Team development, shaken up!

We make teams laugh, clash, build and try again.
No standard team building or coaching, but a playful mirror and a creative kick in the butt.

🎭 Playful and sharp.
🛠️ Practical, stimulating and with an edge.
🥄 You bring your team — we'll stir the pot.

When was the last time your team actually played?

Laugh or learn? Both.

Some teams are mainly interested in having fun together and bonding. Others want to tackle a real challenge. Most teams actually want both – even though that’s never stated as such in the application.

That’s where our sweet spot lies. We structure every experience in the same way: first play, then reflection. Fun as the starting point, change as the result.

We take playing very seriously!

Targeted workshops & team coaching

For teams with a genuine challenge. Trust, communication, change, stress. We don’t skirt around the problem; we tackle it head-on. In Brussels or at your venue.

70% targeted, 30% corner off

Surprising team building in Brussels

For teams who want to laugh, build and bond at venues across Brussels that have a story to tell. You don’t know what to expect. That’s precisely the point.

70%: fun; 30%: deeper than you’d expect

Organise a team event in Brussels

Looking for a unique experience for your team? We’ll organise the programme, venue and catering – always with a twist. All you have to do is turn up.

70% – no worries, 30% – a surprise, 100% – a mussel man

Our participants are happily playing along.

Wij deden een workshop van Mossels from Brossels rond verbindende communicatie en waren hier erg tevreden over. De workshop werd op maat gemaakt aan de hand van uitgebreide briefings zowel vooraf als nadien. Bovendien was de activiteit zelf origineel en leuk, maar haalde ze ook een aantal pertinente zaken naar boven waar we verder mee aan de slag kunnen. De begeleiding was professioneel en enthousiast, met veel aandacht voor de groepsdynamiek. Een absolute aanrader voor organisaties die op zoek zijn naar een kwalitatieve en leuke teambuildingervaring!

Our team had a great experience working with Gert-Jan from Mossels from Brossels. He is an excellent listener and observer who knows how to choose the right games and activities to encourage collaboration, bring out different perspectives, and identify areas where action is needed. We really appreciated his thoughtful and engaging approach!

Dans le cadre de mes fonctions chez AXA Belgium, j'ai fait appel à Mossels from Brossels pour un événement que j'ai mis sur pied pour un public de managers ... Super expérience, bonne compréhension des enjeux et des besoins. Je ne voulais pas d'un événement "clé sur porte" et nous avons donc fortement collaboré sur le concept. Très chouettes moments de co-création. Très bonne flexibité et prix très correct. L'essayer c'est l'adopter ! Merci Gert-Jan !

We hadden een zeer fijne lachyoga-sessie dankzij het team van Mossels from Brossels. Het was een fijne mix van improvisatie en lachoefeningen. De instructrice hield goed rekening met de groepsdynamiek en zorgde voor een goede afwisseling. Zeker een aanrader!

We had a great team-building day organized by Mossels from Brussels! Gert-Jan was extremely flexible and attentive, taking the time to understand our team's needs and context to create an experience that really suited us. Despite the warm weather, the schedule was adapted and ran smoothly. The activities were interactive, engaging, and brought everyone together in a fun and relaxed atmosphere. A big thank you to Gert-Jan for his professionalism, flexibility, and positive energy throughout the day.
Playing is the norm – mussels from Brossels

We believe in a world where play is the norm!

Why ‘Mossels from Brossels’? Honestly? Because the name piques your curiosity. And curiosity is exactly where every amazing experience begins.

For us, play isn’t a break from work. It is work, at its most powerful. Play brings team culture to the fore, speeds up collaboration and creates connections where meetings fall short.

Not because play solves everything. But because it opens up conversations that would otherwise never take place.

How does your team score in collaboration?

How does it work?

1. Ask your question.

Have a look at our range of workshops and team-building activities. Not sure what your team needs? Just ask – we’d be happy to help you find the right solution.

2. Introduction.

We’ll arrange a meeting and get to the bottom of your enquiry. What do you want to achieve? What’s going on within the team? We’ll also take into account what lies beneath the surface.

3. Customised proposal.

Based on your requirements, we’ll put together a bespoke programme within a week. Every game is tailor-made, in collaboration with our partners at the most beautiful locations in Brussels.

4. Playing and anchoring.

You’ll have adventures, laugh, clash and build. We’ll guide you and keep the goal in sight. After the fun comes reflection, so that the experience sticks in the workplace. Step by step towards better collaboration.
