The shelf life of a thawed coronavirus vaccine is only a few hours, and expired vaccines have to be thrown out.

That inspired the New York-based startup Dr. B, the COVID-19 company meant to reduce vaccine waste created by ZocDoc cofounder Cyrus Massoumi. It's just arrived in Los Angeles, as the eligibility for vaccinations lifts next week.

Dr. B aims to reduce vaccine waste and the chaos that comes with it by matching vaccine providers with prospective patients within hours.

The company said it has secured three providers in the region so far.

To enroll in the waitlist, people have to sign up online at Dr. B's website and share certain health and geographic information to inform the site of local guidelines it needs to follow. When a free appointment pops up, one will receive a text notification. If they don't accept the appointment within a certain time frame, it gives the appointment to someone else.

Its test will come next week when anyone over the age of 16 can make an appointment.

Those using Dr. B would need to drop everything to travel to a vaccination site in a matter of hours. People with inflexible jobs or child care often don't have that luxury.

Already, a slew of community- and company-run sites are helping folks in L.A. find vaccine appointments, including Get Out the Shot and Find My Vax LA, run by recent college graduate Andrew Freidman. Health care startups like Carbon Health and Curative have made efforts to help people find vaccine appointments.

Dr. B's arrival also comes as the region's thinking on "cutting the line" for vaccine doses has shifted.

In February, when L.A. County began administering vaccines to health care workers those who lined up to see if they could score extra doses were often called "vaccine vultures" and chided on social media for not waiting in line.

But as more doses become available, the disdain some felt has faded, with the general consensus now shifting to use the vaccine, no matter what. L.A. County officials have urged health care workers to not throw away vaccines.

VC Giants Back LA Defense Tech Startup

VC Giants Back LA Defense Tech Startup

🔦 Spotlight

Hello Los Angeles, and happy Friday!

Memorial Day Weekend is finally here, and it seems even PCH got the memo, just in time for those coastal drives to kick off summer, traffic jams included. Speaking of navigation, El Segundo based startup CX2 has charted its own impressive course this week, securing $31 million in a Series A round led by Point72 Ventures, with participation from Andreessen Horowitz, 8VC, and Pax Ventures, to boost its mission in electronic warfare.

Electronic warfare (EW), for those of us who aren't regulars at the Pentagon, involves the tactical use of electromagnetic energy to control the spectrum, essentially jamming or confusing enemy communications and radar systems. CX2 was founded by a diverse and experienced group: Nathan Mintz, who brings deep expertise in defense technology from previous ventures such as Epirus and Spartan; Mark Trefgarne, a software entrepreneur known for a successful acquisition by Meta; Lee Thompson, an expert RF engineer previously with SpaceX; and Porter Smith, whose practical insights stem from his background as a U.S. Army helicopter pilot and subsequent experience as an investor.

The new funds will help CX2 scale its team and accelerate the development of advanced tools, including autonomous drones and specialized signals-intelligence systems. These innovations promise precision interference without collateral disruptions, addressing critical defense capability gaps identified by industry experts.

With tensions escalating globally, there's big demand for next-gen defense solutions, and CX2’s technology positions them as a major player in shaping future electronic battlespaces.

Dive deeper into the details and check out this week's roundup of LA’s venture deals and acquisitions below.

Here's to a weekend filled with sunshine, clear roads (fingers crossed), and tech that keeps pushing boundaries!

            Forget Traffic: Air Taxis Are Coming to LA28

            🔦 Spotlight

            Hello Los Angeles,

            The future just got a flight plan, and it includes skipping traffic for the 2028 Olympics.

            Image Source: Archer

            This week, Santa Clara-based Archer Aviation made headlines (and history) by being named the official air taxi provider for the LA28 Olympic and Paralympic Games and Team USA. Yes, that means electric vertical takeoff and landing (eVTOL) aircraft will be soaring above the gridlocked freeways, whisking athletes, officials, and perhaps a few lucky spectators through LA’s famously congested skies.

            This isn’t just a flashy PR stunt (although, let’s be honest, it is peak LA). It’s a strategic move to redefine how we move around the city, especially during one of the largest global events ever to hit Southern California. In partnership with the LA28 Organizing Committee, Archer plans to deploy its Midnight aircraft, an all-electric air taxi that promises ultra-quiet, zero-emission rides from point A to point OMG-I’m-not-in-traffic.

            While Archer is headquartered in Santa Clara, it has deep ties to the LA tech ecosystem. United Airlines, one of its major partners, has previously announced plans to establish eVTOL routes between downtown and LAX. Pair that with this new Olympic milestone and we’re looking at LA as ground zero for what could become the world’s first large-scale urban air mobility network.

            Of course, there are still regulatory hurdles, infrastructure needs, and airspace coordination issues to iron out before we can book our sky ride to the Coliseum. But make no mistake, this announcement is a moonshot moment for LA tech, mobility, and the future of Olympic-scale transportation.

            We’ll be keeping our feet on the ground (for now), but we’ll definitely be watching the skies.

            Catch you next week ✈️✨

                    This LA Startup Wants to Make It Rain and Just Raised $25M to Do It

                    🔦 Spotlight

                    Hello LA!

                    While most tech headlines are busy chasing AI chatbots and flying taxis, one startup in El Segundo is aiming a little higher. Literally.

                    Rainmaker just secured$25 million in Series A funding to expand its cloud-seeding drone technology. The round was led by Lowercarbon Capital, with participation from Starship Ventures, 1517 Fund, Long Journey Ventures, Naval Ravikant, and others.

                    Their idea is simple but urgent. Instead of relying on old-school aircraft to spray rain-making particles across the sky, Rainmaker uses AI-powered drones that find and seed clouds with pinpoint accuracy. It is faster, more affordable, and could reshape how regions fight back against droughts.

                    California's ongoing water struggles have made it clear that simply "saving" water is not enough. Cities and entire economies need new tools to create it. Rainmaker plans to use the funding to grow its fleet, invest in atmospheric science, and expand commercial partnerships with utilities and governments searching for solutions.

                    Bigger picture, Rainmaker is part of a growing shift in LA's tech ecosystem. While software remains dominant, more investors and founders are quietly betting on "hard tech" that addresses real-world problems like water, energy, and infrastructure.

                    It is not just about apps anymore. It is about survival tech.

                    With the skies getting hotter and the reservoirs getting lower, the next great tech export out of LA might not be entertainment or social media. It could be rain.
