Yanis Varoufakis describes himself as a "libertarian Marxist," although, he says, "It is not something that I volunteer to talk about much, because the very mention of Marx switches audiences off." He teaches economic theory at the University of Athens, where he challenges mainstream notions -- arguing that after the financial crash of 2008 we need a radically new way of thinking about the economy, finance and capitalism.

He became widely known in the first half of 2015 when, as Minister of Finance of the newly formed Greek government, he was a leading, outspoken and much-discussed figure in the renegotiations of Greece's debt.

In May 2017, Varoufakis released Adults in The Room: My Battle With Europe’s Deep Establishment, a personal account of Europe's hidden agenda and an urgent wake-up call to renew European democracy.
