As they seek to build Australia's most advanced agentic AI business, Lendi's AI team is transparent about the fact that genuine transformation is messy and frought. For instance, agentifying its flagship home loan process (codenamed Guardian) was an at times bruising, highly commercial education in what agentic really is and what it definitely isn’t. Executives have outlined a number of crucial lessons they've learned, including one of the real unlocks: Agents must be trained to sell, not just to answer. Lendi shipped a “beautiful” agent with bad outcomes, because it asked for documents too early and never demonstrated value. The fix wasn’t just better prompting. Instead, it was sales logic in the funnel, specialist agents up front, and relentless measurement. These are the Guardian lessons in full: unlearn the old ways, design the agent workforce like a business, keep the plumbing deterministic, put value before friction, and treat governance as a product feature, because without it, your Mozart-like swarm turns into Trump, and you won’t know what it’s doing from one minute to the next.
