• Identify retention, expansion, and churn patterns to create scalable systems
• Enable the wider CS team to become increasingly self-sufficient

Who You Are

• You have prior startup experience or have worked in high-intensity, ambiguous environments

• You think commercially and take accountability for revenue outcomes
• You instinctively spot opportunities for automation
• You can engage directly with customers when neededYou move fluidly between customer problems, data analysis, workflows, and technical systems
• You prefer ownership and ambiguity over established playbooks

Success Metrics
