- by nlqip
From Celestial AI to Untether AI, these startups are seeking to challenge Nvidia’s AI computing dominance or deliver complementary chip technologies that could shake up the tech industry.
While Nvidia commands tens of billions of dollars in AI chip spending every quarter, there are a good deal of companies and investors who believe there is room for other winners in the AI infrastructure market, whether it’s for chips at the edge or in data centers.
Nvidia may face larger threats in the forms of AMD and, to a lesser extent, Intel, as well as its largest cloud partners—Amazon Web Services, Microsoft Azure and Google Cloud—who are building their own AI chips among other homegrown silicon efforts.

But the AI computing giant is also up against a small army of entrepreneurs and investors who are propping up new chip solutions with novel design techniques and big claims about how they could enable faster and more efficient AI computation.
The semiconductor startups behind these efforts include those focusing on the edge market such as Hailo, SiMa.ai and Untether AI as well as those building chips for AI data centers like d-Matrix, Groq Tenstorrent.
It’s not all about competition, however. Some semiconductor startups, like Enfabrica and Lightmatter, are working on complementary chip technologies that could, for example, speed up the transmission of data between AI servers.
What follows are CRN’s 10 hottest semiconductor startups of 2024, which, in addition to the aforementioned startups, also include Celestial AI and Etched.
