Brennan secures investment from Macquarie

Brennan has received an investment by Macquarie Group’s principal investment arm, Macquarie Capital Principal Finance.

The amount of the investment was not disclosed.

Brennan claims to have grown its revenue at an average of 21.5 per cent per annum over its 28 years of operations and now has over 1,000 team members as part of the company.

Founder and MD of Brennan, Dave Stevens, who remains at the helm of the business and the majority shareholder, said the investment marked a major milestone in the evolution of Brennan and would "reinforce its position as Australia’s largest sovereign systems integrator".

“Through Macquarie’s support, we expect to continue our focused growth trajectory by making significant strategic acquisitions and continuing our investment in cutting-edge sovereign capabilities in AI, automation and cybersecurity,” he said.

“As well as improving our ability to bid for and win large Australian government and private sector contracts, Macquarie’s involvement also provides us with the opportunity to explore international growth opportunities, meaning we could finally see Australia compete on the global systems integrator stage.

Chair of Brennan’s board of directors, Brendon Cook, said Macquarie’s investment was a "transformative step" for Brennan.

“It not only strengthens the company’s balance sheet but is also important for our vision and growth strategy which we will continue to deliver on with the commitment and leadership that has shaped Brennan’s success to date,” he said.

“Macquarie’s support will allow us to scale at an even faster rate, further integrating secure AI- driven solutions that will empower our customers."

In 2025, Brennan acquired Canberra-based cybersecurity, connectivity and cloud specialist CBR Cyber; announced a scale-up of its WA operations; announced partnerships with TasPorts and LogicMonitor; was awarded a multi-year contract by the National Capital Authority; and promoted Peter Soulsby to director of cyber security alongside the addition of three new hires.

Stevens was also a guest on the techpartner.news podcast, where he talked through a range of factors that he and his peers consider when they are looking at potential acquisition targets beyond region and vertical specialty.
