Garrett Langley, founder and CEO of Flock Safety, discusses building America's largest crime-fighting technology platform with John Collison of Stripe. Langley, an electrical engineer, started the company after a gun theft in his Atlanta neighborhood went unsolved by police.
The conversation covers Flock's evolution from neighborhood license plate readers to a comprehensive safety operating system deployed across 6,000+ American cities. Topics include real-time 911 integration, autonomous drone deployment, AI-powered crime analysis, and the challenges of building hardware for law enforcement.
Langley explains how Flock helped clear over one million crimes last year, the company's expansion into corporate security, and his vision for preventing crime rather than just solving it. The discussion also explores the complexities of selling to government agencies, hardware manufacturing at scale, and balancing public safety with civil liberties.
From Neighborhood Camera to Million-Crime Platform
Flock Safety originated when Garrett Langley built a camera to track cars after a gun theft in his Atlanta neighborhood went unsolved by police who "shrugged and left."
"In the southeast, if you pull 10 F-150 door handles, three out of 10 will be unlocked and one out of 10 will have a firearm in a glove box" - Garrett on opportunistic gun theft patterns.
The prototype camera tracked every car entering the neighborhood, allowing police to identify the only non-resident vehicle during the next theft, leading to arrest within hours.
Local news coverage became Flock's primary growth channel, with five neighborhood inquiries arriving after each crime story aired on the five o'clock news.
Real-Time Crime Operating System Architecture
Flock OS integrates all city cameras (Flock and third-party) with real-time 911 call analysis, allowing operators to dispatch resources and analyze incidents within minutes.
"We hear the 911 call in real time... imagine if you were running Stripe and every single lead you received was human routed. You'd say, this is crazy" - Garrett on 911 system inefficiencies.
Recent case example: attempted homicide with only "white Converse sneakers" as evidence was solved in 17 minutes using AI-powered video analysis across city camera network.
The system can automatically track armored cars and flag suspicious following behavior to prevent "jugging" crimes where shooters target money transport vehicles.
Autonomous Drone Deployment Revolution
Flock drones reach crime scenes in 68 seconds versus 7.5-minute average police response times, providing immediate aerial surveillance and tactical intelligence.
"Most of our towns that have adopted our drone program, they end pursuits. They don't pursue anymore" - Garrett on eliminating dangerous high-speed chases.
Drones can read license plates from nearly a mile away using multiple image sensors and optical lenses, with thermal capabilities for night operations and search-and-rescue.
Majority of 911 calls dispatched to drones "never need a human to show up," allowing officers to focus on genuine emergencies while drones handle routine calls.
Criminal Behavior Patterns and Technology Response
"South American cartels fly illegal drones through these neighborhoods. They'll flip on night vision, look through houses to see if anyone's home, then go break in" - Garrett on evolving criminal tactics.
Crime surged 3-4x during COVID, particularly among 16-22 year old males who were "very online," with violence escalating from social media disputes to shootings.
Organized retail crime has shifted from stores to distribution facilities, with sophisticated groups stealing $7 million in single-day operations using legitimate freight broker companies.
"Most people would intuitively say, oh, the punishment's really, really bad, people will do less of it... You operate on a Boolean mindset. I will get away with this" - Garrett on deterrence psychology.
Hardware Manufacturing at Government Scale
"I might be the largest general contractor in America. We pulled 77 permits a day last year" - Garrett on Flock's massive infrastructure deployment requiring hole-digging and concrete-pouring.
Hardware forecasting requires 12-18 month lead times with "every decision costing millions of dollars at minimum," making all choices "one-way doors" unlike software development.
Supply chain challenges include competing with Apple and Samsung for basic components like capacitors, requiring four different part derivatives for every component to avoid shortages.
One-third of Flock employees "dig holes for a living" as field technicians, with predictive maintenance replacing parts like IR cut filters after 100,000-200,000 mechanical cycles.
Corporate Security and Federal Coordination
Corporate business generates over $100 million annually, focusing on retail, healthcare, and logistics companies with large physical footprints and employee safety concerns.
Healthcare facilities face sophisticated theft operations where criminals pose as repair technicians to steal multi-million dollar surgical equipment for international resale.
Executive protection deployments can detect when the same vehicle visits both a CEO's home and corporate office on the same day, flagging potential surveillance threats.
Federal coordination remains controversial, with some states like California legislating against law enforcement collaboration with federal agencies despite major cases requiring multi-jurisdictional cooperation.
Future Vision: Crime Prevention Over Punishment
"Failure for Flock is prison population goes up" - Garrett on measuring success through crime prevention rather than arrests and incarceration.
Flock's Thriving Cities Fund deploys capital to create entry-level jobs in restaurants and nail salons, providing alternatives for at-risk youth in cities that adopt safety technology.
"The whole concept of prison will never work... putting a bunch of violent people together is by default flawed" - Garrett on seeking alternatives to incarceration for non-violent offenders.
Constitutional law team reviews all product development to ensure Fourth Amendment compliance, with drones programmed to point at horizon during transit rather than looking into private property.
