Berlin, 12 June 2026 - The international law firm ADVANT Beiten has provided comprehensive legal advice to the US venture capital investor Island Green Capital as new investor in the Series D1 funding round of the German aerospace company Isar Aerospace.
As part of the funding round, Isar Aerospace secured funding of up to EUR 270 million. In particular, the funding is intended to support the expansion of production capacities and the further scaling of launch vehicle production. The aim is to set up highly automated series production with a capacity of up to 40 Spectrum launch vehicles per year. In addition, the funding strengthens the development of independent European launch capacities for government and commercial satellite missions.
The capital increase was driven by strong interest from international investors. Previous funding rounds have already been supported by the NATO Innovation Fund, Eldridge Industries and Porsche SE, among others.
Island Green Capital (IGC) is a discrete, inflection focused venture capital firm that invests broadly across focus sectors for the US and Allied Nations. These include Aerospace & Defense, AI, Specialty Manufacturing & Robotics, Financial Services, and Software. With a flexible investment approach, IGC evaluates companies from Series A through pre-IPO. Aside from being true partners at the board and company level, IGC helps with the less visible but often critical work such as structuring non-dilutive debt, employee liquidity programs, and resolving cap table complexity. With its commitment to Isar Aerospace, its first in Germany, IGC underlines its interest in European technology leaders and the increasing importance of the space industry as a key sector for economic and geopolitical sovereignty.
ADVANT Beiten advised Island Green Capital on all legal aspects of the transaction, including the negotiation and review of the relevant transaction documentation as well as the structuring and implementation of the investment. The retention was based on the recommendation of the US law firm Massumi + Consoli, with which ADVANT Beiten advised on the transaction in close coordination. The successful cooperation underlines the law firm's international network as well as its special expertise in complex cross-border venture capital and growth funding. At the same time, the retention confirms ADVANT Beiten's strong position in advising international investors on investments in German and European technology companies, especially in innovation-driven industries of the future such as SpaceTech, DeepTech and DefenceTech.
