosed.

          Before Replify found its footing in fitness, it was HeyLibby, a general-purpose AI assistant founded in 2023 by former Zillow colleagues Spencer Rascoff, Tony Small and Anna Rodriguez. The company was incubated inside Rascoff’s 75 & Sunny Labs and initially set out to help small businesses turn incoming messages into qualified leads.

          That broad vision gave HeyLibby a large potential customer base, from real estate agents and contractors to hairstylists and event planners. But as the team searched for product-market fit, one industry’s problem stood out. Gym and wellness employees were often too busy helping customers in person to answer every call, text or email, leaving prospective members waiting and potential revenue on the table.

          That insight reshaped the company. HeyLibby narrowed its focus to fitness and wellness, raised a $4.5M seed round in 2025 and later rebranded as Replify. It went on to work with brands including Gold’s Gym and UFC Gym, proving that its AI agents could do more than answer routine questions. According to the company, customers have captured up to 10 times more leads and shortened sales cycles from roughly 30 days to as little as three to five days.

          ABC Fitness became a natural next step. The company provides software to more than 30,000 fitness businesses serving over 40 million members worldwide. By adding Replify to its platform, ABC can offer gyms an always-available AI front desk while bringing Replify’s technology to a much larger global customer base.

          Replify’s journey offers a useful lesson amid the rush to build AI products for everyone. The company began with a broad promise, identified a customer with a specific and expensive problem, and built deeply around that need. Gym owners did not need another flashy chatbot. They needed someone to answer the phone when the front desk could not.

          Sometimes the smartest AI strategy is simply picking up the call.
