Coronavirus 'Came Here on an Airplane' and GermFalcon Promises to Stop it in the Sky

Seven years ago, Elliot Kreitenberg and his father, orthopedic surgeon Arthur Kreitnberg, built a UV-C light machine called GermFalcon to kill viruses on planes, but the airline industry largely rejected their pitch.

Years later with coronavirus all but wiping out air travel, their machine is looking a lot more attractive.

The founders of Long Beach-based Dimer UVC Innovations are in talks with airlines, transit authorities and others desperate to disinfect airplanes, subways and other transportation vehicles where COVID-19 quickly travels.


"We are in serious discussions with U.S. airlines as well as ground service providers, as well as international airlines in Canada, Europe and Southeast Asia," Elliot Kreitenberg said. The company is also talking to several transit authorities about manufacturing their product for them, although he could not reveal the names of anyone due to non-disclosure agreements.

Artificially produced UV-C is a common method of sterilization used in hospitals or to clean drinking water, but it hasn't been widely adopted to fight the virus in transportation. That's in part because studies haven't caught up to prove it works, although the light has been shown to be effective against other coronaviruses.

But, in China, busses have been blasted with the blue UV-C rays in an effort to fight the pandemic.

The Environmental Protection Agency and the Centers for Disease Control and Prevention are looking at UV light as a solution for large-scale disinfecting in places like schools and offices. And it's attracted the interest of other government agencies, including the Los Angeles County Metropolitan Transit Authority, which is considering using UVC light to clean its fleet of busses and trains.

"We're already increasing the frequency of our cleanings and we are doing more deep cleaning," said Jesus Montes, an executive at L.A. Metro's vehicle acquisition and engineering department. "To supplement that, we're looking to things such as foggers and vaporizers and UV."

Montes has been inviting UV vendors to demonstrate their products. The advantage he's found over vapors or foggers, which can cause damage to the electrical engines, is that UV rays are far less labor intensive and can be used off site.

Other companies that supply the light to hospitals have seen an uptick in sales. Kreitenberg said they have also been getting orders and expect to have up to 100 of their UV machine made for hospitals finished by mid-May. From there, they will go into production of 10 a day. He said he's already provided Paine Field Airport with a machine that's now in use. And his machine was cleaning airplanes at Los Angeles Airport that had been in-bound from China when travel had not been restricted.

Dimer keeps its rays to surfaces, where it says it can kill up to 99.9% of bacteria.

"What's nice about this technology is that it's not going to promote resistance to anti-microbial agents," said Leonard Mermel, a professor at Brown University and the medical director of Rhode Island Hospital's Department of Epidemiology and Infection Control who is familiar with the technology.

Airplanes are particularly tricky because microbes can potentially survive longer.

"We know some viruses can survive certainly overnight...cooler temperatures and the dryness of airplanes actually improves survival of some viruses like flu."

Other companies offer UV lighting. But what makes Dimer's $100,000 disinfectant machine different than others that attacks microorganisms, bacterias and superbug is that it's made for airplanes. Amortized over a conservative 5-year lifespan, the machine costs 10¢ per passenger.

About the width of a drink cart, the machine slides easily down an airplane aisle and has a winglike feature that spreads the light over seating. He's also making another product that's geared toward hospitals and space that aren't as tight.

A few years ago, he said he brokered a deal with Virgin America to use the GermFalcon, but it went belly up when Alaska Air Group bought the company for $2.6 billion.

Arthur Kreinberg, who is also the co-founder of the company, became familiar with the lights through his experience with them in hospitals. He then worked with his son to build their first designs in their garage.

"(My paternal grandfather) was a Holocaust survivor and plumber and when my father graduated from medical school he said 'plumbers save more lives than doctors because sanitation plays a big role in public health.' When the toilet was invented it doubled human life expectancy. I think GermFalcon is the most important invention since the toilet."

The World Health Organization considers those that are in contact with an individual infected on a flight and those sitting within two rows at most risk. But, airplanes have a reputation as vectors of germs.

Elliot Kreitenberg, once a frequent flier, said he's been keeping a log every time he travels of the dirtiest places on the airplane. It's not the toilet handle but, according to his own informal survey, the back of head rests where people touch as they walk down the aisle.

"Airlines play a direct role in the way that disease spreads around the world," Elliot Kreitenberg said. "We see that here with coronavirus. It flew here on airplane."

