TLDR: MIT spinout Vertical Semiconductor has successfully raised $11 million in seed funding, led by Playground Global. This investment will fuel the development of its innovative vertical gallium nitride (GaN) chip technology, designed to revolutionize power delivery and energy efficiency for the rapidly growing artificial intelligence sector. The technology promises to reduce heat, shrink the power system footprint by 50%, and improve efficiency by up to 30% in AI data centers.
Cambridge, MA – October 15, 2025 – Vertical Semiconductor, an MIT spinout, today announced it has secured $11 million in a seed funding round. The investment, led by Playground Global, is set to accelerate the development of the company’s pioneering AI power chip technology, which aims to tackle critical challenges in power delivery and energy efficiency within the burgeoning artificial intelligence industry.
The rapidly expanding AI sector is currently grappling with unprecedented power consumption and thermal management issues, particularly within data centers. Vertical Semiconductor’s innovative approach centers on vertical gallium nitride (GaN) transistors, a significant departure from conventional horizontal semiconductor designs. This technology reorients current flow to travel perpendicularly through the bulk of the GaN wafer, rather than laterally along the surface of the chip. This fundamental shift is expected to yield substantial benefits.
According to the company, their vertical GaN chips offer a compelling solution by improving power efficiency by up to 30% and enabling a 50% smaller power footprint in AI data center racks. This breakthrough is poised to dramatically reduce heat generation, shrink the physical size of power systems, and significantly lower energy costs associated with intensive AI infrastructure. The company emphasizes that this advancement is crucial for unlocking the next generation of AI compute capabilities, fostering more powerful and sustainable AI systems by addressing the core bottleneck of efficient power delivery to AI silicon.
