Jeremy Heimans is co-founder and CEO of Purpose. He is an Australian-born political activist and a co-founder of GetUp and global online political community Avaaz.org.

In this TED Talk Heimans presents a case that something fundamental has changed in the world and it’s not just about ‘new tech’. There has been a shift in power; a move from Old Power to New Power.

Heimans uses the example of Anna Hazare, a peaceful 77 year old, Indian social activist who led a powerful campaign to address corruption in India. Using mobile activism, Hazare deployed a simple tactic : “leave me a missed call”. This resulted in 35 million people leaving Hazare a missed call, thereby giving him a massive data base of people to mobilise in peaceful street protests. This is the largest technological call to action in the world.

Heimans talks about a fundamental shift in the balance of power in the world and by using examples from Uber, Airbnb, Kickstarter and Apple he asks us ‘how do we use institutional power without becoming institutionalised?’ This is a question that every radical and activist will need to address in order to bring about the shifts we require in health and social care across the world.

I was greatly cheered on by his closing call to Occupy Yourself before others occupy you !
