    When change gets stuck in the system?

    Change itself is not the problem in your organisation. There are plenty of plans, strategies and project teams. Reports are written, dashboards are monitored. And yet, very little actually moves.

    Not because people are unwilling, but because the system has become heavy. Bureaucracy, old decisions and ways of working that once made sense now mainly slow things down.

    There are many discussions, alignments and approvals. But real movement remains limited. And that creates frustration - not about change itself, but about the lack of progress.

    Do you recognise that feeling that change in your organisation isn’t blocked by resistance, but by the system itself?

    The key to getting change moving again.

    The Guerrilla Change Movement is not a classic keynote about change. No new model, no extra framework, and no heavy programme on top of what is already running. The goal is simpler: to get change moving again.

    Not by pushing harder, but by working smarter. With small, unconventional actions that release energy and move around heavy systems.

    The approach is built on three clear principles:

    • Break Yesterwork – Challenge rules and processes from the past that now mainly slow things down.
    • Redirect Energy – Focus your energy on people and ideas that want to move forward, instead of endless discussions.
    • Create Momentum – Start with small, fast actions to create movement first; mindset follows naturally.

    No extra complexity - just a simple way to get people moving again.

  • What will the audience take away?

    • See clearly where yesterwork drains energy in your organisation

    • Have concrete ideas to start small, unconventional actions

    • Know how to redirect energy to the people who want to move forward

    • Understand why momentum matters more than perfection

    • Feel new space to approach change in a simpler, lighter way

    When and for whom is this keynote ideal?

    'Join the Guerrilla Change Movement' is especially suited for situations where change gets stuck in processes or bureaucracy. When several initiatives have already taken place but real movement is still missing. When a strategy or merger is clear, yet the energy to move forward is lacking. Or when HR, change or communication teams feel like they are talking to walls and discussions keep going without concrete action.


    This keynote is less designed as broad inspiration for everyone. It works best with HR directors, change professionals, communication and marketing teams, and leaders responsible for driving change. People who feel that the issue is not a lack of intention, but that the system itself is blocking movement.
