Montreal semiconductor company Stathera has raised US$55 million to scale its silicon timing technology and accelerate the development of products aimed at AI data centres.
The oversubscribed Series B round was led by Maverick Silicon, with participation from Celesta Capital, BDC Capital, MediaTek Innovation Fund, TXC Corporation, and Ultratech Capital Partners. The financing brings Stathera’s total funding to US$75 million.
Stathera is a fabless semiconductor company developing MEMS-based precision timing technology, an alternative to legacy quartz timing components. While timing components are often overlooked, they play a critical role in keeping processors, networking equipment, switches, and optical interconnects synchronized across modern computing systems.
That role is becoming more important as AI data centres scale.
Large GPU clusters depend not only on compute power, but on the ability to move data quickly and coherently across tens of thousands of processors and the networks connecting them. As AI infrastructure grows more complex, issues such as synchronization, jitter, and resilience can become performance bottlenecks.
Stathera says its silicon timing technology is designed to address those challenges as the industry moves toward tighter synchronization requirements, from microseconds toward nanoseconds.
“Timing is the foundation of modern electronics,” said George Xereas, CEO and co-founder of Stathera, in the announcement.
The company plans to use the new funding to move its GEN2 32.768 kHz silicon timing portfolio into mass production, expand its engineering and commercial teams, and launch development of its GEN3 platform for communications, enterprise, and data centre markets.
The GEN3 platform will be based on Stathera’s proprietary DualMode architecture and designed specifically for AI-CED applications. The company is targeting first customer samples in 2028.
Stathera also plans to establish a Silicon Valley office to work more closely with AI, data centre, and hyperscale customers.
According to the company, the communications, enterprise, and data centre segment is the fastest-growing category in the US$11 billion annual timing market. Stathera also cited industry estimates that put the AI data centre time-synchronization opportunity alone at a cumulative US$1.5 billion by 2030.
The company’s GEN2 product line, meanwhile, is aimed at replacing quartz in high-volume electronics. Stathera says its silicon oscillators can be manufactured in standard semiconductor fabs and offer advantages over traditional quartz components, including a footprint up to 85 percent smaller than standard SMD quartz packages, improved resilience, and lower power requirements.
For data centre operators and hyperscale infrastructure builders, the larger story is the growing importance of the supporting semiconductor stack around AI compute.
As AI infrastructure investment accelerates, much of the attention has focused on GPUs, networking, memory, power, and cooling. Stathera’s financing points to another layer of the AI data centre buildout: precision timing hardware that helps keep increasingly dense and distributed compute systems synchronized.
Maverick Silicon principal Josh Miner said modern AI and edge infrastructure are creating new requirements around size, power, stability, and synchronization at scale.
Nicholas Brathwaite, founding managing partner of Celesta Capital, said Stathera’s progress reflects the strength of Canada’s engineering talent and the country’s potential in deep tech.
Headquartered in Montreal, Stathera is backed by deep-technology and strategic semiconductor investors and is positioning itself as an independent alternative in a timing market it says has consolidated around a dominant incumbent.
For Canada’s semiconductor ecosystem, the raise also marks another signal that AI infrastructure demand is creating opportunities beyond chips built directly for compute. As data centres become larger, denser, and more tightly connected, the components that keep those systems running in sync are becoming part of the critical infrastructure conversation.
