ABOUT US

Here for
a reason:

The Australian creator economy needed a consultancy that took both sides of the table seriously. So we built one.

OUR STORY

After nearly a decade in PR and brand communications, our founders kept seeing the same problem: talented creators without the right support, and brands investing in partnerships that never reached their potential.

Star & Sigma exists to close that gap. We specialise in tech and lifestyle talent, and we work hard on both sides of every partnership — so creators can grow on their own terms, and brands actually get what they came for.

THE FOUNDERS

Maddy Grey

CO-FOUNDER, STAR & SIGMA

Maddy brings the strategic rigour and brand-side expertise that makes creator partnerships actually perform — having led major campaigns across some of Australia's most recognised technology brands.

Liam Bettinson

CO-FOUNDER, STAR & SIGMA

Liam brings the commercial instinct and creator-side experience that makes campaigns come alive — with a track record building and scaling programs for leading global brands.

THE NAME

The Star represents the creator. The Sigma — independent, self-made, operating outside the expected — represents the mindset. Together, a new model: built on individuality, clarity and measurable impact.
