## About

Based in Osan, South Korea, STACC is a manufacturer and distributor of multilayer piezoelectric ceramic actuators that transform electrical energy into precise mechanical motions. As of 2026, the company is led by CEO Jae-hyung Choi. In September 2026, STACC raised KRW 4 billion in Series A funding from Company K Partners, Shinhan Capital, and Mirae Asset Venture Investment.

The company's core product is a multilayer piezoelectric actuator, that leverages advanced stacking technology capable of integrating up to 100 layers of piezoelectric elements. Piezoelectric ceramic actuators, which may move, vibrate, or generate pressure when an electric voltage is applied, are used in systems and devices that need to move very precisely and minutely, such as medical and industrial machinery. This actuator allows precision control applications across various industries including semiconductors, robotics, and renewable energy sectors. 

The company plans to use the September 2026 funding to accelerate expansion in semiconductor equipment, robotics, and aerospace markets.
