Huge congratulations to Quantum Systems on their $1.2Bn Series D at an $8Bn valuation.

We led Quantum Systems' Series B in September 2024, backing Florian and the team's vision to scale software-defined, autonomous systems across air, land and sea. Watching them grow from there into one of Europe's defining defence tech companies has been incredible and this round is a testament to the pace, ambition and execution of the whole team.
