DEEPLY Raises $1.65M for Industrial Acoustic AI Expansion

South Korean startup DEEPLY has successfully closed a $1.65 million (KRW 2.5 billion) funding round, signaling a significant step towards international expansion for its innovative industrial acoustic artificial intelligence solution, Listen AI. The investment was spearheaded by Devsisters Ventures, with crucial participation from Soo Investment Capital and Nautilus Investment. This capital infusion is earmarked to propel Listen AI into new global markets, leveraging its unique capability to discern subtle sonic anomalies often missed by human operators.

Listen AI distinguishes itself by transforming underutilized sound data into actionable intelligence for critical industrial processes. The technology is adept at enhancing quality control for mechanical components, analyzing fastening sounds for precision, and enabling predictive maintenance on manufacturing floors. In operational settings, Listen AI has achieved an impressive inspection accuracy rate exceeding 99.87%, underscoring its reliability in demanding environments. The growing adoption of physical AI across robotics and mobility sectors further validates the market's readiness for such advanced sensory solutions.

The efficacy of Listen AI is already being demonstrated in real-world applications. An affiliate of a major automaker, the H Group, is utilizing the system in its domestic and Mexico-based manufacturing plants. Additionally, H Company, Korea's leading automotive motor manufacturer, has integrated Listen AI into its motor production lines. The system's sophisticated algorithms effectively filter out extraneous noise, including human speech, to isolate and analyze target sounds, ensuring they conform to established parameters.

DEEPLY's strategic advantage lies in Listen AI's minimal language and location dependencies, positioning it ideally for rapid global deployment. The company has experienced substantial growth, reporting more than a threefold increase in annual revenue for each of the past three years since the solution's inception. Current expansion efforts are focused on North America, with specific targets including bearing manufacturers and automotive assembly operations. DEEPLY plans to accelerate its U.S. market entry by exhibiting at the upcoming Automate 2026 event in Chicago.

The investment underscores a broader trend of increasing interest in AI applications that enhance operational efficiency and safety in physical industries. The market for industrial AI, particularly in areas like predictive maintenance and quality assurance, is projected for significant growth. Companies like DEEPLY are tapping into this demand by offering specialized solutions that address specific pain points, moving beyond generic AI platforms. The funding also aligns with DEEPLY's pursuit of the TIPS program, a government initiative supporting high-tech startups.

Seungwoo Lee of Devsisters Ventures highlighted the transformative potential of DEEPLY's technology, stating, "DEEPLY is playing a critical role in transforming sound—a data source that has historically been underutilized—into a core industrial data asset." He anticipates the company will forge a new market category by establishing acoustic data as a standardized industrial resource. CEO Suji Lee of DEEPLY added, "Through ongoing requests from clients, I’ve seen firsthand how Listen AI can be applied across a far wider range of industrial settings. With this new investment, we’ll work to demonstrate the value of Listen AI on an even broader scale."
