Strategic Customer Success Manager

About Us STACK is a leading provider of cloud-based construction estimating and takeoff software, committed to helping businesses transform how they work. We pride ourselves on fostering a collaborative, dynamic environment where team members have the opportunity to grow and make a real impact. About the Role STACK is looking for a Strategic Customer Success Manager to own a named book of our largest and most complex customer accounts. You'll be the primary relationship owner for multi-seat and enterprise customers – general contractors, specialty subcontractors, and preconstruction teams that run their bidding and estimating on STACK. You own renewals, expansion, and adoption across your book, and you're the voice of these customers inside STACK. You'll report to the Manager, Customer Success, and work alongside the pod that covers our pooled single-seat accounts. The Enterprise motion is still taking shape, so the account plans, health signals, and business reviews you build will set the standard for how STACK runs named coverage. What You'll Do Named Book Ownership – Own a book of named accounts end to end: the relationship, the renewal strategy, and the expansion motion. Executive Relationships – Build relationships beyond the day-to-day user. Know the owners, directors of preconstruction, and executive sponsors who make the buying decisions. Renewals & Retention – Own gross and net retention for your book. Start renewal conversations early, spot risk before it shows
