Edge AI chip firm GrAI Matter Labs was reportedly acquired quietly in fall 2023 by Snap, Inc., the mum or dad firm of social media web site Snapchat, in keeping with a French media report. Whereas there are dozens of edge AI chip startups immediately, this acquisition would signify a uncommon exit for a startup on this sector thus far.
A report within the French media on the acquisition was shared on social media this previous October by certainly one of GrAI Matter’s cofounders, however later deleted. The identical cofounder later shared a submit congratulating GrAI Matter’s crew on the corporate’s acquisition.
GrAI Matter CEO Ingolf Held has since modified his LinkedIn job title to director of {hardware} engineering at Snap, Inc, and altered his profile image to himself carrying Snap’s New Spectacles, an AR glasses product from Snap that isn’t at present on sale to the general public. He’s nonetheless listed as a crew member on GrAI Matter’s web site.
Neither GrAI Matter, Snap, Inc. or Ingolf Held instantly responded to remark requests from EE Instances.

Stateful neurons
GrAI Matter was based in 2016 with a $1 million grant from DARPA to commercialize analysis from the Imaginative and prescient Institute in Paris, France. The Silicon Valley startup has an workplace in Paris, which focuses on machine studying and purposes, and a silicon design web site in Eindhoven, The Netherlands. The corporate raised near $30 million in funding to develop its know-how into an SoC—GrAI VIP—and it at present lists 36 workers on its web site.

GrAI VIP makes use of the corporate’s third-gen AI acceleration microarchitecture, which is digital however vaguely brain-inspired, utilizing sparsity ideas that search for commonality in successive video frames to keep away from processing the identical information a number of occasions. Stateful neurons are used to protect a reminiscence of what has occurred previously. That is mixed with a near-memory compute/dataflow structure for low–latency, low–energy (tens to lots of of milliwatts), actual–time picture and audio processing. The chip is meant for processing or augmentation of video and audio information (the place the output is modified video or audio information, versus metadata).
GrAI VIP can deal with MobileNetv1–SSD operating at 30fps for 184 mW, round 20× the inferences per second per Watt in comparison with a comparable GPU, the corporate beforehand informed EE Instances. GrAI added that additional optimizations in sparsity and voltage scaling may enhance this additional.
The corporate additionally has a mannequin zoo with fashions for picture processing, however lately additionally demonstrated compelling audio use instances, corresponding to separating vocals from music for remastering or karaoke machines.
New Spectacles
What’s in it for Snap? The social media firm can be a {hardware} producer, making two forms of AR glasses underneath the model title Spectacles. Presently, it affords two forms of camera-enabled sun shades.

Third-gen Spectacles, introduced virtually 5 years in the past, are sun shades with cameras within the body that may seize pictures and video then add onto Snapchat. These glasses function two HD cameras, to allow them to create attention-grabbing 3D visible results by combining footage from the 2 cameras. They’ll additionally “remodel [footage] with 3D results,” in keeping with the corporate. Additionally they function a 4-microphone array.
Competitor Meta launched the most recent technology of its related sensible glasses product in collaboration with Ray-Ban in September 2023.
A fourth-gen Snap glasses product, referred to as New Spectacles, has completely different functionalities. New Spectacles has 3D waveguide shows within the lenses, which overlay AR content material over the person’s view, and have hand, marker and floor monitoring. These glasses are primarily based on the Qualcomm Snapdragon XR1 platform, whose Spectra ISP consists of some AI acceleration for picture processing. New Spectacles aren’t at present out there on the market to the general public.
Know-how like GrAI Matter’s low-power AI accelerator may very well be helpful for video or audio manipulation in a possible next-generation Spectacles product. Picture processing, AR visible results, picture filters and audio results would all be inside its capabilities.
An investor slide deck proven at Snap’s fourth quarter earnings name final month reveals “M&A to speed up product roadmap” is certainly one of three capital allocation priorities. This consists of “investing in know-how and groups to enhance our product roadmap.”
In 2021 and 2022, Snap acquired three {hardware}/electronics firms. They have been WaveOptics, a British producer of waveguide shows for AR glasses; NextMind, a French startup creating non-invasive brain-computer interfaces; and CP Show (also called Compound Photonics), a U.S. maker of liquid crystal on silicon (LCoS) and MicroLED shows.
These marked the corporate’s first acquisitions within the {hardware} house, and the primary silicon acquisition through CP Show. Whereas CP Show developed its personal show backplane know-how in CMOS, which was fabbed at GlobalFoundries, GrAI Matter could be Snap’s first processor design acquisition.
Might the GrAI Matter crew probably have the idea for a brand new customized silicon design crew at Snap? Competitor Meta has been making its personal customized silicon for AR glasses in earlier years, however lately introduced it’ll sub-contract customized silicon design for future AR glasses to MediaTek. The hyperscaler nonetheless has a customized silicon unit, however lately laid off a tranche of its workers, in keeping with studies. This goes to indicate how troublesome customized AI silicon design is—even with Meta’s sources.
It’s unclear at this level whether or not a post-acquisition GrAI Matter would proceed to serve its current prospects, which embrace module makers, automotive tier-1s, system integrators and distributors. A notice on earlier Snap acquisition WaveOptics’ web site means that the corporate nonetheless helps exterior prospects, which might presumably embrace Snap’s opponents.
