One of the loudest arguments in AI right now is about what's actually slowing the buildout down. Broadcom's Hock Tan says it's money, not chips. Pat Gelsinger's answer is different — and he's putting it on a startup's board. "AI is not constrained by capital, it's constrained by power," Gelsinger said last year. On Friday, a securities filing showed the startup he backed, Powerlattice, has raised $86 million to prove it.
The Vancouver, Washington-based company builds what it calls a power delivery chiplet: a small component that sits inside the processor package and shortens the path current travels to reach the processor. Conventional setups route power over long paths and waste energy along the way; Powerlattice says shrinking that path can cut energy use by more than half while boosting performance, according to GeekWire, which spotted the SEC filing.
The $86 million is nearly triple the $31 million the company had raised when it emerged from stealth last November with a $25 million Series A led by Playground Global and Celesta Capital. The new filing shows the company is seeking $111 million total, with 18 investors participating so far — no names disclosed, and Powerlattice declined to comment. Gelsinger, a Playground general partner, sits on the board alongside Celesta's Steve Fu. The founders — CEO Peng Zou, Gang Ren and Sujith Dermal — are semiconductor veterans whose backgrounds span Qualcomm, Intel and NUVIA.
The raise landed the same week Powerlattice claimed an industry first: a monolithic integrated voltage regulator chiplet that packs the controller, power transistors and inductors onto a single piece of silicon. In its demo, the chiplet powered a test rig built to mimic the fast-shifting electrical loads of next-generation AI accelerators, and the company says multiple chiplets can be linked to work as one. "Breaking through the AI power wall requires us to rethink how power reaches the processor," Zou said.
Here's why this matters: the power wall is no longer theoretical. Microsoft walked away from Nscale's Loughton data center this month because the grid couldn't power it, and Google is now building a virtual power plant out of thermostats and batteries just to find another gigawatt. Everybody's attacking the supply side of electricity. Powerlattice is attacking the demand side — watts per chip, from inside the package — which, if it works, multiplies every grid fix.
What to watch next: whether the filing's $111 million target closes with named investors, and which GPU or accelerator makers actually design the chiplet into shipping hardware. Engineering samples are already out for GPUs, CPUs and custom accelerators — but the AI industry has a long history of power breakthroughs that looked great in a demo rig.
