How One Firm Built AI for 90,000 People at 1% of the Price

What happens when a global firm refuses to pay $32 million a year for Microsoft Copilot? You build your own — and apparently you do it pretty well. Marsh McLennan's LenAI is now running 2 million AI requests a month across 90,000 employees, saving teams 8 hours a week. That's an entire working day reclaimed. This episode breaks down how they did it, why data privacy was the first concern, and what the build-versus-buy debate really teaches us about enterprise AI. Spoiler: it's not about having 300 engineers on staff. The bigger lesson is that purpose-built AI wins. Whether you're a global professional services firm or a growing HR team, the tools designed for your exact workflow will always beat the generic alternatives. And for hiring specifically, you don't have to build anything yourself to get that advantage. AI HR Daily is brought to you by OVI — purpose-built AI for recruiting. Audio chats, candidate screening, and smart hiring tools starting at $99 a month.
