How Real-Time Data Is Helping Physicians Track Their Patients, One Heartbeat at a Time

Are you a human node on a health-based digital network?

According to research from Insider Intelligence, the U.S. smart wearable user market is poised to grow 25.5% in 2023. Which is to say, there are an increasing number of Angelenos walking around this city whose vital signs can be tracked day and night via their doctor's digital device. If you've signed up to a health-based portal via a workplace insurance scheme, or through a primary care provider's portal which utilizes Google Fit, you’re one of them.

Do you know your baseline health status and resting heartbeat? Can you track your pulse, and take your own blood pressure? Have you received genetic counseling based on the sequencing of your genome? Do you avoid dairy because it bloats, or because you know you possess the variant that indicates lactose intolerance?


Data Interventions That Save Lives

For many people in Los Angeles, body computing devices mean the difference between life and death. According to Leslie Saxon, M.D., Executive Director of the USC Center for Body Computing, a number of her patients have heartbeat monitors which she can track in real-time via her laptop.

“We use this on-going data stream in a number of ways,” explained Dr. Saxon. “For example, in my clinic today, I had a patient who had diagnosed their own arrhythmia via their Apple Watch. They experienced a symptom, their watch alerted them, they came in immediately, and we knew what it was from the data.”

Leslie Saxon

This is important, Dr. Saxon continued, “Because we spend a lot of time and money on episodic arrhythmia. If a patient is already engaged in their own care and diagnosis, and we have the evidence to hand, it leads to not only a deeper understanding, but better health outcomes.”

One of her other patients, a young man with congenital heart disease, had a shock over the holidays. “He alerted me and I was able to sign into a website and access the crucial diagnostic data from his medically-regulated device and address his situation in an instant.”

Both on-going self-monitoring, and tracking reported data over time, is also changing the nature of medicine itself. “Everyone is talking about precision medicine today,” Dr. Saxon pointed out, citing the move towards targeting the right treatments, to the right patients, at the right time. “But it’s more than that. With these devices, we’re able to liberate ourselves from brick and mortar care centers, and use integrated health systems, like our Virtual Care Clinic, to push diseases out even further.”

The Potential of Self-Monitoring

For example, the Swiss-American photographer Jonathan Ducrest uses data as an everyday wellness tool. He’s signed up to self-monitor via devices, sharing data with his doctors, but is focused on using it to improve daily living. While based back in Zurich, for now, he’s still able to continue US-style health tracking via Forward, the subscription-based medical platform in Century City, which is useful when he returns to L.A. on assignment.

“I was intrigued by the whole data-driven process when living in L.A.,” he told dot.LA. “After getting the initial body scan, and tests, which delivered a baseline health analysis, I continue to use a combination of wearables like my Apple Watch and other devices to keep an eye on my vitals, including a connected scale and thermometer from Withings. I chose to set permissions and share all this data with my clinical providers, so we can review at my next physical. But I have it whenever I want to check it myself.”

The Purpose Behind Tracking

But, eight years on from the launch of the Apple Watch, has data fatigue set in for many? Have we reached peak monitoring?

“Wearables, monitoring and data alone are not going to save your life or replace a physician or surgeon,” Aoun told dot.LA. “Right now, devices enable people to capture data and information about the state of their health, but what is happening with all of this data? Where is it going? Is it being used in your doctor's office? Without a platform to ingest your data and translate it into actionable insights, wearables are mere data collection devices that have no real impact on your health.”

At his membership-based healthcare startup, Aoun decided to build out a full-stack solution combining software, hardware, data infrastructure, and doctors all under one roof - working towards rebuilding healthcare from the ground up.

“We help people understand what their data means and provide actionable insights to proactively manage their long-term health,” Aoun said. “The result is continual everyday care, in real-time, that extends beyond the exam room and can scale to millions of people.”

Offsetting Decline with Data

One thing is certain, life ends. But could data transform how we spend our lives - and how well it ends?

That’s what Pinchas Cohen, M.D. Dean of the USC Leonard Davis School of Gerontology is looking into now. School initiatives examine the increasing role technology can and will play in aging research and services. Dr. Cohen told dot.LA that his field has been greatly impacted by the interplay of wearables, data, physicians and patients.

“Technological innovation impacts every area of gerontology research,” confirmed Dr. Cohen. “We are on the cusp of exciting new fronts in developing genomic-based personalized interventions that can extend health spans, the number of years we spend in good health. The ability to capitalize on large datasets allows us to begin to predict who might be at risk for certain conditions and target treatment and prevention efforts accordingly.”

Gerontology researchers use a wide range of wearables and sensors to collect data on sleep, movement and heart health and other measures.

“These tools can help physicians monitor disease, detect changes and develop interventions,” said Dr. Cohen. “For example, studies are looking at whether these tools could help physicians detect cognitive changes earlier versus relying on physical exams alone. Aging involves a set of multifaceted processes and remote monitoring and other data-driven interventions have the potential to extend the amount of time we spend in good health.”

