Retym, a semiconductor firm, has emerged from stealth mode, having raised over $180 million across multiple rounds to drive AI Infrastructure Innovation.
Led by Spark Capital, the company secured $75 million in Series D funding.
Retym specializes in programmable coherent digital signal processing solutions for cloud and AI infrastructure, a foundational technology that enables more efficient transmission within and between AI data centers.
Joining Spark Capital were existing investors Kleiner Perkins, Mayfield, and Fidelity Investments, all of whom participated in the round, further demonstrating confidence in Retym’s vision and execution. The Series D funding will support scaling to production and further advancements in product development.
Retym enters the market at a time when the boundaries between “inside the data center" and "data center interconnect" are becoming increasingly blurred.
“Coherent optics and the DSPs that drive them are becoming increasingly crucial for AI-driven data centers as data volumes and performance requirements continue to rise,” said Vlad Kozlov, founder and CEO of LightCounting.
A recent Dell’Oro Group forecast predicts that global spending on data center compute and networking will exceed $1 trillion annually within the next decade, making optical networking and DSP solutions a key tool to address AI needs.
A diverse set of players will drive this trend.
The research firm stated that while the top four US-based cloud service providers (SPs)—Amazon, Google, Meta, and Microsoft—will account for nearly half of global data center capital expenditures (capex) in 2025, select Tier 2 cloud SPs are poised to increase capex significantly over the next several years.
