Buy informed, not hopeful

fossie is a marketplace scout. It watches Facebook Marketplace for the things you're after and gives each listing plain-language AI guidance with a traffic-light score.

Alert and monitor only. It never buys, bids or messages sellers for you.

How it works

Three steps, no pressure. You make the call.

  1. Tell it what you're after

    A bike, a bookcase, a barely used air fryer. Say what you want and where you are.

  2. It watches new listings

    fossie keeps an eye on Marketplace so you don't have to scroll it every morning.

  3. You get a score and a note

    A traffic light and a short, honest note on each one. Then you decide.

A verdict you can read at a glance

Every listing gets one of three, always with a word, never just a colour.

Fossick your way to a good find

The name comes from fossick, Aussie slang for rummaging around for something good. Fossie the bowerbird is your guide: a mate who knows what a fair price looks like.

Coming soon

fossie is in a small invite-only alpha with family and friends. A public version is on its way.
