For cultural teams
Move from programmes and events to a shared archive.
Gather, review, and publish in one space without stitching together several tools.
A shared visual archive
Images that
stay together.
Gather photographs and artworks from the people around you, shape them with your team, and create a gallery that grows with your practice or community.

Shared work
01 · The scattered archive
Images are made together.
Archives often are not.
Work gets scattered across phones, chats, folders, and accounts that teams eventually lose access to. Sidera gives the gathering and the outcome one shared place.
- Contributions arrive through too many channels.
- Published selections lose context and attribution.
- Earlier projects become difficult to find and use again.
What Sidera is
One place for gathering, shaping, and showing the work.
Sidera is a shared visual archive. It keeps contributions, collections, context, and the final gallery connected instead of splitting the work across a shared drive and a separate website.
02 · One continuous practice
From contribution
to living archive.
Four clear steps keep work connected to the people, context, and collections around it.
- 01
Gather
Share a link or QR code. Contributions arrive in one place without requiring every contributor to create an account.
- 02
Shape
Review the work, add context, and organise it into collections — exhibitions, projects, series, or periods of time.
- 03
Share
Create a considered gallery for audiences, partners, curators, or your community.
- 04
Keep
New collections remain connected to earlier ones. The result is a growing visual archive, not another forgotten folder.
03 · Made for cultural work
A shared memory for teams.
A living archive for artists.
For artists
Keep a living archive organised around your practice.
Bring works, projects, periods, and exhibitions together — not organised around a storage system.
04 · A considered outcome
The outcome is not a folder. It is a gallery.
Works remain connected to their collection, context, and attribution. Visitors see a considered presentation while the full work remains accessible beyond a promotional crop.
Manage a personal archive and an organisation’s gallery with the same login. Each Sidera space has its own content, team, limits, and subscription.
05 · Clear boundaries
Content, access, and billing stay distinct.
- Access comes from membership in a specific Sidera space.
- Paying for a space does not automatically provide access to its content.
- Every space has its own subscription and limits.
- Cancelling a subscription does not delete the space.
Pilot pricing
Begin with one space.
Start with a 14-day trial and no payment card. Pilot paid plans begin at €12 per month, excluding VAT, for one Sidera space.

Create a place for work that should not remain scattered.
