AMW Analysis
Deeply develops Listen AI, an acoustic inspection platform that detects defects, anomalies, and safety events through sound analysis, targeting manufacturing, industrial safety, and security environments. The company, based in Seoul and founded in 2017, had previously raised $266K in seed funding from New Flight. Recent news shows a significant funding increase: Deeply raised approximately $1.8M (2.5 billion won) in a round led by Devsisters Ventures, with participation from Sooin Investment Capital and Nautilus Investment. This capital is intended to support global expansion of its industrial acoustic AI solution. Additionally, Deeply had two papers accepted at IEEE ICASSP 2026, marking its third consecutive year of recognition at that conference. One paper proposes a method for selecting acoustic features relevant to manufacturing and public safety applications. The combination of new funding and sustained academic validation suggests the company is deepening its technical foundation while scaling commercially.
