Inevitable (An MCJ Podcast)

Episode: Building a Real-Time Wildfire Alert Platform with Watch Duty

Guest: John Mills, Co-founder & CEO of WatchDuty
Host: Cody Simms
Release Date: April 3, 2025

Overview

This episode dives into the story behind WatchDuty, the nonprofit wildfire alert app that skyrocketed to #1 in the App Store during the recent Palisades and Eaton fires in Los Angeles. Host Cody Simms speaks with John Mills, the company’s co-founder and CEO, about the platform’s origins, its operational model, the harrowing days during California fire emergencies, and how WatchDuty is redefining public safety communications for wildfires and other disasters. Mills shares his personal journey from Silicon Valley engineer to off-the-grid community member and accidental leader in disaster tech, emphasizing a service-first philosophy and innovative nonprofit structure.

Key Discussion Points & Insights

How WatchDuty Works & Its Impact

• WatchDuty is a real-time, geospatial emergency alert platform for wildfires: Combining first responder radio analysis, mapping, and curated updates, it offers life-saving, timely information when traditional sources fail.
• It originated from the “Fire Twitter” community but added mapping and app-based push notifications for accessibility and reliability.
• The platform is operated primarily by volunteers and a small staff (200 volunteers to 15+ paid staff), leveraging crowd-sourced intelligence and a robust, scalable tech stack.

“If you've been through fire before, you know that information is very sparse and hard to find—especially during the first 24 to 72 hours. So we do real-time alerting from radio traffic of first responders fighting the fire. And that's how we do what we do so fast.”
—John Mills (04:28)

Addressing Critical Gaps during Major Fires

• During the January LA fires, WatchDuty became a vital resource—handling millions of users and immense server loads seamlessly.
• First responder and public trust has grown, though skepticism from agencies was an initial barrier.

“At peak, we were doing about a million active users every 30 minutes… The reporters, man, those men and women are sleeping in shifts. We’re door-dashing food. We're making them stop to take a break. It was really harrowing.”
—John Mills (12:49)

Handling Information and Human Factors

• The platform places strong emphasis on editorial restraint and accuracy, not just speed—reporting only verified, directly sourced information.
• Volunteers and staff undergo a rigorous progression and training for responsible reporting.

“We often remind people that we're quick, we're not hasty… People often tell me I'm going to lose my job soon and AI is going to take over. And A, I welcome it if they're going to solve it, but B, that's just not what's going to happen. It's too complicated. It's extraordinarily multimodal.”
—John Mills (17:26)

• AI is used to sift signal from noise, but human editorial oversight remains essential for critical, nuanced decisions.

Origins & Personal Motivation

• John Mills describes his transition from a tech founder in San Francisco to a rural Sonoma County resident, facing wildfires firsthand and realizing the information void experienced by residents.
• WatchDuty was incubated through deep personal experience, community immersion, and observing the “cow paths” created by people sharing information in informal ways.

“It matters to the people there. Even if it’s a hundred-acre fire, there could be seven houses there… What WatchDuty does well is de-escalate incidents as well… A little bit of information goes a long way. No information makes people freak out.”
—John Mills (24:19)

• Instead of imposing a product, Mills immersed himself in the ecosystem—volunteering, joining preparedness groups, and seeking to truly understand the pain points before building a solution.

Nonprofit Structure & Philosophy

• Intentional nonprofit from inception: Mills wanted WatchDuty to be structurally committed as a public service, not profit-driven or ad-supported.
• Transparent financials, heavy reliance on in-kind donations from tech partners, and community fundraising sustain operations.
• Memberships and donations (often $25 per user/year) constitute most funding, supplemented by grants (e.g. $2M from google.org) and now a “Pro” paid version sold to first responders and utilities.

“It feels a horrible thing to do to try and profiteer off of [disasters]… This is people’s misery—and my own too. It’s important that this stays ad free, sponsor free, no login, no email, no tracking, no nothing. Just works.”
—John Mills (35:09)

Lessons in Tech & Disaster Response

• WatchDuty’s tech is built for resilience, edge caching, and scalability (drawing inspiration from, but improving upon, the failings of early social media platforms during surges).
• Mills challenges assumptions about nonprofit constraints, describing European models (like IKEA, Bosch) and envisioning a world where mission-driven orgs can also pay top talent.

“There’s so much unlearning I had to do leaving Silicon Valley… The nonprofit industrial complex has such a bad rap… But ultimately, we’re changing the nonprofit model so we can attract the best talent in the world to solve a really complicated problem.”
—John Mills (39:52)

Vision for the Future

• WatchDuty will expand beyond wildfires—into other disaster areas (floods, earthquakes, tornadoes, hurricanes), aiming to build a unified “disaster intelligence platform.”
• Selling Pro services to agencies, utilities, and enterprise customers will continue to subsidize the free public service.

“Fire isn’t in the name on purpose. It’s about citizens on watch duty watching over their community… I want one app that does this for all disasters.”
—John Mills (46:09)

• The broader mission is also educational: creating a preparedness database (a Wikipedia for disaster resilience) and surfacing best practices to communities.

“Now that we have all this attention—eyeball time—we want to use that to our advantage, and the advantage of the community, and help them prepare and change to the world we’re living in now.”
—John Mills (48:05)

Trust, Government, and Public Service

• WatchDuty ultimately became widely used by first responders themselves, sometimes preferred over government dashboards due to ease of use and reliability of public-data aggregation.
• Mills sees working ahead of, and sometimes independent from, slow-moving government contractors as both a responsibility and a challenge—but stresses the importance of humility, empathy, and persistence.

“The misnomer is that it’s our data… It’s the American people’s data. Which means it’s free for all—we all pay for it… It is our pleasure to repackage it and give it back as something better.”
—John Mills (51:08)

Notable Quotes & Memorable Moments

• “We knew who we were when we started. Twitter did not. We knew the traffic patterns, we knew there’d be peaks and spikes. We built a lot of architecture around that idea.”
  —John Mills (19:40)

• “If I asked for permission, I would not be here today. So you gotta be empathetic and a little bullheaded at the same time.”
  —John Mills (57:42)

• “I used to work in homelessness a little bit… Coming into a problem and saying I’m going to go solve fire is like saying I’m going to go solve homelessness. It just has no bearing in reality. So really living with these people… and aligning your skill set to what you can actually do.”
  —John Mills (60:07)

• “Wildfire comes from wildland fire… And living out here on hundreds of acres with really no neighbors and being in this forest has really changed my perspective.”
  —John Mills (63:16)
