Data Library as a Competitive Moat

We’re excited to launch a very special edition of Valley of Depth, recorded live from the historic vault deep beneath the New York Stock Exchange (NYSE). Going forward, we’ll be returning to the NYSE each month to host a series of conversations from the heart of global capital markets with the leaders building the next generation of critical infrastructure.

In this installment, we sit down with John Serafini, CEO of Hawkeye 360, a company quietly reshaping how governments see and understand the world. While many space companies focus on imagery or communications, Hawkeye 360 is doing something different: listening. By mapping radio-frequency emissions from orbit, the company is turning invisible signals into actionable intelligence, revealing patterns of human behavior that imagery alone can’t capture.

We discuss:

• How space-based RF mapping changes what “global transparency” actually means
• Why signals intelligence is uniquely tied to human activity and intent
• How Hawkeye’s multi-satellite architecture enables precise geolocation at scale
• What it takes to detect dark vessels, GPS jamming, and spoofing in near real time
• Why RF data, software, and proprietary signal libraries form a durable competitive moat
• How commercial SIGINT is becoming core infrastructure for governments globally
