Hello, Los Angeles!

With Super Bowl LIX coming up this Sunday, the buzz isn’t just about the Chiefs vs. Eagles matchup—it’s also about how tech is shaping the experience. From Snapchat’s interactive game-day features to Apple’s latest product launch, there’s plenty happening beyond the field.

Snapchat’s Super Bowl Features

If you're watching the game, chances are you’ll be on your phone just as much as your TV. This year, Snapchat is rolling out AR Lenses, live score updates, and Spotlight challenges to make game day more interactive. Want to try on your team’s jersey? There’s a Lens for that. Need real-time updates? Snap has them covered. Attending the game in New Orleans? Live Location can help you track down friends in the crowd. As the second-screen experience becomes more ingrained in live sports, Snap is making sure it’s front and center.

Snap’s New Initiative: The Department of Angels

Super Bowl Sunday is about competition, but what happens when the challenge isn’t on the field? Yesterday, Snap announced The Department of Angels, a new initiative aimed at supporting communities recovering from disasters, offering independent funding and resources to help them rebuild on their own terms. Backed by $10 million from Snap Inc., Evan Spiegel, Bobby Murphy, and the California Community Foundation, the program shifts away from traditional corporate donations and toward grassroots, community-led recovery efforts. Could this be a model for how tech companies engage with real-world crises in the future?

Apple Wants to Change How You Send Invites

Apple is stepping into the event invite space with Apple Invites, a new app designed to make organizing gatherings simpler. Competing with platforms like Partiful and Evite, Apple’s version integrates directly into iMessage and Apple Calendar, making it an easy, built-in option for Apple users. With so many invite platforms out there, will Apple’s streamlined approach become the go-to for iPhone users, or will it simply be another tool in the mix?

Where to Watch Super Bowl LIX

The Chiefs and Eagles face off this Sunday at 3:30 PM PT on FOX. Here’s a helpful link to directly access ways to watch. You can stream the game for free on Tubi, or catch it on YouTube TV, Hulu + Live TV, NFL+, and fuboTV. And of course, we’ll be watching to see which brands—including tech giants—deliver the most memorable ads of the night.

Between Snap’s game-day integrations, its push to support community-led recovery, and Apple’s move into digital invites, this week is full of shifts in how we connect. Which of these will redefine the way we interact? We’ll be watching.

Hello, Los Angeles!

This week, DeepSeekAI has been dominating the tech conversation. The Chinese AI startup’s chatbot app surged to the No. 1 spot on the App Store, drawing both excitement and scrutiny. Supporters see its open-weight model as a potential game-changer, offering developers more flexibility compared to closed AI systems like OpenAI’s. But the rapid rise has also raised questions about security, data governance, and global AI competition. Whether DeepSeek will be a long-term disruptor or just a momentary sensation remains to be seen, but one thing is clear—AI remains the tech industry’s driving force.

But while AI continues to dominate headlines, another sector is quietly making waves—defense technology. And one LA-based startup just secured a major endorsement from investors and the U.S. government.

Castelion’s Hypersonic Bet—Can It Outrun the Defense Industry’s Red Tape?

El Segundo-based Castelionjust raised$100 million to accelerate its mission to build hypersonic weapons faster, cheaper, and at scale. The financing—$70 million in equity (led by Lightspeed Venture Partners with participation from a16z, Lavrock Ventures, Cantos, First In, BlueYard Capital, and Interlagos) and $30 million in venture debt (from Silicon Valley Bank)—is the latest sign that venture capital sees national security startups as a high-growth opportunity.

Unlike traditional defense contractors, Castelion is operating like a fast-moving startup, not a slow-moving government supplier. Founded by former SpaceX engineers, the company is applying an iterative, test-heavy approach to building long-range hypersonic strike weapons—which travel at speeds exceeding Mach 5 (3,800+ mph) and are designed to evade modern missile defenses.

Not Just VC-Backed—The U.S. Military is Betting on Castelion Too

While the $100 million raise is a major milestone, Castelion already has funded contracts with the U.S. Navy, U.S. Air Force, and U.S. Army. These contracts are focused on hypersonic technology development and scaled manufacturing, areas where the military has struggled to move quickly due to bureaucratic delays and reliance on traditional defense giants.

To prove it can execute, Castelion recently successfully launched a low-cost ballistic missile from a self-built launcher in Mojave. Now, with both government contracts and venture capital behind it, the company is pushing forward on more flight tests and building out its scaled production capabilities.

With rising geopolitical tensions and an increasing focus on faster, cost-effective deterrence, Castelion is positioning itself as a new kind of defense player—one that moves at startup speed. Whether it can sustain that pace while navigating the complexities of government procurement remains to be seen, but one thing is clear: the future of defense tech isn’t just about who can build the best weapons—it’s about who can build them fast enough.

Hello, LA!

This week, tech headlines are buzzing with OpenAI's launch of Operator, a tool that promises to transform task automation, and TikTok’s major outage, which left millions disconnected. But closer to home, as wildfires blaze across Southern California, survival has become the focus—and technology is making it possible.

When the plume of smoke reappeared on the horizon, residents across Southern California turned to tools like Watch Duty. Over the past week, as flames surged, the app gained 600,000 new users in just one night, delivering critical, real-time information to help residents stay ahead of danger. Watch Duty, designed to provide wildfire updates, has proven to be much more than an alert system. It’s a lifeline.

The app integrates live data, satellite imagery, and community reports to send updates directly to users. Information includes fire locations, evacuation orders, and air quality indices, empowering quick, informed decisions. Its community-driven ethos—with contributions from locals, firefighters, and volunteers—ensures hyper-local and timely updates, filling gaps where traditional news outlets often fall short.

A Vision for the Future

As Los Angeles continues to adapt to the realities of a changing climate, tools like Watch Duty, Pano AI, and AlertCalifornia are proving to be invaluable. These technologies are not just reactive measures; they represent a shift toward proactive disaster preparedness. The question now isn’t whether technology can help but how much more it can achieve in the years to come.

With the integration of predictive modeling, AI, and real-time data, there’s hope for a future where wildfires are no longer unpredictable forces of destruction. Imagine every household equipped with predictive wildfire maps, heat-detecting drones, and AI-driven tools to guide safety decisions. The innovations are here—it's up to us to support and scale them to ensure they reach the communities that need them most. Which company, which app, or which breakthrough will emerge as the next lifeline? The possibilities for a safer, more prepared Los Angeles feel closer than ever.
