Who are we?  

A world where complexity is the only constant demands a new breed of company. Brave Bison is a different beast: a media, marketing and technology company purpose built for the digital era.  

 

Our universe is made up of award-winning business arms Brave Bison, Engage, SocialChain and MTM. And we’re underpinned by leading marketing training practice, MiniMBA, as well as our very own social-first media network who deliver monthly views in the billions for some of the biggest channels in sport and entertainment across YouTube, Snap, Meta and TikTok.  

 

We’re a global collective who live and breathe digital, working with some of the boldest brands in the world to capitalise on the complexity that defines the modern marketing landscape.  

 

Our mission 

 

New platforms, new behaviours, new audiences, new trends, new technologies, new regulations—our clients’ worlds get more complex daily. Their agency partnerships shouldn’t. It’s our job to cut through the chaos, make the complex simple and navigate a clear path to growth for them.  

 

That’s why we make it our mission to capitalise on complexity for our clients—across consultancy, capability and execution—by crafting dynamic digital solutions that outpace tomorrow’s challenges.  

 

Our values 

 

We’re a proudly diverse business comprised of deep specialists across media, marketing, training and technology. Although our skills, backgrounds and beliefs may differ, we are united by four core shared values: 

• Bold Curiosity. 

We run at change and challenge convention because we love to push the boundaries of what the world thinks is possible. We champion discovery, go deep into our clients’ worlds and are always hungry to learn more about them, our specialisms and each other.  

 

• Connected Clarity. 

We are focused in our collaboration — joining the right dots between our clients, our partners and our herd of experts to deliver agile solutions at speed and scale. We set a shared ambition from the outset, are transparent at every stage and always strive to make the complex simple. 

 

• Positive Encouragement. 

We want to make working with us the best part of someone’s day. We lift one other up, find the fun in the day to day and are committed to ensuring everyone belongs. 

 

• Constant Impact. 

We believe in outcomes over outputs. We’re goal orientated, results driven and data-led. We show up with passion every day. And we’re always honing our craft.
