Big ideas can change the world. Join us to witness inspiring speakers and performers (chosen from thousands of applicants) sharing world-changing ideas.

The TEDxMileHigh community is rooted in Denver and Colorado, but extends across the globe through our online community. TEDxMileHigh RETHINK will bring together – LIVE and IN-PERSON – thousands of curious and engaged thinkers, creators, and activists.

We are a non-profit organization that showcases Colorado’s leading thinkers and doers to accelerate big ideas and the community impact that follows. Our talks have been viewed more than 115 million times online across the globe. 

TEDxMileHigh: RETHINK is an immersive experience that extends inspiration beyond the stage. You may check out emerging technology at our exhibits lounge, dive deeper into a big idea at one of our conference Adventures, or flex your mindfulness muscles at a community yoga class. 

Let us RETHINK what is possible.

Let us challenge the boundaries we’ve set for ourselves. Let us revel in our imagination to contemplate an entirely new future.

The last 18 months have changed the world. Public health, government, finances, technology in various realms – have all changed. Our old way of thinking is obsolete. It’s time to rethink the future.

Join to hear from our community of activists, entrepreneurs, innovators, researchers, and artists who are passionate about rethinking the impact our lives will have. 

We are a place for you to tap into new big ideas, connect with like-minded individuals, and be a part of a movement to catalyze progress.
