Index locally
Choose which photos and videos to include. The Constellation app analyses them on your device.
Private media discovery for events and organisations
Find the media
your network already has.
After a conference, offsite, or member event, the best photos are spread across hundreds of phones. Constellation lets attendees find the ones they appear in — without anyone uploading their camera roll to a central library.
Federated search. Selective sharing.
Constellation indexes media locally, stores searchable metadata securely, and lets owners approve exactly what gets released.
Search privately
Users search by example face, group photo, object, or similar image.
Request access
Matching media is surfaced as a request, not an automatic download.
Approve delivery
Owners approve, reject, or ignore requests. Approved media is relayed securely.
Built for events and the organisations that run them.
Wherever an event’s media is spread across attendees and devices, Constellation gives organisers a private, searchable sharing space.
01
Conference & event media exchange
Help attendees find photos of themselves, colleagues, speakers, and groups — from the official photographer and from each other.
02
Agencies & venues
Offer a branded media space as part of every event you host or produce, with each event kept separate and time-limited.
03
Associations & member groups
Give professional bodies, sports clubs, and member organisations an ongoing private space for gatherings, fixtures, and awards.
Privacy is the architecture, not a setting.
Constellation is designed around local processing, permissioned requests, and temporary encrypted delivery.
Privacy-first by design
- Original media stays with the owner unless sharing is approved.
- Search can be performed using an example image instead of named identities.
- Approved files can be encrypted before temporary relay.
- Collaboration spaces define who can search, request, and share.
- Audit history keeps requests and approvals accountable.
- Participants opt in to each space, and organisers control who can join.
Pricing built around events and organisations
Start free, then choose the point of the star that fits your organisation.
Organisers pay; attendees and members join free. Plans are priced per event or per organisation — never per participant — and sized by the media your participants approve and exchange.
