Young Difference Makers: Excel is eating audit, and Christiaan Coetzee brought the fork!

Ready to discover how a chartered accountant turns risk literacy into a founder’s edge? We sit down with Christiaan Coetzee—CEO and co‑founder of Audit Toolbar and SAICA Top 35 Under 35 overall winner—to unpack the mindset shifts and practical levers that help small firms run with the giants. Christiaan shares how starting articles straight out of high school gave him a front-row seat to hundreds of businesses, and why governance, financial fluency, and rapid risk assessment can be superpowers when you’re building something new.

We dive into the surprising centre of gravity in audit work: Excel. While big platforms chase grand architectures, most auditors still spend the bulk of their time inside spreadsheets. Christiaan’s team built a tool that lives where the work happens, unlocking “insane efficiency gains” and levelling the field for five-person practices competing with enterprise players. The results speak loudly: a rolling 650 years of work saved across Africa every year, letting local firms grow faster, pitch bigger, and serve clients better.

The conversation turns on a simple but uncomfortable truth—most of us think too small. Christiaan describes the shock of hearing peers make fearless asks of global leaders and realising he’d been self-rejecting big opportunities. His new default is to pick up the phone, pursue top-tier clients, and let the answer be earned, not imagined. Along the way, he lays out a grounded operating system: protect your work ethic, mentor the next builder in line, and prioritise cash moving hands—funding for impact orgs, revenue for startups. Forecasting tech beyond two years is murky, but staying close to customers and their real levers keeps you ahead where it counts.

If this resonates, follow the show, share it with a friend who’s thinking small, and leave a review telling us the one bold ask you’ll make this week.
