Performance Reporting & Analytics

• Design and own the commercial KPI framework including ARR, NRR, churn, CAC, LTV, payback period and unit economics
• Deliver monthly commercial performance packs for the Executive Leadership Team and Board
• Build automated, self-serve dashboard reporting where possible to reduce manual effort and increase insight quality to ELT
• Conduct ad hoc deep-dives into commercial performance topics such as cohort analysis, pricing elasticity and segment profitability

Strategic Finance & Investor Relations

• Strong experience partnering with Sales, Marketing or commercial leadership teams
• Deep understanding of SaaS or subscription business metrics (ARR, NRR, churn, pipeline conversion, unit economics)
• Advanced Excel and financial modelling skills; comfortable building models from scratch
• Experience with revenue forecasting, pipeline analysis and variance reporting
• Proven ability to influence senior stakeholders and deliver insight that drives decisions, not just reports
• Ability to translate complex financial analysis into clear, actionable insight for non-finance stakeholders
• Strong written and verbal communication skills – able to present to senior stakeholders and the Board clearly and confidently
• Collaborative working style with a genuine interest in understanding the commercial context behind the numbers
