Congressio
What it is
Congressio brings conference submissions, peer review, decisions, scheduling, and attendee registration into one platform. Its drag-and-drop form builder supports conditional logic, file uploads, and co-author invitations without code. Organizers can auto-assign reviewers, set deadlines, detect conflicts of interest, and enable double-blind review. A public program can include attendee agendas and export to iCal or PDF. Stripe ticket sales support tiers, discount codes, add-ons, VAT invoices, and refunds. QR passes can be stored in Apple and Google Wallet and scanned at check-in; access zones can be limited by ticket tier or capacity. For virtual events, Congressio supports live and on-demand streaming, recordings, e-posters, Q&A, and polls. The free plan permits one active event, 100 submissions, and three team seats. Standard costs $49 a month and allows up to five active events, 1,000 submissions, and 15 team seats. Online ticket payments support EUR, GBP, and USD only. The interface is available in English, German, Spanish, French, Italian, and Portuguese.
