In 2017, Mick Liubinskas got one line from an old basketball mate: "maybe it's time you got in the game." He'd just moved to the US, read the IPCC reports for the first time, and had three kids under seven. But he couldn't unsee it, so he got in the game.

Nine years on, Mick leads Climate Salad - a community of 800 Australian climate tech founders and operators that he deliberately chose to keep lean when it could have grown. He knows the funding volatility, the long hardware timelines, the challenge of selling Australian innovation to Australians who'd sooner trust the same thing from a US startup. But when three founders in the same week told him their sales cycles were getting shorter, he almost cried.

What this conversation gets into is the tension in climate tech right now: how do you hold genuine conviction about an existential problem while speaking a language that CFOs, customers and markets can actually act on? And what happens when you finally make peace with what kind of builder you actually are instead of the one you assumed you were supposed to be?

Kate sits down with Mick to talk about why he walked away from a tech career to work on climate, what he learned from building and deliberately shrinking a community, the one leading indicator that tells him the tide is turning, and what he changed his mind about.
