The Rise of Defense Start-Ups in Europe: Eric Slesinger's Venture
Eric Slesinger leverages his CIA background to champion European defense technologies amid rising military budgets.
During a recent visit to Copenhagen, Eric Slesinger met with key figures in the defense sector, including engineers developing advanced maritime drones and architects of critical war-planning software. Once a Central Intelligence Agency officer, the 35-year-old venture capitalist is now at the forefront of European defense investments with his firm, 201 Ventures. Slesinger's career shift coincided with a significant increase in European military spending, spurred by growing uncertainties about trans-Atlantic relations.
With European governments planning to allocate hundreds of billions of euros for military enhancements—ranging from cutting-edge weapons to missile-defense programs—entrepreneurs and investors are racing against time to tap into this burgeoning market. Slesinger has already backed eight defense start-ups and is actively negotiating with others in this rapidly evolving field.
Years ago, when he relocated to Madrid, Slesinger’s foresight about the continent's pressing defense needs was largely ignored. However, the current geopolitical climate has validated his predictions. President Trump’s administration had a significant impact on European perceptions of U.S. military support, with harsh words directed at allied nations that were deemed overly reliant on American defense.
Among the promising European start-ups in his portfolio is Delian, a Greek firm specializing in fixed surveillance towers designed to safeguard coastlines and crucial infrastructures. As the international landscape shifts, Slesinger is positioned to play a vital role in shaping Europe’s defense technology future, ensuring it's prepared for the challenges that lie ahead.
