Spark, Mayfield, and Kleiner Perkins pour another $75M into AI data center chipmaker Retym

Retym, a U.S. chipmaker with Israeli roots, has raised $75 million in a Series D funding round led by James Kuklinski of Spark Capital, with participation from existing investors Mayfield and Kleiner Perkins. This brings Retym's total funding to $180 million. The company, founded in 2021, is developing a "programmable coherent digital signal processing DSP" chip aimed at improving data center communication both internally and externally. While not a direct competitor to Nvidia GPUs, Retym's technology addresses the increased demand for faster and more efficient data centers due to the rise of AI.

Retym's CTO and co-founder, Roni El-Bahar, aims to introduce competition in the DSP market, which is currently dominated by companies like Marvell Technology. The startup is utilizing TSMC's 5 nanometer fab for its first chip, which is currently in testing. Retym has maintained a low profile until now, with El-Bahar recently publishing a blog post outlining the company's mission to challenge the existing DSP market leaders.
