HYBE Winds Down Supertone After AI Voice Investment
HYBE is winding down its AI voice-synthesis subsidiary Supertone after shareholders approved dissolution and liquidation on July 15, according to a July 23 filing reported by Music Business Worldwide. HYBE invested nearly KRW 49 billion, about $35 million, across two Supertone transactions. Investment banking sources cited by Korean outlets said HYBE is negotiating the transfer of Supertone's Shift, Clear, and Air audio tools to an outside buyer.
HYBE is winding down Supertone, the AI voice-synthesis subsidiary it took control of in 2023, after shareholders approved the company's dissolution at an extraordinary meeting on July 15. A July 23 filing, reported by Music Business Worldwide, records the decision and appointment of a liquidator to manage the process.
Music Business Worldwide reports that HYBE told The Korea Economic Daily the decision was part of a realignment of its AI business strategy. HYBE was quoted as stating that it had reviewed options for maintaining Supertone as a corporate entity but concluded that continued operation would be difficult.
Tools may be transferred
Investment banking sources cited by The Korea Economic Daily and Alpha Biz said HYBE is negotiating with an external buyer to transfer three Supertone products: Shift, a voice-conversion platform; Clear, a noise-reduction tool; and Air, an audio-enhancement tool. The reporting describes negotiations, not a completed sale.
Supertone has posted a dissolution notice on its website and lists Hoon Heo as CEO, replacing co-founder Lee Kyo-gu, according to Music Business Worldwide.
Investment and financial results
Music Business Worldwide reports that HYBE first invested KRW 4 billion in Supertone in 2021 for an 18.2% stake, then acquired majority control through a KRW 45 billion transaction completed in 2023. The combined investment was nearly KRW 49 billion, or about $35 million at the respective transaction dates.
The Korea Economic Daily, as cited by Music Business Worldwide, reported Supertone generated KRW 2.3 billion, about $1.6 million, in revenue last year while recording a KRW 15.4 billion operating loss, about $10.5 million. The same report put revenue from transactions between Supertone and HYBE at KRW 61 million last year, down from KRW 200 million in 2023.
Supertone's technology appeared in HYBE-linked releases including the multilingual 2023 single "Masquerade" by MIDNATT and the virtual group SYNDI8, Music Business Worldwide reported. Alpha Biz characterized the liquidation as part of wider scrutiny of HYBE's acquisition record.
For AI-audio practitioners, the reported effort to transfer Shift, Clear, and Air illustrates a recurring pattern in commercial AI: model and signal-processing assets can retain value independently of the corporate entity that developed them. Any buyer would inherit products in technically active areas, including voice conversion, denoising, and audio enhancement, while the reporting leaves their future ownership and distribution unresolved.
Key Points
- 1Supertone entered liquidation after shareholders resolved to dissolve the company.
- 2Reported negotiations cover Shift, Clear, and Air, but no completed buyer transaction or product-continuity commitment has been announced.
- 3Comparable AI restructurings can separate reusable audio technology assets from the company that originally commercialized them.
Scoring Rationale
The closure affects a well-funded AI voice company and may result in the transfer of commercially relevant voice-conversion and audio-cleanup tools. It is primarily a business and ownership event rather than a new technical release, limiting its immediate impact on the broader ML ecosystem.