Match Goes Niche With $100M Move

🔦 Spotlight

Hello Los Angeles,

It’s May, and LA is about to have one of its more important weeks.

The Milken Institute Global Conference 2026 returns to Beverly Hills next week, bringing together thousands of investors, operators, policymakers, and executives. It’s one of the few places where public markets, private capital, and tech actually overlap in the same rooms, and where you can usually get an early read on what capital is leaning into before it fully shows up in the data.

This year, one theme is already starting to surface. Platforms are getting more specific, not more broad.

This week’s news is a good example.

Match Group is investing $100 million into Sniffies, a fast-growing, location-based platform built for gay, bi, trans, and queer men. It’s a notable move for a company best known for mainstream dating apps like Tinder and Hinge, and it signals a deeper push into more niche, community-driven platforms.

Sniffies operates very differently from traditional dating apps. It’s more real-time, more map-based, and more focused on immediacy than long-term matching. In other words, it’s built around behavior, not profiles.

And that’s what makes the investment interesting.

For years, the dominant strategy in consumer platforms was scale, build one product that works for everyone. But what we’re seeing now is the opposite. The platforms that are gaining traction tend to be the ones that understand a specific audience deeply and build for how that group actually behaves.

Match leaning into that shift isn’t just about expanding its portfolio. It’s a recognition that growth is coming from focus.

And in a city like Los Angeles, that’s usually where things start.

Below are this week’s venture deals and fund announcements across LA 👇

      Netflix Doubles Down on LA

      🔦 Spotlight

      Hey Los Angeles.

      Goodbye Coachella, hello Stagecoach. The desert doesn’t stay quiet for long, and neither does LA’s entertainment machine.

      This week, that momentum showed up in a more permanent way.

      Netflix is expanding its footprint in Los Angeles with a major move to take over and invest in Radford Studio Center, a historic production lot in Studio City. The company is planning a long-term transformation of the site, with upgrades to soundstages, production offices, and infrastructure designed to support the next generation of film and television production.

      It’s a notable shift in a moment when production has been under pressure in California, with studios increasingly looking outside the state for cost advantages. Netflix going deeper in LA, and specifically into a legacy studio lot, signals a different kind of commitment. Not just to content, but to where that content actually gets made.

      And it comes at a time when the streaming wars have matured. Growth is harder, budgets are tighter, and the focus has shifted from scale at all costs to efficiency and control. Owning or operating more of the production environment gives Netflix tighter control over timelines, costs, and output.

      For Los Angeles, it’s a reminder of what still anchors the city. Even as AI, defense tech, and infrastructure startups continue to rise, entertainment remains one of the few industries where LA isn’t just competitive, it’s foundational.

      Different headlines each week, but a consistent theme underneath them. Whether it’s power, autonomy, or content, the companies that matter are investing in the layers they don’t want to outsource.

      And in this case, that layer is Hollywood itself.

          A $26M Push Into Power in LA

          🔦 Spotlight

          Hello, Los Angeles.

          Coachella Weekend 2 is here, which usually means LA is either heading back to the desert or happily staying put this time around. Back in the city, the focus this week is less about music infrastructure and more about something far more critical, power.

          That’s where this week’s news comes in.

          Critical Loop, a Los Angeles-based energy startup, raised a $26 million Series A to tackle one of the least talked about bottlenecks in tech right now, grid interconnection. In simple terms, it’s the process of getting power to where it’s needed, and increasingly, that process is too slow to keep up.

          Critical Loop is building modular microgrid systems that can be deployed in days instead of years, giving industrial operators, data centers, and other energy-heavy users faster access to power without waiting on traditional grid upgrades. The round was led by Conifer Infrastructure Partners and Hanover, with participation from Better Ventures, Climate Capital, Adapt Nation Capital, and Cyrus Ventures.

          The timing here matters. Between AI infrastructure demands, electrification, and a broader push toward domestic energy resilience, power is quickly becoming a gating factor for growth. You can build the data center, the factory, or the next big thing, but none of it works if you can’t turn it on.

          That’s what makes companies like Critical Loop worth watching. They’re not building the flashiest part of the stack, but they’re solving for the piece everything else depends on.

          And in a city that knows a thing or two about scaling ambition quickly, that might be the most important layer of all.
