West Monroe ditches the slide deck for bespoke AI prototypes

Since shifting to an app-first strategy in January, the firm has introduced working demos in roughly one-third of its first client interactions. By utilizing tools like ChatGPT, Claude Code, and Google AI Studio, consultants have slashed prototype development time from eight weeks to about an hour. This rapid iteration allows teams to build tailored interfaces that use client-specific branding and synthetic data, effectively collapsing the gap between a theoretical proposal and a tangible proof of concept.

This approach forces immediate engagement with the realities of implementation, such as data quality and workforce integration, rather than abstract discussions about AI capabilities. With an internal library of over 700 templates, the firm reuses successful framework components, adjusting them incrementally for new clients. Greenstein notes that this pivot is fundamentally about prioritizing measurable outcomes over the technology itself, treating the demo as a test drive rather than a static presentation.
