Fabless semiconductor company Peraso, which is developing wireless networking chips based on WiGig, has raised $42M Series D, bringing total raised to $79.3M

Context & Ripple Effects
Peraso's $42M Series D lands in a funding cycle where fabless networking-silicon startups are pulling in progressively larger late-stage checks: Astera Labs' $150M Series D and Lightmatter's $400M Series D both dwarf Peraso's round, which makes this a comparatively lean bet on 60GHz WiGig rather than data-center interconnect. The company's $79.3M total also marks it as a patient-build candidate in a market where rivals have scaled faster.
The geography matters as much as the amount: CBRE research puts Toronto among North America's top three tech hubs with the fastest-growing tech workforce on the continent, and Peraso is one of its flagship silicon companies. That profile already produced a landmark exit when Semtech moved to acquire Sierra Wireless in an all-cash deal valuing the Canadian company at $1.2B including debt.
First-order effects
- Peraso gains extended runway to push its WiGig chip designs toward volume production, while its investors take a concentrated position in millimeter-wave wireless at a fraction of the capital deployed into interconnect peers like Astera Labs.
Second-order effects
- The Semtech–Sierra Wireless deal sets the template for how Canadian wireless-semiconductor assets get valued, making Peraso a plausible target for connectivity-focused acquirers if WiGig adoption materializes.
Third-order effects
- If the pattern holds, specialized fabless networking chipmakers follow a fund-then-acquire path rather than independent scale-up, with strategic buyers consolidating niche wireless IP — and Toronto's rise as a top-three North American tech hub gives it an outsized share of that pipeline.
The trend: Fabless networking-silicon startups are riding rising late-stage capital intensity, with strategic acquisitions emerging as the dominant exit path and Toronto becoming a serious secondary center of that activity.
