The spark behind the purpose

Why telling your brand story matters.

Cornerstone was founded by Kayleigh Kahlefeldt with one clear mission: to build powerful, exciting brands that cut through the noise and connect. After a career spanning international PR, global creative agencies, and corporate marketing leadership, Kayleigh saw a common thread: the most magnetic brands weren’t the loudest or the biggest. They were the ones with a clear sense of self and something meaningful to say. 


At Cornerstone, we exist to help brands uncover their essence - who they are, what they stand for, and how to express it in a way that’s bold, brilliant, and impossible to ignore. We don’t just produce creative content; we craft brand identities that feed and grow highly engaging marketing strategies. Because when you build a brand on a rock-solid foundation, everything else falls into place - and takes off.

"My branding and content strategy session with Cornerstone Content Australia was amazing! Kayleigh turned my thoughts and dreams into a clear strategy and is now implementing these for me each week. Thanks so much Kayleigh Kahlefeldt, you've freed up so much headspace for me!"


Kristie Jenkins Travel Managers

The Cornerstone team were first class in all respects (scoping, design, build, delivery and customer support). Not only did the team build a world class website as validated by my followers (over 21k views in the first 3 days!) but this was achieved within a very tight timeframe and budget.
