Femtum: The Mid-IR Laser Weapon for AI Chips
How a 33-person Canadian startup is solving the semiconductor bottleneck you've never heard of.
While the world obsesses over GPU compute, the real bottleneck in AI manufacturing isn't processing power—it's precision photonics. Enter Femtum, a Canadian deep-tech startup wielding mid-infrared fiber lasers to cut, trim, and ablate semiconductor wafers with sub-micron accuracy. They're not building the next AI model; they're building the tools that make AI hardware possible.
"Femtum isn't just selling lasers—they're selling the ability to manufacture the unmanufacturable."
The Precision Problem in AI Hardware
As AI chips become more complex with integrated photonics and 3D architectures, traditional laser trimming hits physical limits. Femtum's mid-IR fiber lasers operate in the 2-20 micron range—where silicon becomes transparent. This allows for internal ablation and cutting without surface damage. While competitors fight in the crowded visible spectrum, Femtum owns the mid-IR frontier where next-gen AI semiconductors live.
The Revenue Engine
With $12.6M in revenue and just 33 employees, Femtum achieves an impressive $381K revenue per employee—remarkable for a hardware company at this stage. Their $3.75M funding suggests disciplined capital efficiency. They're not burning cash on R&D; they're shipping turn-key systems that solve immediate manufacturing bottlenecks. This is the profile of a company that knows its customer's pain points intimately.
The company's leadership team reflects this precision focus: Olivier Renauld (Production & Engineering Director) ensures manufacturing reliability, while Carl Paquet (Business Development) navigates the complex semiconductor supply chain. The laser application scientists—Feng Liang and Alexandre Douaud—bring the academic rigor needed for cutting-edge photonics. This isn't a team chasing hype; they're executing on a specific technical wedge.
- Mid-IR specialization creates defensible moat against laser commoditization
- Turn-key systems reduce adoption friction for manufacturing partners
- 33-person team maintains agility while competing with industrial giants
- $12.6M revenue proves product-market fit in a niche with massive TAM
Femtum is the infrastructure play you missed
While investors chase AI applications, this company is building the photonics tools that make advanced semiconductors manufacturable. With $12.6M in revenue and a laser focus on the mid-IR spectrum, Femtum represents a rare combination: deep technical moat, proven product-market fit, and capital efficiency in hardware. For founders, this is a masterclass in vertical focus. For investors, it's a reminder that the biggest opportunities in AI infrastructure aren't always in the software layer.
