DeepX Co., a South Korean designer of AI chips, has signed the first agreements in a Series D round that values the company at about 3.14 trillion won ($2.2 billion), according to people familiar with the matter — roughly four times its previous valuation.
The round opened with 42 billion won from existing investors BNW Investment Co. and DS Asset Management Co., the people said, with more investors expected to join in a later close. DeepX is based in Pangyo, the technology hub south of Seoul that is home to many of Korea’s software and semiconductor startups.
DeepX designs low-power processors for devices that run AI at the edge — cameras, robots, industrial machines — rather than in data centers. The company has said its chips are designed to run vision models and other workloads on a tight budget of electricity, a pitch that has drawn attention as companies look for ways to run AI outside the cloud.
The valuation jump is one of the biggest in Korea’s chip startup scene this year, and it reflects a broader pattern: investors are paying up for AI silicon wherever they can find it. Nvidia’s dominance of data-center chips has left little room for challengers there, so money has flowed to companies attacking adjacent markets — edge inference, memory, networking and the systems around the chips.
Analysts said the round shows the premium extends beyond the biggest names. DeepX is not a household name even in Korea, but its technology touches a market investors believe is about to grow: devices that need AI without a data center nearby. The company’s chips are aimed at products ranging from security cameras to warehouse robots, and it has said its designs can run models that previously required far more computing power.
Korea’s government has made AI chips a policy priority, offering subsidies and support to domestic designers. The country is home to the memory giants SK Hynix and Samsung, and policymakers want Korean companies to capture more of the value in the AI boom rather than supplying raw memory to foreign chip makers. Domestic startups have raised large rounds, and two of Korea’s best-known AI chip companies merged last year to compete more effectively.
The funding structure is typical for the Korean market: a first tranche signed with existing backers, followed by a larger close that brings in new investors. The 42 billion won commitment from BNW Investment and DS Asset Management anchors the round, and people familiar with the process said the valuation reflects the appetite of overseas funds as well as domestic ones.
The AI chip market is bifurcating. Hyperscalers buy tens of thousands of GPUs for giant training clusters, while a long tail of companies wants smaller, cheaper chips for specific jobs. Edge AI was slow to take off, analysts said, but the arrival of capable small models has revived demand for inference at the device level, where power and cost constraints rule out a full-size GPU.
DeepX’s bet is that this second market becomes large. Its chips compete with designs from Nvidia, which sells lower-power processors for edge devices, and from a field of startups in the United States, China and Israel. The Korean company’s edge, analysts said, is its connection to local manufacturing and its focus on power efficiency for the specific workloads — vision, sensing, control — that dominate edge devices.
High valuations carry risk. DeepX and its rivals must convert design wins into volume production, a step that has tripped up many chip startups, and they depend on foundries for manufacturing at a time when leading-edge capacity is tight. The company has said it works with established foundries, and analysts said its design strategy keeps it on process nodes that are in ample supply.
The round also signals something about the state of the market. Capital is flowing to AI companies of every size, and valuations are climbing even for startups without public revenue figures. Investors appear to be pricing in a future in which AI computing happens everywhere — in phones, cars, cameras and factories — not just in data centers.
The deal also shows how the AI investment wave has spread beyond the usual centers. Venture money that once concentrated in Silicon Valley now flows to chip startups in Korea, Israel, Europe and Japan, and valuations in those markets have climbed alongside their American peers. Korean semiconductor companies, long seen as conservative, have been drawn into the AI frenzy by the success of SK Hynix, whose high-bandwidth memory became an essential part of Nvidia’s AI systems and turned the country into a critical node of the AI supply chain.
DeepX’s founders have said the company’s goal is to make AI chips that any device maker can use, the way any phone maker can buy a processor. That ambition puts it in a crowded field, but investors are betting that the market is big enough for several winners. The fourfold jump in valuation is the market’s way of saying that DeepX is one of the names that matters.
For DeepX, the fourfold jump is a bet on a simple idea: that the next wave of AI will not run only in giant data centers, but inside the machines where most computing actually happens. The valuation says the market agrees, and the Series D tranches will determine whether the money follows the number.
