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."

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.

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

      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.

      Hermeus Moves In. Uber Lines Up. LA Wins.

      🔦 Spotlight

      Hello, Los Angeles.

      This week’s transportation news says a lot about where LA is headed and who wants to build here.

      Start with Hermeus, which hit a $1 billion valuation after raising $350 million as it works on high-speed aircraft for defense applications. More notably for Los Angeles, the company is moving its headquarters to El Segundo, adding to the region’s growing aerospace and defense cluster. The round was led by Khosla Ventures, with participation from returning backers including Canaan Partners, Founders Fund, RTX Ventures, Bling Capital, and In-Q-Tel, along with new investors including Cox Enterprises, Socium Ventures, Destiny Tech100, Georgia Tech Foundation, 137 Ventures, and GSBackers.

      Then there’s Uber, which made two separate autonomous vehicle announcements that both put Los Angeles in the rollout map.

      The first is a partnership with Zoox, Amazon’s autonomous vehicle company. Uber said the service is expected to launch in Las Vegas in summer 2026 and then come to Los Angeles by mid-2027, giving riders the option to match with a Zoox robotaxi through the Uber app.

      The second is a new deal with MOIA America, which plans to deploy autonomous ID. Buzz vehicles on the Uber platform in Los Angeles by the end of 2026.

      Taken together, the message is pretty straightforward: LA is not just watching the future of transportation take shape, it is increasingly being used as the place to test it, scale it, and sell it. Hermeus is bringing its headquarters here as defense aviation regains momentum. Uber is lining up autonomous partners with Los Angeles as a target market. Different companies, different timelines, same conclusion: a meaningful share of the next transportation cycle is being built with LA in mind.

      Below are this week’s venture deals, fund announcements, and acquisitions across LA.
