Aki Shiota
Founder & Principal Consultant
I established Castlebay to bridge the critical gap between technical engineering and business investment in the semiconductor sector. With over three decades of experience at the forefront of the silicon wafer industry, I bring a unique dual perspective: deep technical mastery of materials and processes, and a strategic understanding of global business operations.
My career has been defined by solving "unsolvable" problems—whether it's optimizing atomic-level crystal growth or streamlining multi-national supply chains. Now, I apply that same rigor to help investors mitigate risk and engineers achieve breakthrough efficiency.
