The Spark

Brett Adcock became obsessed with the exponential rise in K-12 school shootings in America after analyzing the data. Over the last seven years, school shootings had increased roughly 10x, with several hundred thousand guns being brought into schools annually. Unlike the high-profile mass shooting narratives, Adcock discovered that 98% of school shootings involved a student bringing a handgun as "an accessory" in their backpack, getting into a fight, and escalating to violence. He realized the solution wasn't just gun control—it was detection.

Building the First Version

While reading research papers as a hobby, Adcock discovered a 2013 NASA Jet Propulsion Lab project that had developed high-frequency radar technology for detecting bomb vests and weapons through garments in conflict zones like Afghanistan and Iraq. He cold-called the researcher who led the project, flew to Pasadena, and was given a basement demo of the dusty, dated machine. When the scientist turned it on and showed him a mannequin with a hidden gun, Adcock saw a camera-like image of the weapon reconstructed via radio frequency—essentially a 3D point cloud. He was hooked.

An investor coincidentally brought the problem to Adcock's attention in 2023 while he was working on Figure (his humanoid robotics company). The investor asked: "As somebody with kids, how are you not trying to make this work?" Adcock decided to pursue it. Within months, Cover was formed with about 12 people, all intellectual property licensed from JPL, and a first system scheduled to be operational within 30 days.

What Worked (and What Didn't)

Adcock's cold-call strategy worked because he was genuinely passionate about the JPL researcher's decade-old work and articulated that clearly. Most people will take a call from someone who has read their research and cares deeply about it. However, Adcock is candid that schools are actually "the worst market" for fundraising—they have tiny budgets and don't allocate capital for security systems like this. The real money, he acknowledges, is in stadiums, hospitals, airports, and concert venues with serious security budgets and existing security infrastructure (metal detectors, TSA PreCheck, Homeland Security contracts).

Where They Are Now

Cover is pre-revenue and pre-announcement (the interview represents the first public discussion). Adcock is funding it as a passion project and hasn't decided whether to raise outside capital. He explicitly states he doesn't care about the business model or investor pitches—he's building it to solve K-12 school shootings, not to maximize returns. The first operational system is being set up to begin imaging weapons. Adcock's philosophy on the longer-term vision is that longevity increases risk aversion; as humans live longer, they'll demand ubiquitous safety systems like this in stadiums, churches, hospitals, and public spaces—creating a massive multi-billion-dollar TAM, even if schools alone don't justify the business case.

Why It Worked
  • Adcock identified a specific, data-driven problem (98% of school shootings involve handguns as accessories) rather than chasing the narrative around mass shootings, which allowed him to focus on a solvable detection problem instead of broader policy debates.
  • He leveraged existing, proven technology from a credible institution (NASA JPL) rather than building detection from scratch, dramatically reducing technical risk and development time to 30 days for a working system.
  • His genuine passion for the researcher's work and clear articulation of that passion made cold outreach successful, demonstrating that authentic interest in someone's research opens doors that generic pitches cannot.
  • He maintained mission clarity by explicitly rejecting optimization for investor returns or business model fit, which freed him to build for the actual problem rather than constraining the solution to fit a fundraising narrative.
How to Replicate
  • 1.Deeply research and read existing work in your problem domain, then cold-call the researchers or practitioners whose work resonates with you—articulate specifically what you learned from their work and why it matters to you.
  • 2.Identify whether your initial target market (schools) has the budget and infrastructure for your solution, and if not, map adjacent markets (stadiums, airports, hospitals) that have existing security budgets and procurement processes you can leverage.
  • 3.License or partner with existing proven technology from credible institutions rather than building core functionality from scratch, even if it requires negotiation or relocation—this collapses your time to prototype.
  • 4.Separate your personal mission from your business model decisions; build the solution that solves the problem you care about first, and only then decide whether to commercialize it or how to fund it, rather than forcing the problem to fit a venture narrative.
