SpaceX Vets Raise $50M for Data Center Optics Startup
Mesh Optical Technologies, a startup founded by three SpaceX alumni, has raised a $50 million Series A. The company aims to apply expertise gained from developing Starlink's satellite laser communications to build high-speed optical links for terrestrial data centers, addressing infrastructure needs for large-scale AI and cloud robotics.
- The Series A funding was led by Thrive Capital, with participation from investors including Also Capital and Banner VC. - AI workloads create massive amounts of "east-west" traffic, where data moves laterally between GPUs within a cluster, unlike traditional "north-south" traffic that flows in and out of a data center. This shift in traffic patterns is a primary cause of networking bottlenecks that optical links can solve. - The founding team—CEO Travis Brashears, President Cameron Ramos, and VP of Product Serena Grown-Haeberli—all worked on developing the optical inter-satellite laser links for SpaceX's Starlink constellation. - Mesh's first product, the Alpha C1, is a 1.6 Terabits per second (Tbps) optical transceiver. The company claims its design improves energy efficiency by 3-5% compared to competitors by removing a power-hungry component, a significant saving at the scale of large AI clusters. - The company is establishing its manufacturing in the United States to provide a non-Asian supply chain for critical optical components, as the market is currently dominated by Chinese suppliers. - Mesh aims to scale production to 1,000 units per day within 2026, positioning itself to accept bulk orders for data center build-outs in 2027 and 2028. - An AI cluster with a million GPUs may require four to five million optical transceivers, illustrating the massive hardware demand Mesh is targeting as compute clusters continue to scale.
