Optics11 has secured €50 million in follow-on equity funding to support its international growth. Existing investors FORWARD.one, Value Creation Capital, SET Ventures, and JOIN Capital participated in the round. The Dutch company develops fiber-optic sensing systems for underwater surveillance and electricity grids.
Funding so far
The latest round brings investment in Optics11 to more than €100 million over 15 months. All four participating investors had previously backed the company. Optics11 reports growing international demand from governments, infrastructure operators, and industrial partners.
Company background
Optics11 was founded in 2011 as a spinout from Vrije Universiteit Amsterdam. The company is led by CEO Paul Heiden and operates in defense and energy infrastructure markets. Earlier in 2026, the Dutch Ministry of Defense selected its OptiArray technology for the ASWINABO anti-submarine warfare program.
How the technology works
OptiBarrier uses seabed sensors to detect and classify underwater targets at distances of up to 100 kilometers from shore. OptiArray provides mobile underwater surveillance through a towed sensor system. Its OptiFinder platform monitors high-voltage electrical equipment to detect and locate early signs of faults.
Optics11 plans to use the new capital to increase manufacturing capacity and expand internationally. The company also aims to strengthen its operations to meet growing customer demand. These efforts will support wider deployment of its sensing systems across maritime security and energy infrastructure.
