The Microsoft CELA announcement is more than a vendor win for Harvey — it is the clearest data point yet on what enterprise-scale in-house AI adoption looks like. A 2,000-person legal and compliance team operating globally has selected a single specialized AI platform, integrated into its existing productivity infrastructure (Microsoft 365), running on its own cloud (Azure), with data that stays inside Microsoft's security perimeter. For legal tech operators building for the in-house market, the CELA model establishes the enterprise procurement template: security perimeter control, integration with existing infrastructure, specialized legal intelligence layered on top of general-purpose tools, and enterprise agreements rather than per-seat SaaS pricing. Harvey's reported ~$1,200/seat mid-market pricing falling to $100–200/seat at 200+ seat deployments suggests the enterprise market is large enough to support that model.
