After 77 episodes and eight years at Blackbird, Mason Yates is signing off as host of Wild Hearts. This is his final episode - just eight minutes, no fanfare and true to how he hosted: generous with the floor, light on his own voice.

Mason started Wild Hearts in 2020. Lockdown. Sourdough. Tiger King. Across the six seasons since, Mason has sat down with founders building mind control for cows, sending toaster-sized satellites into orbit, and chasing a million-qubit quantum computer. Holding the mic through the 2021 supernova, the 2022 correction, the survivor years, and the deep tech wave defining this moment.

There's one question he's asked nearly every founder along the way: what gives you the most energy? In this episode he walks back through the answers that have stayed with him - Melanie Perkins, Tim Doyle, Tom Kelly, Flavia Tata Nardini - and shares three lessons from 77 episodes on the craft of interviewing.

And then he hands the show over to Kate Glazebrook.

If you've been listening since 2020, this one's a love letter to the archive you helped build. If you're new, it's the perfect doorway in.

Thank you, Mason. From all of us.
