For almost two years, Viktor Makarskyy has been working on an app that serves as a digital survival kit to help people in disaster zones, which are getting more numerous seemingly by the day given the pace of climate change.
He never imagined his work and personal life would collide in such a profound way.
On Wednesday night, Makarskyy was flying home to Los Angeles from an anniversary trip with his wife in the Cascade Mountains, in the Pacific Northwest. An evacuation order for the Sunset Fire had already been issued extending to just a few blocks from their apartment.
Makarskyy was terrified that the fire would reach their home before they could rescue their cat and collect critical belongings.
“It’s one thing to see pictures online,” Makarskyy told CNBC in an interview Friday, “it’s another thing to see it out the plane window and to have this multisensory experience of your cabin smelling like smoke as you land. It was like entering a war zone.”
Makarskyy is the head of technology at GOES, a startup founded in 2021 with a focus on providing critical health advice and services, mostly in remote areas. Aid workers and intrepid travelers can download the GOES Health app and get quick localized tips on how to deal with bug and animal bites, altitude illnesses, rashes and a host of other challenges.
Hikers can gauge hypothermia risk, and backpackers can plan out how to prepare for a heat wave or look up how to temporarily set a broken bone. All content is written or approved by wilderness medicine doctors, and everything can be accessed offline other than real-time weather and the app’s wildlife risk index.
Increasingly, GOES, which stands for Global Outdoor Emergency Support, is becoming relevant in a much more widespread way, as people in urban environments have to deal with sudden disaster due to hurricanes, tornadoes and catastrophic fires. Since Jan. 6, a day before the LA fires broke out, GOES has seen about an 800% spike in usage in the area, and over the past two weeks the number of new users in California has tripled, the company said.
As of Monday, the massive blazes across LA had killed at least 24 people, obliterated whole neighborhoods and burned thousands of homes and structures. No cause has been identified for the largest fires.

Makarskyy said he uses GOES to check air quality, national alerts, wildfire preparedness guides and more. Back at home, he said, he was surprised to see that although one of the most widely used weather apps showed the air quality around Los Angeles International Airport to be “moderate,” when he viewed a hyperlocal, more precise air quality measurement using GOES, it showed the air quality to be much worse.
“As the developer of this app, I knew it offered exact latitude and longitude,” he said.
GOES is far from alone in seeing a spike in usage due to the rise in disasters. The Watch Duty app, founded in 2021 and developed by a nonprofit group, has become practically ubiquitous in the LA area since the fires erupted. It was the top free app on iOS for much of last week and was still in the top five on Monday, providing LA residents with a precise reading on where fires are burning and spreading, which neighborhoods are in evacuation zones and the location of power outages.
In a post on X on Friday, Watch Duty wrote, “Our systems remain 100% operational while our radio operators sleep in shifts and our engineers are throwing everything they have at it to sustain up to 100,000 requests per second with an average response time of <20 ms.”
Watch Duty was developed by firefighters, dispatchers and first responders specifically to disseminate information related to fires. GOES, by contrast, stumbled into the fire safety market.
According to the GOES app’s launch announcement in 2023, Dr. Grant Lipman, a former professor at Stanford Emergency Medicine and director of its wilderness medicine fellowship, started the company “after treating a hiker in critical condition due to a rattlesnake bite” and seeing the need “to make wilderness medicine more accessible.”
‘The outdoors is changing’
GOES co-founder and CEO Camilo Barcenas spent years in the health-care space and worked for four years overseeing technology at the Stanford Adult Hospital. In 2019, he and his team began working on the GOES project, interviewing people in North America, South America, Asia, Europe and the Middle East about what would have made them feel safer and more prepared when traveling off the grid.
Their realization, he said, was that health care was “so broken systematically,” that the only way to improve is if people learn to take care of themselves first.
“We made this because we believe everyone should have this,” Barcenas said. “The outdoors is changing, and we need to be able to understand what these risks are so we can do better.”
Barcenas said that when Hurricane Helene hit North Carolina in September, he flew in to inform residents and aid groups about how they can use the platform. It’s become increasingly clear, he said, how useful the app can be when climate disasters strike.
“The LA wildfires highlight an acceleration of what we’ve been tracking: the democratization of wilderness medicine for urban survival,” Barcenas said. “When environmental emergencies strike, traditional emergency services and health-care facilities often become overwhelmed or inaccessible.”
Firefighters continue their work in the burning residential areas as wildfires continue to wreak havoc, reaching their fifth day and leaving extensive damage in residential areas in Los Angeles, California, United States on January 12, 2025.

