How a Bondi dad is taking on the giants of the toxic cleaning aisle

Open the cupboard under your kitchen sink. Chances are you’ll find a dozen or more cleaning products, each with a slightly different job and nearly every one carrying a warning about the chemicals inside.

Koh co-founder Adam Lindsay didn’t set out to build a brand people would talk about. He set out to solve a problem in his own cleaning cupboard, and ended up building one of Australia’s most trusted cleaning brands almost entirely on word of mouth.

In this episode, Kiarne sits down with Adam to talk about what it actually takes to earn that kind of trust, from a cold call to a university chemistry department, to farmers market stalls, to nearly two million households today. It’s a conversation about taking on the giants of the cleaning aisle with a safe and sustainable product, and winning.  

You’ll hear and learn:

This episode is a must-listen for anyone who’s ever stood in the cleaning aisle wondering which claims to trust, and any founder wondering whether doing things properly is worth the extra cost.
