About

Operators since 2011.

The people who diagnose the problem are the people who build the system. We've worked with more than 90 businesses since 2020, including private equity portfolio companies from the first 100 days through to exit, and our founders have built and sold two businesses of their own. We know what growth has to prove to a board and an acquirer.

Our story.

Aimee and Mark Engelmann started Flipside in 2011 as a marketing business in Queensland. In 2014, while running Flipside, they also founded Beepo, a BPO business, and scaled it through to its acquisition by private equity-backed Probe CX in 2019.

That experience shapes the work. We have sat on the other side of the board table, and we know a growth story only holds up when the systems behind it do. Since 2025, Flipside has brought strategy, process, CRM and automation together into one growth system.
