Retym, a U.S.-based chipmaker with Israeli roots, has secured $75 million in Series D funding, bringing its total raised to $180 million.
The round was led by James Kuklinski of Spark Capital, with continued participation from existing investors Navin Chaddha (Mayfield) and Mamoon Hamid (Kleiner Perkins).
Powering the Backbone of AI Workloads
Unlike Nvidia, Retym doesn’t build chips that directly process AI tasks. Instead, it focuses on programmable coherent DSP (digital signal processing) chips, which boost communication speed within and between data centers — a critical function as AI workloads grow in size and complexity.
With data centers under increasing pressure to handle larger volumes of information faster and more efficiently, Retym’s technology is positioned to become a foundational part of AI-era infrastructure.

Taking on the DSP Giants
Co-founded in 2021 by CTO Roni El-Bahar, Retym is taking aim at a market long dominated by legacy players like Marvell Technology, which holds partnerships with major firms such as Nvidia and Juniper Networks.
“We founded Retym to disrupt a DSP market controlled by just a few semiconductor giants,” said El-Bahar in his debut blog post.
Cutting-Edge Manufacturing and Testing
Retym’s first chip is being produced using TSMC’s 5-nanometer process, one of the most advanced fabrication technologies available. The company has confirmed that the chip is currently in testing.
While the company has operated largely in stealth mode until now, this latest raise signals its readiness to scale and compete on a global stage — providing critical infrastructure for the next generation of AI-powered data centers.
