• Own a portfolio of accounts end to end, serving as the primary commercial point of contact responsible for retention, gross renewal rate, and expansion within your book. • Lead the full renewal lifecycle — from early health/risk assessment and stakeholder alignment through proposal, negotiation, and close — ensuring a high gross renewal rate. • Partner closely with Measurement Strategy counterparts to translate experiment and cMMM insights into clear commercial value narratives that support renewals and expansion. • Identify, qualify, and close expansion opportunities across your accounts, including upsells into cMMM and net-new Haus products as they launch. • Develop a deep understanding of each customer’s business model, media strategy, and measurement maturity to proactively surface new use cases and value-add recommendations. • Run regular business reviews (e.g., QBRs/EBRs) with senior stakeholders, telling a compelling story about impact, learnings, and where to invest next with Haus. • Maintain accurate account plans, forecasts, and pipeline in our CRM; provide clear visibility into renewal and expansion performance against quota. • Collaborate cross-functionally with Sales, Measurement Strategy, Product, CX, and Marketing to unblock customers, manage escalations, and bring the best of Haus to every account. • Systematize what works by contributing to playbooks, collateral, and repeatable motions for renewals, expansions, and cMMM upsells across the GTM team. • Serve as the voice of the customer back into Haus, synthesizing feedback and partnering with Product and CX to shape our roadmap and service model.
