Reach people who make things.

Overtone listeners are designers, engineers, scientists and makers who choose a long conversation over a short one. We take a few sponsors per season and read every ad ourselves.

        Read by the hosts. Never by a robot.

        We only advertise things one of us has used. If we wouldn’t recommend it to a friend, we’ll say no.

        “I’ve been using Ferncroft notebooks since season one. The dot grid is the right grey. Nadia disagrees, loudly.”
