REVORN integrates odor sensing, AI formulation and diffusion hardware to digitize smell so it can be recorded, transmitted and replayed like other media. Its platform combines the Obre sensor (detects airborne odor molecules), the Hearom diffuser and fragrances (blends multiple aroma materials in space) and the iinioi® cloud (stores detection data and generates fragrance recipes via machine learning). In 2024 the company’s proprietary sensory-evaluation AI received patent recognition and its efficacy has been validated in multiple use cases. CEO Hiroaki Matsuoka founded the company while at Nagasaki University after noting disaster-response robots lacked a "nose." With fresh capital the team plans to build higher-precision, portable sensors and automatic fragrance reproduction devices and to broaden adoption across food & beverage, cosmetics, healthcare, automotive and general-purpose applications. To date the firm has raised ¥1.35 billion in total funding.
