Staera Semiconductor is poised to revolutionize AI data transfer with its innovative Lightwire technology, designed to address the growing energy demands in AI systems. The company has recently emerged from stealth mode, announcing a successful $4.6 million pre-seed funding round led by Openspace Capital, with participation from SGInnovate, Black Kite Capital, 28 Holdings, In Group, and Decimus Technologies.
The crux of Staera’s breakthrough lies in its ability to integrate optical data connections directly inside silicon chips, replacing the traditional copper wiring that struggles to keep pace with modern AI processors. As AI systems require ever-increasing data movement, the limitations of copper connections—a loss of electrical performance over distances—have become a significant bottleneck. Lightwire’s optical solution uses light generated within the chip itself, promising considerable improvements in energy efficiency.
Staera’s technology aims to reduce energy consumption to less than one-tenth of current optical links, with a projected consumption of under 50 watts at a transfer rate of 24 terabytes per second. This efficiency is particularly crucial as the International Energy Agency anticipates a more than doubling of data center electricity demand by 2030. Staera’s approach aligns with the trend among AI hardware companies increasingly considering optical connections to enhance data-transfer efficiency.
Chief Executive Officer Dr. Andrew Kim emphasized that the recent funding will support the transition from research and development to engaging with customers and commercial deployment. The company is strengthening its U.S. team and forging relationships with customers and supply chain partners, with a commercial release of Lightwire slated for 2030.
Staera has already garnered industry recognition, winning the 3rd ECTC Start-up Competition in May 2026 and securing a runner-up position at the 2026 Lam Capital Venture Competition. Openspace Capital Co-Founder Hian Goh highlighted Staera’s integrated optical approach as a promising pathway toward scalable and energy-efficient AI systems.
About Staera Semiconductor
Staera Semiconductor designs the technology that lets modern hardware scale, by carrying data on light instead of electricity. Its LED-based optical interconnect is fabricated inside a single chip, giving AI compute systems the density to move data from millimeters to meters without trading off size, energy or performance. Staera began as a spin-off from the Low Energy Electronic Systems (LEES) interdisciplinary research group at the Singapore-MIT Alliance for Research and Technology (SMART), MIT’s first research centre outside the United States and its largest international research endeavour.
