OVNI Capital invests in Lightspring
Funding Provisional 92% confidence first seen
Lightspring announced it closed a €3.1 million seed round led by Atlantic and OVNI Capital, with other participants including Concept Ventures, Ixcore, Plug and Play Ventures, and industry angels. The funding is reported as part of total financing of over €3.5 million, after an additional €350,000 i-Lab grant, and will support scaling Lightspring’s 3D lithography-based optical interface technology from lab to a production-ready manufacturing line, including development of its PDK and design tools. The investment matters because it targets the photonic integrated circuit packaging bottleneck by aiming to make optical coupling more reproducible and manufacturable at volume.

Deal terms as reported in the coverage below.
Decision brief
- What changed
- Lightspring announced a €3.1 million seed round led by Atlantic and OVNI Capital, with total financing reported at over €3.5 million including a €350,000 i-Lab grant. The company said it will use the funding to move its 3D lithography-based optical interface technology from lab work to a production-ready manufacturing line and to expand its PDK and design tools.
- Why it matters
- For leaders exposed to photonic hardware supply chains or advanced chip manufacturing, this financing supports a company specifically targeting the packaging and optical-coupling bottleneck in photonic integrated circuits. If Lightspring can make optical coupling more reproducible and manufacturable at volume, it could improve manufacturability and scaling options for photonic products; however, that outcome remains contingent on successful transition from lab process to production line.
- Evidence
- The reported facts come from a single Tech.eu article citing Lightspring’s announced seed round, total financing, and stated use of proceeds. The coverage is internally consistent on the funding amounts and the intended focus on moving from lab-stage process development to production-ready manufacturing.
- What remains uncertain
- This is based on one outlet’s coverage of the company’s own announcement, with no independent validation of technical performance, customer adoption, or manufacturing readiness. It is also not yet clear how quickly Lightspring can industrialize its process, whether its PDK and design tools will be adopted, or how material its approach will be relative to other photonic packaging solutions.
- Monitor next
- Watch for Lightspring to disclose concrete production-line milestones, customer or foundry partnerships, or evidence that its PDK and design tools are being adopted in commercial photonic manufacturing workflows.
