Why Flux

People first. Tools second.

Most platforms optimise for the organiser. We optimise for the people who show up. When your members are engaged, everything else follows.

Free. Actually free.
No tiers, no feature gates, no “upgrade to unlock”. The entire platform is free for every user, group and every event. Want to collect payments? We charge a flat €0.55 per transaction. No additional percentage cut!
100% European
Built, hosted, and owned in Europe. Your data stays in Europe, full stop. No overseas cloud dependencies, no data transfers.
Engagement is our focus
Every feature exists to strengthen the bond between your group and its members.

Service fee of €0.55 excl. VAT per paid transaction. Payment method fees from the bank are separate (e.g. an iDeal payment totals €0.99 incl. bank fees, incl. Dutch VAT). All payment methods are available upon request.

When our members open an event, they see the photo album of past editions right above the upcoming one. It creates a sentimental sense of community and belonging, which importantly led to more future sign-ups as well.

Groups

Your community, your identity.

Give your community a home that feels like yours. Set your own colours, logo, and description: members see your brand, not ours. They join with their company e-mail, see what’s coming up, and stay in the loop.

  • Custom primary colour, logo, and description for a strong group identity
  • Flexible access control: open, invite-only, or restricted by e-mail (domain).
  • Your events inherit the group’s look and feel automatically
  • Publish events and manage members from one place

Events

From house parties to festivals.

Whether it’s a casual get-together, or a large-scale event with multiple ticket types, upgrade options, and deposits: it just works. Share the link, watch people sign up. No app required.

  • Tickets by general URL: no more “I can’t find my ticket” e-mails
  • Multiple ticket types, upgrades, deposits, promo codes
  • Live attendance and revenue dashboard
  • Payments built in: just €0.55 flat per transaction, no percentage
1200 young professionals at the Intercompany Festival on the beach

Case

Intercompany Festival

1,200 young professionals. 26 of the world’s most renowned corporates. One beach. The Intercompany Festival needed to handle thousands of tickets across dozens of company groups, without drowning in logistics.

  • We like the app, but the attendees could sign up via the website all the same.
  • Managed ticketing for all 26 corporate groups from a single dashboard
  • Tickets by URL. From 232 “where’s my ticket?” support e-mails, to 0 this year.
  • Access gated by corporate e-mail domains: both secure and scalable.

“Hosting an event for 26 of the world’s most renowned companies required strong quality of service. Flux delivered.”
