In June 2025, Polaris Spaceplanes (Bremen, Germany) successfully secured an oversubscribed €5.3 million top-up funding on its recent seed round, bringing three new investors on board. The aerospace startup’s private funding now totals €12.4 million, complemented by customer contracts — which are at a total of €10 million so far.

This most recent funding round was co-led by Capnamic Ventures Bremen and Spacewalk VC, complemented by private investor Guiseppe Nardi. Three existing investors made a significant contribution to the round as well, including Dienes Holding and E2MC (Earth-to-Mars Capital) Ventures.

The new funding will be used to field Polaris’ first serial product, pre-fund upcoming new customer contracts and prepare for a large funding round in the coming months. Polaris is actively developing a new category of reusable spaceplanes that take off and land horizontally from airports, to offer more rapid turnaround, reduced cost and minimal ground infrastructure when compared to traditional vertical launch systems. The increasing importance of economic viability and sustainability, but also national sovereignty, the company points out, make horizontal takeoff spaceplanes the solution of the future for access to space and hypersonic flight.

Polaris’ roadmap targets a light spaceplane by 2027 and a heavy vehicle by the early 2030s. To do this, the company is developing scaled flight demonstrators including MIRA and now MIRA-II (VCN-007) and MIRA-III (VCN-008), all featuring an airframe made using glass fiber-reinforced composite sandwich construction.
