Happening 28th October

Metaphorum, THE global online festival celebrating Clean Language and its ever increasing variety of applications will be back and better than ever in 2023! 


Saturday, 28 October, 2023


This global event runs based on a 9am (09:00) to 10pm (22:00) GMT time zone.
Please be sure to check how YOUR timezone relates to GMT.

01:00 – 14:00 PDT | 04:00 – 17:00 EDT | 09:00 – 22:00 GMT | 10:00 – 23:00 CET | 17:00 – 06:00+1 JST

World Time Buddy    and    Time and Date  
are two useful tools for global time organization.

Learn new ways of self-organizing and discover new perspectives on:

  • the work of David Grove
  • Clean Language, Clean Space, and Emergent Knowledge
  • Symbolic Modelling, Systemic Modelling, and other new clean language models
  • applying any or all of these in ‘real-life’

You’ll meet leading figures of the Clean Community such as Penny Tompkins & James Lawley, Judy Rees, Angela Dunbar, Caitlin Walker, Marian Way, and others.

There will be a rich mixture of fellow explorers from around the globe: coaches and trainers, hypnotists and Agilists, teachers, artists, facilitators, managers, performers…

If they love Clean they will be there!

Together we co-create a thrilling event featuring deep dives into personal and professional development, light-touch ways to use Clean in everyday contexts, and all points in-between.

What You Need To Know

Most attendees will have at least some practical experience of using Clean. Beginners are welcome, as long as you are OK with sometimes feeling out of your depth.

This is NOT a taster, nor an event to sell people the idea of Clean.

This IS a global community event to share what you know, what you have learned, what you have created, and what you are excited about in relation to Clean Language and Clean technologies.

This IS a creative event; a place to connect and test and share ideas with others who know or use clean language models and methodologies.

This IS a place to showcase, to get feedback, to crowd-source, to learn, to play, and to have some good clean fun!

The event will run for approximately 13 hours, from about 9 am to 10 pm GMT time

[0100 – 1400 PDT | 0400 – 1700 EDT | 0900 – 2200 GMT | 1000 – 2300 CET | 1700 – 0600+1 JST].


There will be breaks!

And of course, you are not obliged to participate in the whole thing!

The lengthy span is to ensure people from around the world can join for at least part of the event.

Some sessions may be recorded, but this is not guaranteed; please plan to attend live and participate actively for at least part of the day.


We’ll use a variety of tools to connect but Zoom video calling via the QiqoChat online portal will be the main one.

To attend, you will need:

  • a reasonable internet connection
  • a headset
  • a webcam
  • a quiet place to call in from.


The main language of the event is English. We expect that there will be some sessions in other languages as well. Using a balance between scheduled sessions and rooms for open space or emergent sessions you are welcome to propose sessions in other languages too.


It was delightful and resonated beyond dreams…      Claudia Renchy

It was such a great event. I learned a lot during all sessions (either really new understandings or confirmation that I already know many things or surprising myself by noticing that I am able to do things/demonstrate behavior I was formerly not aware of).


What a feast of Clean treats. As ever, it was rich with connection,
learning, and fun. Here’s to the next one, Metaphorum 2021.

Jackie Lawlor

Wow, what an amazing day yesterday. It was great to connect to new old old friends. It inspired me to make a politics video and I am now itching to declutter following the memorabilia session with Andrea Chiou.

Brian Birch

It was fantastic! Thanks to all that contributed by being there,
presenting, extending, preparing, supporting…

Irene Kuhn

A very special Metaphorum Magic! Co-created at such an important time for such valuable connection, curiosity, and collaboration! Much appreciated.

Anna Munro Kua
