Scintil Photonics secured $58M to scale integrated photonics for AI factories

Grenoble-based Scintil Photonics, a company developing integrated Photonic System-on-Chip (PSoC) solutions for AI infrastructure, has closed a $58 million Series B round. The funding will drive global hiring, accelerate production, and expand its international footprint as it launches the industry’s first single-chip DWDM light engine.

Built on its proprietary SHIP™ (Scintil Heterogeneous Integration Photonics) process, Scintil’s technology integrates lasers, photodiodes, and modulators onto a single chip, replacing dozens of discrete components to deliver higher performance, efficiency, and density for next-generation co-packaged optics (CPO).

Drawing on more than 15 years of research at CEA-Leti, one of Europe’s leading semiconductor institutes, the company has a strong head start in heterogeneous silicon photonics.

The Series B funding supports the commercial ramp of LEAF Light™, the industry’s first PSoC DWDM-native light engine, aligned with next-generation co-packaged optics (CPO). DWDM (Dense Wavelength Division Multiplexing)-native means the single-chip device can output many precisely spaced wavelengths, dramatically increasing bandwidth while lowering energy use. By reducing power per bit, LEAF Light™ also helps cut the carbon footprint of AI data centres.

Matt Crowley, CEO of Scintil Photonics, shared:

This investment marks a pivotal moment for Scintil as we move to full-scale deployment. Our SHIP™ technology enables integrated photonic solutions with the scalability, energy efficiency, and integration density required to power next-generation compute infrastructure. This efficiency not only reduces data centre operating costs but also contributes to lowering the carbon footprint of AI infrastructure.

With LEAF Light™ entering high-volume production, we’re expanding from our base in Grenoble into the international markets, including the US, to support the world’s most advanced AI factories.

Built on Scintil’s SHIP™ platform, LEAF Light™ enables low-power, high-density optical connectivity, delivering 6.4 Tbps/mm edge bandwidth density today, at roughly one-sixth the power consumption of conventional pluggable solutions. It’s designed for scale-up GPU clusters and emerging AI systems, with reference packaging and integration support to accelerate deployment.

The round was led by Yotta Capital Partners and NGP Capital, with strategic participation from NVIDIA and continued backing from global and regional deep tech leaders. Existing investors Supernova Invest, Bpifrance, and Innovacom also joined, alongside prior strategic backers Robert Bosch Venture Capital (RBVC), Applied Ventures, and ITIC-Taiwan, reaffirming their strong confidence in Scintil’s technology platform and market potential.

Vincent Deltrieu, Managing Partner at Yotta Capital Partners, said:

Scintil exemplifies the kind of innovation leaders we look for, combining advanced manufacturing, deep-tech leadership, and meaningful impact on the energy demands of AI infrastructure. Scintil’s integrated photonics platform is essential to scale the next generation of AI factories. We’re excited to support their global growth as they move to high-volume shipments.

Bo Ilsoe, Managing Partner at NGP Capital, added:

Integrated photonics is becoming a foundation of all AI infrastructure, and Scintil is turning that future into reality. Their technology delivers the bandwidth density and energy efficiency AI factories require with global scalability. We’re excited to support Scintil as they scale deployments and become a leading player in building the next wave of compute and data infrastructure.

The funding will allow Scintil to accelerate hiring and strengthen its US presence while continuing to build from its strategic base in Grenoble. Situated at the centre of Europe’s advanced semiconductor ecosystem, the company benefits from close ties to institutions like CEA-Leti and leading global players in the region, giving it access to top talent and a collaborative innovation environment.

Backed by leading investors and trusted by industry pioneers, Scintil is well-positioned to provide the integrated optical technologies required by next-generation AI factories.
