European defense technology startup Helsing on Tuesday said that it’s raised 600 million euros ($693.6 million) in a bumper new round of funding.

The investment was led by Prima Materia, the venture capital firm founded by Spotify

CEO Daniel Ek and by Shakil Khan, an early investor in the popular music streaming app. Ek is also chairman of Helsing.

Existing investors Lightspeed Venture Partners, Accel, Plural, General Catalyst and Saab also put money in, alongside new investors BDT & MSD Partners.

Defense and the technology behind it have become a hot area for investors lately, amid major global conflicts, including the Ukraine war to Israel-Gaza. Last week saw a further escalation of war in the Middle East as Israel launched a series of airstrikes against Iran.
