Croatia's Biggest Conference
connecting Lean, Green, Digital, Finance and Leadership. But size is only part of the story. What really sets chalLEANge apart is how many people are still in their seats when the final panel begins.
Nothing to Hide
No corporate script. No carefully rehearsed answers. Just people who have been there, done it and are willing to tell the story as it really happened. Including the parts that didn’t go according to plan.
More Than a Break
Some of the best conversations happen when the microphones are off. Grab a coffee, meet someone you didn’t expect to meet and see where the conversation takes you.
Our
partners
2025.
A good conference needs more than great speakers. Our partners bring their brands, ideas and energy into the mix, helping make chalLEANge happen both on and off the stage.
LEAN&GREEN
What if efficiency was not about squeezing more out of people, but about fixing the things that make good people waste their time?
AI, automation and new tools are changing how we work every day. We are less interested in what is shiny and new and more interested in what actually makes a difference.
DIGITAL
MONEY
Behind every number is a decision.
Some turn out to be brilliant. Some become very expensive lessons.
We are talking about all of them.
LEADERSHIP
The Office, except nobody gets to call HR.
Forget the inspirational quotes. This is what leadership looks like when people, pressure and difficult decisions enter the room.
1 on 1
stage
The host and someone who changed the game in the industry. Expect a direct conversation, unexpected answers and the kind of details that usually come out once the official programme is over and someone says, “Okay, but what really happened?”
