What you'd actually do

  1. Lead and develop your team. Coach a team of Account Development Managers through structured 1:1s, call reviews, and account strategy sessions that drive real behavior change. Set clear standards for what great looks like across prioritization, customer engagement, expansion strategy, and follow-through, and hold the team to them. Hire and ramp new ADMs with clear expectations from day one.
  2. Own your team's performance. Drive consistent attainment of expansion goals by tracking pipeline health, conversion rates, and leading indicators, then turning those insights into practical coaching plans. Keep expansion opportunities moving and step in when needed to unblock progress, reset momentum, or support high-stakes accounts directly.
  3. Shape strategy and the go-to-market playbook. Define how the team identifies, prioritizes, and engages high-propensity accounts using product-usage data, lifecycle triggers, and predictive scoring. Continuously refine the balance between scalable one-to-many campaigns and high-touch engagements for top-value opportunities.
  4. Lead cross-functionally. Serve as the primary Account Development voice with Product, Marketing, Data, and Revenue Operations, synthesizing customer feedback into actionable insights that influence roadmap and strategy, and partnering with Account Management Leadership to improve workflows and tooling as the team scales.
