A month after she died at the age of 87, Marina Helen Smith spoke at her own funeral.

Smith, the co-founder of the U.K.’s National Holocaust Centre and Museum, addressed her friends and family last week through a prerecorded video. Yet Smith was able to answer some questions during the memorial service, too. After her son, Stephen Smith, asked what she’d say at her funeral, she delivered a brief speech about her life and spirituality. She also answered questions about loved ones who attended the ceremony, creating the illusion of a real-time conversation.


Smith’s interactive video was made using tech from her son’s startup, Los Angeles-based StoryFile. Launched in 2017, the company lets people create videos that can reply to viewers’ questions, using artificial intelligence (AI) to play relevant video clips as responses. Initially conceived as a way to preserve stories of Holocaust survivors and talk to other historical figures, StoryFile’s videos are now showing up at funerals, CEO Stephen Smith said. After losing his mother, Smith understands why.

“I don't find it in the least bit weird to bring up my mother's StoryFile and talk to her,” he told dot.LA. “It's strange to say that but it feels, actually, very natural.”

StoryFile is part of an emerging tech trend practically pulled from the plot of a sci-fi novel. Tech companies have made tools that let people talk to the dead, from digital memorials to chatbots impersonating the deceased. In addition to helping people mourn and remember loved ones, such programs can serve as educational tools. But experts warn similar tech has been deployed for nefarious purposes, like spreading misinformation.

In June, Amazon showed how its Alexa virtual assistant could read a bedtime story in a dead relative’s voice, based on a short audio recording of the deceased person. It’s unclear whether that capability will become an Alexa feature, as it remains in an “exploratory research” stage, a company spokesperson told dot.LA.

Microsoft has also shown an interest in virtually reviving the dead, patenting a chatbot that pulls data from a person’s social media posts. More recently, the software giant said it would restrict customer use of AI that can impersonate someone’s voice, noting the tech “has exciting potential” but could be used to “deceive listeners.”

Tech bringing the dead back to life has shown up in Hollywood, too, and not just as a storyline for Netflix’s “Black Mirror.” In 2019, Disney included late actress Carrie Fisher in a “Star Wars” film by combining real footage of her face with a completely digital character.

StoryFile’s videos aren’t that creepy. At least not yet. The 40-person startup doesn’t put words in anyone’s mouth or try to create new facial expressions like so-called “deepfake” videos. The StoryFile clips use only pre-recorded answers for a limited—but still long—list of possible questions. If you pose a question the subject doesn't have a recorded answer to, they’ll encourage you to ask something else.

That said, StoryFile’s Smith showed dot.LA demos of its more advanced “digital recreations,” which would let people talk to historical figures like Elvis and Albert Einstein, who obviously were unavailable for interviews. Smith believes such videos could potentially be educational, letting students of the future learn physics from a digital Einstein.

The StoryFile idea can be traced to 2010 when Smith’s wife, Heather Maio-Smith, was creating a historical exhibit about Holocaust survivors. She wanted to create “engaging conversations” that would let people interview survivors rather than simply hearing a “linear” oral history, Stephen Smith said. They developed the interactive interviews through a partnership with the University of Southern California. Eventually, the Smiths launched StoryFile to capture stories from historical figures and everyday people. Heather serves as StoryFile’s chief visionary officer.

“How do you communicate best with the past? It's when you ask questions about the past,” Stephen Smith said. “It becomes a relationship with the past, not just that history that's told to you.”

StoryFile’s Conversa AI has been used to create interactive interviews with the still-living likes of actor William Shatner and, more recently, Clarence Jones, the personal counsel of Martin Luther King Jr. The company also has commercial clients using interactive video for customer service or employee training. StoryFiles popping up at funerals, however, was a total surprise, Smith said. Late actor Ed Asner’s memorial notably included such a video.

Other startups see a market opportunity in interactive digital memorials. El Cerrito-based HereAfter AI pairs user photos and audio interviews to similarly let family members talk to recordings of loved ones on their computers, smartphones or smart speakers. Cofounder and CEO James Vlahos got the idea after creating “Dadbot,” a chatbot that shared his father’s life story and personality when he was diagnosed with terminal lung cancer.

Some HereAfter AI customers have recorded interviews for up to 10 hours, Vlahos told dot.LA. “Once you get people rolling, talking about their lives, they have a lot to say,” he noted. The market for this kind of product is still relatively small, with only a handful of direct competitors, he said.

Like StoryFile, HereAfter AI doesn’t use its tech to generate answers to questions that weren’t asked during an interview. Vlahos called that a “sensitive area.” On one hand, letting AI form its own responses would make the chat experience more flexible and powerful. On the other, synthesizing what grandpa might have said starts “crossing that line,” Vlahos said.

“We might get it wrong, and that might be really hurtful to someone,” he said. “Or if nothing else, it might be kind of creepy.”

More advanced “deepfakes,” which use AI to create convincing video and audio hoaxes of someone’s likeness, have gained widespread attention and criticism. Recently, a fake clip of Ukrainian President Volodymyr Zelenskyy made it look like he surrendered to Russia. Fraudsters could deploy similar programs to steal someone’s identity, too, experts said. Unlike the living, dead people can’t correct the record if a video is bogus, creating a unique set of ethical and philosophical questions.

Legitimate commercial ventures deploying the tech make sure users know they’re not talking to a real or living person, said Arizona State University professor Subbarao Kambhampati, who teaches computer science. “But the real issue is, what if you don't know? And that can be very easily done,” he added. As such tech becomes more ubiquitous, Kambhampati predicts more people won’t trust their eyes and ears.

“I think in the longer term, we will get used to it. We will no longer just directly trust what we are hearing and seeing,” he said. “But it's the transition that's going to be tricky, because many people can be taken because we still tend to believe what we hear, what we see, so that skepticism has to increase.”

The tech could also be applied in the metaverse, a nascent vision for the internet where we might work, shop and socialize inside 3D virtual environments. Students may one day strap on virtual reality headsets and watch Abraham Lincoln deliver the Gettysburg Address—then ask the president some follow up questions.

“I think there's a lot of good that will come out of this,” said Majid Abai, founder and CEO of Seena AI, a software and app development firm in Los Angeles. “Now, not only can I see a video, but I can also put a headset on and meet up with a loved one in the metaverse.”

In January, Stephen Smith asked his mother scores of questions over two days to record her StoryFile. She spoke candidly about her upbringing in India and childhood difficulties transitioning to England. Smith said he learned new things about her past, such as when she had measles as a child and was put in quarantine for four months, seperated from her parents.

“I didn’t know that story. She never mentioned it,” Smith said. “Things that she'd [previously] not revealed were revealed. I was grateful for that information about her.”

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.

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.

      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.
