Why this role exists
Our customers are global enterprises, and the next phase of our growth comes as much from keeping and growing them as from winning new logos. We're looking for a Head of Customer Success to own that outcome: retention, expansion and the customer experience behind both. This is a player-coach role. Roughly 70% of your time is hands-on with our most strategic accounts; roughly 30% is building and leading the team. If you want to run the function and still be the person in the renewal call, this is for you.
What you will own
Retention. Own gross and net revenue retention across the customer base. Carry a book of our most strategic enterprise accounts yourself, run their renewals and expansions, and set the standard for how every account is managed.
Playbooks. Design and run the retention playbooks: the renewal cycle, early-warning signals (adoption, champion change, procurement, competition), executive sponsorship, and value proof through ROI stories and our newer products (Learn, Cora and our knowledge-transfer agent).
Expansion. Build the CS-sourced expansion motion with Sales: seats, new teams and new products inside existing customers, with clear triggers, plays and hand-offs.
Operating system. Be the business owner of our AI-native customer success platform: health scoring, risk and expansion signals, forecasting, and a weekly view of the book for the executive team.
Team. Lead and coach Customer Success Managers, hire another for the team, and design how our next stage of Enterprise growth is covered, from high-touch enterprise accounts to a digital-led long tail.
Voice of the customer. Bring what customers need back to Product and Marketing, and turn customer outcomes into stories the whole company can use.
Who you are
Must haves
7+ years in Customer Success or post-sales at a B2B SaaS company, including time leading a team or running a function as a player-coach.
Experience at a seed, Series A or Series B startup: you have built or scaled a CS function with limited resources and know what good looks like at this stage.
