Greek Defense Startup Delian Alliance Raises $14M to Revolutionize European Military Tech
  • Delian Alliance Industries, a Greek defense tech startup founded by former Apple roboticist Dimitrios Kottas, has successfully raised $14 million in a Series A funding round, bringing its total funding to $22 million.

  • After leaving Apple's Special Projects Group in 2021, Kottas returned to Athens to establish Delian, focusing on advanced surveillance and autonomous systems to strengthen the European defense industry.

  • Delian is entering a competitive defense sector marked by increased military spending in Europe, where it aims to compete against established firms like BAE Systems and emerging companies like Helsing.

  • The startup employs Silicon Valley business strategies and vertical integration to streamline its supply chain, allowing for quicker delivery times and lower costs for its aerial and sea-based drones.

  • Unlike traditional European defense firms that rely on complex supply chains, Delian manufactures its hardware and develops its software and sensor systems in-house, fostering faster innovation.

  • The recent funding will be utilized to enhance Delian's product offerings and support further development of its technology solutions, including advanced maritime drone technology.

  • Delian focuses on delivering drone technology to countries lacking their own programs, capitalizing on the demand for affordable and effective defense solutions.

  • The Series A funding was co-led by Air Street Capital and Marathon Venture Capital, with contributions from several other investors, reflecting growing interest in defense technology startups.

  • Kottas believes that innovative startups like Delian can penetrate the fragmented European defense market, despite challenges posed by U.S. pressure on European countries to purchase American weapons.

  • Emphasizing the urgency of their mission, Kottas stated that adversaries are rapidly adopting emerging technologies, necessitating military deployments that should be measured in days rather than decades.

  • Kottas' background includes recognized research on GPS-denied navigation and extensive experience in autonomous systems at Apple, which informs Delian's technology development.
