Lovable User Builds Cannes Lions Event App in 24 Hours to Solve Conference Chaos.

Marketing professional Lana Ivory built a full-featured event management app in under 24 hours using Lovable, turning personal frustration with conference logistics into a functional web application that other attendees can now use during Cannes Lions.

The app, called Cannes Companion, emerged from a common problem at large conferences. Within 24 hours of planning her first trip to Cannes Lions International Festival of Creativity, Ivory had accumulated 12 spreadsheets, 40 RSVP links, 6 overlapping dinner invitations, and events scheduled 25 minutes apart with no clear way to manage the chaos.

The application aggregates Cannes events into a single interface and syncs with Google Calendar to build a unified itinerary. It flags schedule conflicts and impossible travel timing, uses the Mapbox API to display a live interactive map for both public and private events, and includes an opt-in feature that lets users see who else is attending specific events.

Ivory also built in a feedback mechanism. Users can submit corrections to event information or report missing details directly through the app's profile tab, though she notes the project is still a work in progress.

The build demonstrates what's become possible with AI-powered development tools. Ivory described herself as non-technical but was able to turn a specific pain point into a deployable application that aggregates data, handles calendar integrations, renders interactive maps, and manages user profiles.

This type of rapid build aligns with recent improvements to Lovable's capabilities. The platform recently introduced subagents that can research, explore, and work on different parts of a project simultaneously, making complex builds faster.

What's notable is not just the speed but the scope. Cannes Companion handles multiple integrations (Google Calendar, Mapbox), manages user data and permissions, displays dynamic maps, flags logical conflicts in scheduling, and includes a user-facing feedback system. These are features that typically require coordination between frontend developers, backend engineers, and API specialists.

Ivory's LinkedIn post announcing the project highlighted a shift in who can build software: "We live in a time where you don't need to be technical to build something useful anymore. Now tools like Lovable let you turn a pain point or insight into something real people can actually use."

The Cannes Lions festival runs annually in France and attracts tens of thousands of marketing and advertising professionals. Events span beaches, conference centers, brand activations, and private dinners, creating exactly the kind of logistical complexity Ivory's app addresses. Her post noted that despite being "the most important week in marketing," coordination still happens primarily through spreadsheets.

Builds like this suggest a pattern where individuals close to a problem, with domain expertise but no coding background, can now ship solutions directly rather than waiting for engineering resources or trying to explain requirements to developers unfamiliar with the context.
