• Define self-serve vs. human-touch segmentation across the portfolio.

Requirements

• 3+ years in Customer Success in a B2B environment.

• Strong data analysis skills: dashboards, churn signals, metrics-to-decisions.

• Ability to manage 200+ accounts simultaneously through systems and smart prioritization.

• Proficiency with AI tools for workflow automation.

• HubSpot experience (dashboards, workflows, automated sequences) is a strong plus.

• Experience in consumption-based or usage-based business models (not just subscription SaaS) is a strong plus.
