JANA Investment Advisers (JANA) is pleased to announce the appointment of Zac Leman as General Manager, Wealth.

Zac’s appointment reflects strong growth and momentum in JANA Wealth, with total wealth client funds under advice or management of ~A$15bn, including more than A$3.4bn in managed accounts. It also underscores JANA’s continued investment in senior leadership to support scale, innovation and strong client outcomes.

The appointment comes at a time of significant structural change across the wealth and advice sectors, as clients increasingly seek institutional-quality insights to meet growing portfolio, governance and implementation complexity.

This move reinforces JANA’s ongoing focus on expanding its wealth capability, building on sustained growth and long-established expertise across advice, research, portfolio construction and implementation.

Zac will lead JANA’s Wealth business strategy, strengthening advice, investment, operational and implementation capabilities to support continued growth in the Wealth segment. Michael Karagianis will continue to lead JANA’s Wealth consulting relationships.

The appointment follows the recent strengthening of JANA’s investment leadership with the appointment of Matt Wacher as Chief Investment Officer, reinforcing alignment across investment strategy and client delivery as the business continues to scale.

Lauren O’Neill, General Manager, Strategy & Innovation at JANA, said: “Zac’s appointment strengthens our leadership at a time when clients are seeking more sophisticated, institutional-quality capability that’s delivered to meet their needs. Drawing on his deep understanding of the wealth and advice landscape, Zac will play a key role in expanding access to our investment expertise, and delivering consistent, high-quality advice and implementation outcomes.”

Zac Leman said: “JANA’s client-first philosophy, purpose-led approach and its depth of investment capability strongly align with how I think about delivering value to clients. The business has built real momentum in the wealth segment, and I’m excited to be joining at a time of opportunity and growth.

The wealth sector continues to evolve, with increasing demand for more sophisticated, outcome-focused solutions. I’m looking forward to working closely with clients and partners to build on JANA’s strengths and deliver advice and implementation that supports long-term value creation.”

Zac was most recently Head of Managed Accounts and Direct Equities at BT Financial Group and has also held senior roles at Mason Stevens and Next Financial. He officially commenced his role at JANA on 4 May 2026.
