Retym, a U.S.-based chipmaker with Israeli origins, has successfully raised $75 million in a Series D funding round led by Spark Capital. Existing investors, including Mayfield and Kleiner Perkins, contributed to the total funding of $180 million. The startup is developing a novel programmable coherent digital signal processing (DSP) chip aimed at enhancing communication within data centers. Founded in 2021, Retym aims to introduce competition in the DSP market, primarily dominated by major semiconductor companies. Its first chip is currently in testing at TSMC's 5 nanometer facility.