The Future of Data Driven Healthcare

At least two generations have now grown up with tracking personal data from digital devices, whether as part of the quantified health movement, with a nod to if not immortality then increased longevity. According to the most recent census, "Americans are projected to have longer life expectancies in coming decades. By 2060, life expectancy for the total population is projected to increase by about six years, from 79.7 in 2017 to 85.6 in 2060."

As we enter a new era of medicine, data has led us not just to precision and personalized health, as in how that new medication works on your symptoms today, not based on large-scale historic Big Pharma trials, but also to a vast increase in personal responsibility.

You’ve got the data coming out of your wearables, what are you going to do with it?

Who Gave the AI Access?

🔦 Spotlight

Happy Friday, Los Angeles.

The newest employee in the office does not need a desk, a salary or a coffee order. But it may have access to your company’s emails, financial records, customer data and software systems.

That raises a fairly important question: Who decides what an AI agent is allowed to do?

El Segundo-based cybersecurity company Saviynt is building its next chapter around the answer.

Carrick Capital Partners announced this week that it closed a $600M continuation vehicle for Saviynt, including a new $255M investment in the company. The transaction allowed Carrick’s existing investors to either take liquidity or remain invested, while also providing liquidity to Saviynt employees through a tender offer.

Continuation vehicles are not exactly known for making gripping Friday reading. The company behind this one is considerably more interesting.

Saviynt develops identity security software that helps businesses determine who can access their applications, data and infrastructure. Increasingly, however, “who” does not refer exclusively to a person.

Companies are deploying AI agents that can retrieve information, write code, communicate with customers and complete multistep tasks with limited supervision. These digital workers need access to company systems to be useful, but every new permission also creates another opportunity for sensitive information to be exposed or an unintended action to be taken.

In other words, AI agents may be tireless employees. They are not necessarily trustworthy ones.

Saviynt is addressing that problem through Zuma, its platform for discovering, securing and governing AI agents, large language models and other nonhuman identities alongside a company’s human workforce. The goal is to give businesses one place to determine what every identity can access, whether it belongs to an employee, a contractor, a software application or an autonomous agent operating at machine speed.

The opportunity appears to be growing quickly. Saviynt has surpassed $300M in annual recurring revenue, up from approximately $10M when Carrick first invested. The company says bookings have increased by more than 80% this year while customer retention remains at 96%.

The new investment was completed as part of the final close of Saviynt’s previously announced $700M Series B, which valued the company at approximately $3B. Carrick’s continuation vehicle was led by Coller Capital and co-led by HSBC Asset Management, giving the investment firm more time and capital to remain behind one of its strongest-performing companies.

For Saviynt, the funding will support further development of its identity platform, deeper integrations with major cloud and software providers and its push to become a central security layer for the agentic workplace.

That ambition reflects a broader change taking place inside companies. The first wave of enterprise AI focused largely on what the technology could generate. The next phase is about what it can actually do, and whether businesses can maintain control once AI moves from answering questions to taking action.

Saviynt is betting that identity will become the gatekeeper.

AI agents are gaining access to the digital workplace, whether corporate security teams are ready for them or not.

Someone still has to hold the keys.

      An LA AI Company Just Won Entertainment’s Backing

      🔦 Spotlight

      Hello LA.

      The entertainment industry has spent the past several years debating what generative AI could take from creators.

      This week, some of its biggest companies put money behind an AI startup promising to build something for them instead.

      Los Angeles-based Stability AI raised $76M in Series B funding from an investor group that includes Electronic Arts, Sony Music Group, Universal Music Group and Warner Music Group. AMD Ventures and Pacific Alliance Ventures also joined the round, while LA-based MANTIS Capital and Sound Ventures are among the company’s existing backers.

      The financing brings Stability AI’s total funding under CEO Prem Akkaraju to $232M, including two equity rounds and convertible notes. The company plans to use the new capital to expand its creative production tools, applied research and professional services across music, gaming and entertainment.

      The amount is notable. The names attached to it are the bigger story.

      Generative AI’s arrival in entertainment has been anything but quiet. Artists have questioned whether their work was used to train models without permission. Studios have faced pressure over how the technology could affect jobs. Record labels have pursued AI companies in court while simultaneously exploring how the same technology might fit into their businesses.

      Now, several of the world’s largest entertainment companies are investing directly in one.

      That does not mean the industry has resolved its concerns about AI. It means some of its biggest players would rather help shape the technology than wait to see what it becomes.

      Stability AI is positioning itself for that opening. Rather than focusing solely on general-purpose models, the company is building tools specifically for professional creatives. Its recently launched Stable Audio 3.0 was trained on fully licensed music and lets artists generate, edit and arrange audio through a web platform or directly inside digital audio workstations.

