Mwaliko - Digital Invitations & Event Registration

The problem

Organizing an event in Tanzania; a wedding, a conference, a graduation usually means running guest lists and payments by hand: tracking who's confirmed, who's paid, what they're owed, and manually sending invitations one by one. Different events also work differently. A wedding might collect contributions toward the celebration; a conference sells tickets; a party is just a free RSVP. Forcing all of these through one rigid process is what makes it tedious, and doing it manually is what makes it error-prone.

What we're building

Mwaliko is a mobile app (iOS, Android, and web, built with Expo/React Native and Supabase) that runs the guest lifecycle end-to-end, adapting to the kind of event it is:

• Event types with sensible defaults - organizers pick from wedding, conference, party, graduation, ceremony, or other, and the event's invitation model, guest terminology ("Guests" vs. "Attendees"), and invitation template default sensibly for that type.
• Four invitation models, one system:
  • Contribution tiers - guests give toward the event and automatically earn a single or double invitation card once they cross a threshold.
  • Free self-registration - guests register themselves through a public link and get their invitation immediately.
  • Paid tickets - self-registration collects the guest's details and returns payment instructions; the ticket is released once payment is confirmed.
  • Invite-only - the organizer stays in control of who's added.
• Public self-registration - each event can get a shareable public link where guests register themselves, without needing organizer login or manual entry.
• Automatic mobile money matching - a webhook receives mobile money payment callbacks, matches the paying phone number to a guest (and, when set, to the event's own collection number to avoid cross-event mix-ups), and records the payment automatically - duplicate callbacks are safely ignored.
• Automatic invitation delivery - the moment a guest qualifies (crosses a contribution threshold, completes free registration, or pays for a ticket), their invitation card or reminder goes out over WhatsApp/SMS via Africa's Talking, with no manual step in between.
