Leadership background

Why this matters for GTM teams

Executive appointments can precede changes in strategy, operating cadence, hiring, partnerships, and technology priorities. The useful signal is not the title alone: teams should watch the new leader’s stated mandate, prior playbook, organizational scope, and the initiatives announced during the first two quarters.
