THE BRIEFING

Enterprise Strategy Briefing™

The firm’s monthly publication, at the intersection of enterprise strategy, finance, and operations

Each issue is a curated brief for the senior leaders of midmarket organizations—a short selection of developments worth an enterprise leader’s attention, with the firm’s commentary on what matters and why. A typical issue runs ten slides or fewer and is delivered by email monthly.

The Briefing is intentionally short, built for the leader running a real company. It does not cover every story—it covers the developments that, in the firm’s view, deserve the attention of leaders at the principal’s table.
