Company profile

researched Aug 2026

Pex provides content identification technology for music and video, centered on Music Recognition Technology (MRT) that combines audio fingerprinting, melody matching, and voice identification. The technology is designed to recognize music even when it has been altered β€” sped up or slowed down (content modified at 50–200% of original speed), pitch-shifted, partially obscured, or embedded within other content β€” and can identify recordings from as little as a few seconds of audio. Fingerprints are matched in real time against the Vobile Music Registry, which indexes over 120 million recordings, including registered recordings from the Sony, Universal, and Warner catalogs.

The product line includes Search, an automatic content recognition (ACR) service for on-demand music identification used for compliance; Discovery, which tracks audio and video across platforms on a per-file subscription basis; a Market Share Report product that measures individual rightsholder share on platforms or delivers custom data; and the AI Song Detector, a real-time API that classifies tracks as AI-generated or human-created and, at high confidence, names the generating platform (including Suno, Udio, Boomy, and ElevenLabs). Stated applications are fraud prevention, commercial licensing, black box royalty attribution, and AI song detection.

Following Vobile's April 2025 acquisition, the Pex team operates as the Vobile Music Team and Pex music solutions β€” real-time search, AI-generated music detection, and social media music monitoring β€” are offered under the Vobile brand.

Business model

Pex sells identification and tracking technology and data to rights and platform customers, with at least one product, Discovery, priced as a subscription starting at $1 per file per month; other offerings, including Search, the AI Song Detector API, and Market Share Reports, are sold through direct enterprise sales inquiries.

Recurring per-file subscription fees for content tracking (from $1 per file per month), plus paid identification services, API access, and licensing/market share data reports.

Latest developments

Vobile acquired Pex in April 2025; the Pex team became the Vobile Music Team and Pex's music identification products, including real-time search, AI-generated music detection, and social media music monitoring, are now delivered under Vobile.

β–ΈFull profile β€” market position, technology, go-to-market

Market position

Positioned, together with acquirer Vobile, as a provider of content protection, rights management, and Music Recognition Technology, with a music registry spanning major-label catalogs from Sony, Universal, and Warner.

Emphasis on identifying heavily modified content β€” audio altered in speed, pitch, or partially obscured, or embedded in other media β€” from short samples, and on detecting and attributing fully AI-generated songs to the platform that produced them.

Technology

Audio fingerprinting generates a unique digital signature per audio file, matched in real time against a registry of more than 120 million indexed recordings. This is combined with melody matching and voice identification so that modified audio (50–200% of original speed, pitch-shifted, partially obscured, or nested inside other content) can still be matched, and identification is possible from a few seconds of audio. A separate real-time API classifies songs as AI-generated versus human-created and attributes them to specific AI music generators.

Go-to-market

Direct enterprise engagement via "Let's talk" contact requests, organized around use-case segments for platforms, music distributors, music publishers, brands, rightsholders, and AI-generated music, supplemented by self-serve-style per-file pricing for content tracking.

Digital service providers, music distributors, record labels, music publishers, production music libraries, collection societies, online platforms, brands, and other rightsholders that need to identify, track, or manage music rights across digital platforms.
