• Collaborate with engineers to translate customer requirements into Fin solution designs, guiding the customer on configuration best practices and prompt strategy.
• Monitor Fin usage patterns to identify risks, recommend optimizations, and uncover expansion opportunities. 
• Maintain deep product knowledge of Fin’s fast-expanding capabilities; remain market aware of the fast evolving AI-agent industry.
• Lead Success Plans, QBRs/EBRs, and strategic planning sessions with executive stakeholders hold yourself and your customers accountable to clearly defined milestones and measurable outcomes.
• Quantify and communicate customer value through ROI metrics, outcome narratives, and executive briefings — building compelling business cases for continued and expanded investment.
• Partner with Sales and Renewals to protect GRR, drive growth and progress further exposure of Fin to our customers' challenges. 
• Prioritize competing demands to drive the highest-value outcomes across your customer portfolio.
