Isar Aerospace

Isar Aerospace was founded in 2018 by Daniel Metzler, Josef Fleischmann and Markus Brandl and is based in Vaterstetten, near Munich, Germany. It designs, builds and launches Spectrum, a two-stage rocket for small and medium satellites, and earns revenue by selling dedicated, lead-payload and rideshare launches to commercial and institutional customers. Spectrum's maiden flight, on March 30, 2025, from Andøya Spaceport in Norway, was terminated about 30 seconds after liftoff when a vent valve opened unexpectedly. The second flight, on Sept. 5, 2026, reached orbit and released five CubeSats and a Dcubed technology demonstration. The company employs more than 400 people in five countries. In June 2026 it raised a €270 million Series D from new investors Island Green Capital and Molten Ventures and existing backers including HV Capital, Lakestar and UVC Partners, to fund serial production of Spectrum and new launch sites.