Before arriving back in LA, Makarskyy said, he prepared for his return by checking national alerts within GOES, such as high-wind advisories, air quality and the location of wildfires. Each alert came with access to content written by wilderness medicine doctors on preparation and mitigation techniques.
He read up on “what to do in breathing problem scenarios” related to those alerts. He said he learned that N95 masks are “the only thing that can protect against particulates that are that fine, that small.”
“So rather than buying common surgical masks,” Makarskyy said, “I went ahead and bought the right product for us to keep our lungs safe in this environment.”
Makarskyy said he and his wife were fortunate not to have to evacuate. The fires were far enough away that they were safe but close enough that on Friday morning they woke up to ash coating their car. The closest fire had been contained. Their cat was safe with them.
The GOES app has some features that are free. Users can check on air quality and sunburn risk in their location and see if there’s any extreme weather advisory. For premium access, which includes pocket safety guide information, subscribers pay $6 a month or $36 a year.
Barcenas said there are a lot of new features on the way and that the app has already evolved significantly since launching less than two years ago.
“GOES was originally developed for outdoor adventurers to prepare for trips and manage wilderness medical emergencies with offline, visual first-aid guides,” Barcenas said. “Now, we’re seeing urban residents using it to understand their outdoor health risks and navigating emergencies during environmental crises.”

Tesla is set to report first-quarter earnings on Tuesday after market close.
Here’s what Wall Street is expecting, based on a survey of analysts by LSEG:
- Earnings per share: 39 cents
- Revenue: $21.11 billion
Tesla is expected to report a slight revenue decline from $21.3 billion in the same quarter a year earlier. However, investors are going to be more focused on what the future holds after concerns about tariffs and CEO Elon Musk’s close ties to the White House pushed the stock price down 44% so far this year as of Monday’s close.
Earlier this month, Tesla reported a 13% decline in deliveries to 336,681. Tesla blamed the lower deliveries, in part, on the need to suspend production temporarily at its factories while it upgraded lines to start manufacturing a refreshed version of its popular Model Y electric SUVs.
Deliveries are the closest approximation of vehicle sales reported by Tesla but are not precisely defined in the company’s shareholder communications.
At an all-hands meeting with employees last month, Musk tried to reassure staffers that they were still in good hands, and to “hang onto your stock.” He pointed to the popularity of the Model Y, and Tesla’s potential in robotics, artificial intelligence and autonomous vehicle technology.
At the meeting, Musk also made light of the backlash against Tesla elicited by his work for President Donald Trump to reduce the size of the federal government, and his endorsements of Germany’s anti-immigrant AfD party, along with other political rhetoric and antics.
“If you read the news it feels like, you know, Armageddon,” Musk said on a livestream of the employees meeting. “It’s like, I can’t walk past the TV without seeing a Tesla on fire.” He followed up saying, “This is psycho, stop being psycho!”
That was before Trump’s announcement earlier this month of widespread tariffs, the one area where Musk has publicly broken with the Trump administration. On X, he called Peter Navarro, Trump’s top trade advisor and tariff proponent, a “moron” and “dumber than a sack of bricks.”
Tesla stands to take a significant hit from the president’s proposed tariffs, assuming they don’t get rolled back. Tesla manufactures cars in the U.S. for domestic sales so it’s not subject to the 25% tariff on imported autos, but the hefty levies on other components and materials could be severe.
Tesla relies on suppliers in Mexico and China for items like automotive glass, printed circuit boards and battery cells, among other parts essential for the production of its cars. The company has sought an exemption from the U.S. trade representative for equipment imported from China that it uses in its factories.
