What Sixième Son does

Sixième Son is a Paris-headquartered sonic branding agency founded in 1995, widely cited as the first dedicated sonic branding firm globally. It designs audio identity systems for enterprises, covering sonic logos, brand anthems, UX sound design, vocal identity for voice interfaces, in-store sound design, and original music for advertising. The firm operates 100% in-house and runs six offices across Paris, New York, Toronto, Dubai, Singapore, and Madrid, having produced more than 500 sonic identities for clients in banking, insurance, FMCG, pharma, automotive, consulting, transport, consumer electronics, sports, and media — including AXA, Sanofi, Renault, McKinsey, LUX, Maybelline, SNCF, Samsung, and Michelin.

The firm's technical differentiator is its proprietary Sonic M.A.P.™ research methodology, combined with an exclusive neuromarketing partnership with Datakalab, which applies biometric facial-coding and emotional analytics to measure audience response to sonic assets before deployment. The Vocal Identity service line extends the offering to AI-driven voice assistants and conversational interfaces, positioning the firm for the rising demand for brand voice in machine-to-human interactions. Awards across Transform, Clio, Muse, iF, and similar programs provide external validation.

The business model is B2B professional services: project-based sonic identity creation (strategy, composition, production, sound design) combined with multi-year licensing and retained advisory engagements. Pricing is quote-based and aligned with enterprise marketing budgets, with the in-house model capturing full margin between creative output and client delivery. The firm is privately held and independent, with no disclosed funding rounds, M&A, or external investors.
