First
Where TRACE starts — consumers buying a connected diffuser and refills.

Personal fragrance
A scent that is yours, versioned until it is right.
Describe a feeling, smell a draft, refine it, keep it. Reorder the exact version later instead of starting over.
Needs first — First-try acceptance and rounds-to-confirm measured in the paid pilot.

Smart homes
A familiar scent when you come home.
Scenes and schedules on a connected diffuser, with refills that arrive before an ingredient runs out.
Needs first — Proof that owners keep using the device after the first weeks.
Next
Business pilots once the device is proven in homes.

Hotels & hospitality
A signature scent per room type or season.
Boutique hotels and homestays could define a scent identity and keep it consistent across rooms and properties.
Needs first — Pilot partners, commercial-duty reliability and refill logistics.

Offices & showrooms
One brand scent, everywhere the brand lives.
A saved scent record could be played on every compatible device across sites.
Needs first — Multi-device consistency and fleet management.

Retail & experience venues
Scent tied to a space or a moment.
Venues could cue a scent to a product launch, an exhibit or a time of day.
Needs first — Fast switching between scents and low residue.
Later
Long-term platform opportunities.

Gaming & XR
Smell the scene you are standing in.
A scent cued to a moment in a game or film. TRACE has a media-sync software prototype; hardware sync is not yet tested.
Needs first — Trigger latency, residue clearing and immersion tests, starting with one fixed scene.

Travel & tourism
A Scent Card with every photo.
Bring back the smell of a place — starting with controlled plant samples, not entire landscapes.
Needs first — Capture of real-world samples and believable reproduction.

Scent messaging
Send a smell, not just a picture of it.
Share a scent record with someone whose compatible diffuser plays the closest version and asks: ‘Is this it?’
Needs first — Remote playback, compatibility checks and perceived-similarity results.
