Critical Conversation Lab

One conversation can change the course of a working relationship, or a personal one. Break the cycle of recurring, heated conversations that fail to produce agreement. Every unresolved dialogue takes up energy, time and money.

This is what that one unresolved conversation is costing you.

Too much is on the line to walk in unprepared. You know that one wrong move, one defensive reaction, traps you right back in the old dynamic and could fracture the relationship. What you risk by saying it wrong, or saying nothing at all, is already costing you:

Eroded trust

Unspoken issues quietly damage your most important relationships.

Slower decisions

Unresolved tensions stand in the way of progress.

Drained energy

The conversation you avoid keeps taking up space in your mind.

Your own blind spots

Labels, judgments, and the stories you tell yourself can prevent you from seeing the other person clearly.

Walk In Prepared. Walk Out With an Agreement.

A targeted four-week intervention designed to map, test, and break the specific behavioral dynamics that stall critical relationships.

Built on 25+ years of behavioural expertise

Tested on 25,000 individuals across 150 organisations. The barrier to an agreement is never the agenda on the table; it is the behavioral reflex. Our methodology isolates that split-second when your jaw tightens, you stop listening, and you start defending, and gives you the exact mechanism to override it.

The simulator

Discover the reflexes, assumptions, and patterns shaping the way you communicate in our diagnostic tool. Designed to identify and replicate your specific behavioral "allergy." You practice against the exact triggers that derail you, taking the hits and adjusting your words safely behind a screen, instead of burning trust at the actual table.

The masterclasses

In four weeks, we break down the exact mechanics of why your conversations derail. You learn to identify your internal narrative and rewire your reflex. Knowledge that will benefit all challenging future interactions.

Practise until you get it right

Do not use your actual relationships as a testing ground. Run the scenario repeatedly in our simulator and adjust your approach before you step into the real conversation.

Built on 25+ years of behavioural expertise

The Critical Conversation Simulator is grounded in Johannes Leerink's work in behavioural transformation, ego dynamics, and leadership. It adapts to your specific situation, reveals your blind spots, and gives you direct feedback on the emotional impact of your responses.

Meet Johannes Leerink

“I do not teach communication tricks, and I do not deal in management theories. Theories fail when the pressure rises. My work is based on a simple, empirical reality: the unspoken dynamic between people decides every conversation. The Critical Conversation Lab is where that method becomes yours.”

Testimonials

"The programme helped me see how I was contributing to the very dynamic I wanted to change. I never expected an AI conversation partner to help me look at myself with such clarity. Step by step, I identified my triggers and practised responding differently, an insight that changed everything."
Karen de Lathouder
COO at Chane
"I saw very concretely what triggered me. That was confronting and useful at the same time. Some things that irritate me about the other person also show up in my own behaviour. I hadn't seen that so clearly before."
Ferdinand Veenman
Interim CEO at VENN Hypotheken

Stop repeating the pattern. Secure the agreement.

Go into that critical conversation with a better understanding of yourself, your patterns, and how you respond under pressure.
