In 1943, a 22-year-old math graduate from Glasgow walked through guarded gates into a low, humming hut that smelled of oil, wet wool, and hot metal.

Inside, rows of young women like her bent over endless streams of intercepted enemy messages that were never supposed to be read by her. Hour after hour, she searched for tiny glitches in seemingly random letters: an operator's bad habit, a repeated phrase, knowing the course of the world could be affected by her work.

Women codebreakers in World War II quietly turned the tide of the conflict by cracking German and Japanese military ciphers at places like Bletchley Park in Britain and Arlington Hall in the United States, where they made up the overwhelming majority of staff.

Working under strict secrecy, more than 10,000 women built pattern libraries, ran electro-mechanical machines, and pioneered large-scale signal analysis. While credit for victory often went to the men whose orders their intelligence enabled, their breakthroughs helped locate and sink the battleship Bismarck, destroy U-boat wolf packs in the Atlantic, and guide operations from the Battle of Matapan to the invasion of Normandy. They directly shortened the war and saved thousands of lives.

Their methods now sit at the foundation of modern cybersecurity. The same logic of exploiting weaknesses in "unbreakable" systems still governs how security teams think about encryption and attacks today. Bletchley-style habits—collecting huge volumes of traffic, hunting for recurring patterns and operator quirks, assuming no system is truly invulnerable—still echo in practices like traffic analysis, anomaly detection, and red-teaming.

The most interesting echoes of those women’s work may be less about stronger math and more about smarter humans.

There are two broad lessons for startup leaders

In technology, as AI automates routine detection, the edge shifts to what those codebreakers excelled at: cross-disciplinary intuition, spotting human error, and creatively stitching together small scraps of data into a clearer picture of risk.

Train yourself to be a generalist. Some ways to push your knowledge are reading well outside your field, inviting advisors from different industries into your orbit, and taking a class just for fun. Widen the pattern library in your own head. You'll be far more likely to see unexpected connections before anyone else does.

In leadership, your biggest unlock may come from elevating the overlooked people already in the room. Give your team problems, not just tasks, the way wartime commanders relied on hidden codebreakers to tilt the course of the war.

You don't have to rewrite anyone's job description. Start with "small codes to decipher" by finding discrete, surprising challenges at the edge of their role. Watch who leans in, who solves them, and who asks for the next puzzle. That curiosity may be the real key to your company's future.

This section, called Go Wide: A Life Less Curated, serves as an antidote to algorithms and echo chambers by revealing how major historical events impacted the world and might shape what comes next.