      Image Source: Stability AI

      That licensed-data approach is central to the pitch. The next phase of creative AI will not be decided only by which company produces the most impressive model. It will also depend on which companies can earn the trust of the artists, studios and rights holders whose work gives those models value.

      For its new strategic investors, the round offers more than financial upside. It creates a closer view into how generative AI may change production, a voice in how the tools develop and an opportunity to establish rules before those rules are established for them.

      For Stability AI, the backing provides something equally important: credibility inside industries that have every reason to scrutinize what it is building.

      The company now has capital and access to some of the largest catalogs, franchises and creative workforces in entertainment. What it does with that access will determine whether this becomes a meaningful alliance or simply an impressive collection of logos.

      Either way, the industry is no longer watching from a safe distance.

      It has entered the room.

      LA’s Air-Taxi Plans Are Coming Downtown

      While Stability AI is trying to change how entertainment gets made, Archer Aviation wants to change how people get to it.

      AEG and Archer announced plans to develop downtown Los Angeles’ first vertiport at L.A. LIVE, creating a potential new stop in Archer’s proposed electric air-taxi network ahead of the 2028 Olympic and Paralympic Games.

      Image Source: Archer

      The planned site would sit beside Crypto.com Arena and allow passengers to travel to and from the entertainment district aboard Archer’s Midnight aircraft. The company says its network could turn drives that take an hour or longer into electric flights lasting approximately 10 to 20 minutes.

      Archer has already identified SoFi Stadium, USC and Hollywood Burbank Airport as possible locations, with its recently acquired Hawthorne Airport expected to serve as the network’s central operating hub. As the official air-taxi provider of LA28 and Team USA, Archer has an unusually visible deadline for turning those plans into something tangible.

      AEG and Archer have completed an initial feasibility study of the L.A. LIVE site, including reviews of land use, airspace, power availability and community impact. The next phase will examine operations and the passenger experience.

      There is still a substantial distance between a proposed vertiport and a functioning air-taxi network. The infrastructure must be built, regulatory approvals must be secured and passengers must be persuaded that flying across the city is safer and more practical than staying on the ground.

      Still, few locations could make that future feel more real than L.A. LIVE. Millions of people already pass through the district for concerts, games and major events. Placing a vertiport there would bring urban air mobility out of the concept stage and directly into public view.

      Together, this week’s announcements show Los Angeles becoming a testing ground for two technologies still moving from promise toward everyday use.

      One could reshape how entertainment is created. The other could reshape how Angelenos reach it.

      In a city famous for both its creative industries and its traffic, that feels appropriately on brand.

          This Torrance Startup Just Raised $1B to Mass-Produce Hypersonic Missiles

          🔦 Spotlight

          Happy Friday, Los Angeles.

          Castelion has spent the past four years trying to prove that hypersonic missiles do not need to take decades to develop or cost so much that the military can only afford a limited supply.

          Now comes the harder part: producing them at scale.

          The Torrance-based defense startup raised a $1B Series C at a $13B valuation. The financing includes $800M in equity and a $250M revolving credit facility, making it one of the largest recent raises for an LA defense technology company.

          JPMorganChase’s Strategic Investment Group, Andreessen Horowitz and Carlyle co-led the round. Lightspeed Venture Partners, Lavrock Ventures, Altimeter, General Catalyst, T. Rowe Price and LA-based Interlagos Capital also participated.

          Castelion will use the capital to ramp production of Blackbeard, its low-cost hypersonic strike missile, while developing a longer-range precision weapon and new defensive systems. Hundreds of millions of dollars will go toward expanding manufacturing at Project Ranger, the company’s 1,000-acre production campus in New Mexico.

          Image Source: Castelion

          Blackbeard was designed in California, will be built in New Mexico and is expected to enter service in 2027. Castelion says it has already secured more than $500M in U.S. military contracts over the past 18 months and moved the missile from a clean-sheet concept to an official program in fewer than four years.

          That timeline is central to Castelion’s pitch. Traditional defense programs are often associated with long development cycles, limited production runs and eye-watering costs. Castelion is applying the rapid testing and vertically integrated manufacturing approach popularized by commercial space companies to weapons production.

          But a $13B valuation changes the standard. Castelion is no longer being judged as a promising startup with an impressive prototype. It is being funded like a company expected to become a major part of the American defense industrial base.

          The question is no longer whether a startup can build a hypersonic missile. It is whether one can manufacture thousands of them without losing the speed, discipline and cost advantages that made it disruptive in the first place.

          For LA’s defense ecosystem, that shift matters. The region has become home to a growing number of companies promising to modernize how America builds critical hardware. Castelion now has the capital, contracts and facilities to show what happens when that promise reaches the factory floor.

          The next test will not be in a pitch deck. It will be in production.
