On May 29, 2025 ACE Inventor raised KRW 800 million from the Korea Technology Finance Corporation. The direct investment, based on a technology assessment, followed the company's designation as a Value-Up core company in 2024.

Together with investment from CNT Tech in April and Mobidic Ventures in October, it formed the company's Pre-A round. The funds were applied to stabilising production equipment and to obtaining KS certification.

The investment followed a technology assessment and an intellectual property valuation. ACE Inventor completed KIBO's IP valuation of its hydrogel solar cell manufacturing technology — a third-party assessment of the commercial value of the technology.
