"I'm incredibly excited to join Circles.Life at this point in the business' journey, building on the success to date, and putting the customer front and centre. Circles.Life does for telecommunications what neo-banks did for banking by using technology and agility to deliver a customer-centred, frictionless experience," said Retzlaff.

"This is especially appealing to young Australians, the digital natives, who expect flexibility, such as no lock-in contracts, and transparency, such as real-time, in-app visibility of their data usage. We've seen the rise of the neo bank, now it's telco's turn. Circles.Life is here to change the game and our current offering is just the beginning."

She joins the company from Integrity Life, where she worked as general manager of marketing and customer experience for three years.
