RebelCon

Unfinished
Business

About

Not a
conference.

An argument.

RebelCon was born from frustration. From the feeling that the industry kept making promises it wasn’t keeping — around diversity, sustainability, developer wellbeing, the real human cost of the systems we build.

Ten years later, the frustration is still valid. So we’re back. One day, one track, Cork. Practitioners and thinkers who aren’t here to celebrate — they’re here to think, argue, and figure out what comes next.

This year’s theme is Unfinished Business. Because it is.

Programme

Three Acts

One argument.

01
Morning

The Promises We Made

A reckoning. What did the industry commit to over the last decade? What actually happened? This act sets the tone: honest, not celebratory.

Keynote + 2 talks + lightning talk

02
Afternoon

The World We Are Building

AI, power, community, social cost. Talks with a point of view. A panel where participants don’t agree. The tension is the content.

2–3 talks + panel / roundtable
03
Close

Now What

From diagnosis to agency. Not what the industry should do — what you can do. Ends with the community as the final speaker.

2 talks + lightning talk + time capsule
