Signal from the defense-tech frontier.

Data-driven reports on the companies, capital, contracts, technology, and talent shaping defense tech — from the team that recruits inside it.

One Chart · Founder Networks

A founder’s rolodex lasts about two years.

Across 81 defense tech companies founded since 2023, up to a third of first-year hires had already worked alongside a founder — same employer, overlapping dates. By year four it is about one in thirty. Roughly twelve times what chance would produce. These 81 companies only, not a sector wide sample.

Issue 04 · Defense Tech Hiring Pulse

At the 75 companies we tracked, half of all open roles vanish in seven weeks.

Every open role at 75 defense and national security companies, pulled straight from their applicant tracking systems. Half of a given week’s postings are gone within seven weeks, only 18.9% of new roles are software, and 58% name no clearance at all. These 75 employers only, not a sector wide sample.

Issue 03 · Defense-Tech Market Signals

Most defense-tech “markets” are three companies and a long tail.

We tracked $34.3B of venture equity into 395 defense-tech companies over two years and split it by what those companies build. In six of ten domains, three companies hold roughly 90% of all capital raised. In five, a single company holds more than 70%. Space and aerospace is the only domain where capital is genuinely distributed, and it is also the largest.

Issue 02 · Defense-Tech Talent Migration

Where defense tech gets its hardware engineers.

We traced 2,751 hardware-engineering hires at 35 defense-tech manufacturers over the trailing 12 months, adjusting for company size to find who actually feeds hardware talent. Commercial-space firms like Vast and Rocket Lab over-index by roughly 22 to 38 times their size; the legacy primes split; Big Tech barely registers. Every feeder figure carries its observed hire count and a 95% interval.

Issue 01 · Defense-Tech Talent Migration

Where defense tech's software engineers really come from.

We traced 956 software hires at nine of defense tech's fastest-hiring names — Anduril, Palantir, ICEYE and more — adjusting for company size to find who really over-indexes as a feeder. Amazon does; the legacy primes split unevenly, and about 1 in 5 hires already did a defense tour.
