Senior Strategic Finance Manager, B2C Marketing

Preply

Senior Strategic Finance Manager at Preply leading finance for B2C marketing economics. Owns financial modeling and fosters executive reporting for growth initiatives.

Posted 6/22/2026full-timeLondon • 🇬🇧 United KingdomSeniorWebsite

About the role

Key responsibilities & impact
  • Lead the B2C marketing economics domain across modelling, forecasting, business partnership, and executive reporting.
  • Define the right questions before answering them. Frame the investment problem, not just the financial output.
  • Act as the senior Finance voice in Growth Marketing planning forums, challenging assumptions and landing decisions with credibility.
  • Own the B2C marketing financial model across paid acquisition (SEM, paid social), organic and brand, with full accountability for forecast accuracy.
  • Maintain and evolve the model connecting marketing inputs to subscriber acquisition, retention, and LTV.
  • Lead monthly and quarterly forecasts; own the variance narrative with clear driver decomposition.
  • Build the models that stress-test ROI assumptions under different investment, competitive, and macro conditions.
  • Build and own the framework that quantifies the relationship between paid spend levels and organic search performance, understanding halo effects, cannibalization, and the true blended cost of acquisition.
  • Work with BI and Growth to define and track incrementality, ensuring our financial model accounts for inter-channel relationships correctly.
  • Identify the point at which marginal paid investment stops generating efficient organic lift, and use this to inform budget allocation decisions.
  • Lead the financial analysis behind geo expansion decisions — sizing the opportunity, modeling the investment required, and setting the return thresholds that make a market worth entering.
  • Partner with Marketing on go-to-market planning for new geographies: channel mix assumptions, ramp curves, payback timelines, and break-even horizons.
  • Build the reporting framework that tracks new market performance against investment thesis, with clear triggers for scaling up or pulling back.
  • Build and own the investment framework the Growth team uses to evaluate channel and campaign decisions — clear decision rules, ROI thresholds, and payback criteria that enable speed without sacrificing discipline.
  • Define the financial guardrails within which Growth can act autonomously: spend limits, efficiency floors, and escalation triggers for decisions that need Finance sign-off.
  • Act as the Finance partner on material marketing spend decisions; identify major swings against budget and adjust forecasts in real time.
  • Constantly iterate on model accuracy, partnering closely with the Growth team to stay current on latest learnings from incremental and media mix modeling and attribution models.
  • Prepare and own materials for CMO and CFO-level reviews, translating model outputs into clear, action-oriented narratives.
  • Build and pressure-test the financial cases behind major marketing bets: channel shifts, brand investments, incremental spend decisions.
  • Partner with BI on KPI frameworks, ensuring financial and operational metrics are consistent, reconciled, and trusted.
  • Lead the B2C marketing workstream in the AOP and LRP cycles, owning both the numbers and the strategic assumptions behind them.
  • Conduct rigorous channel-level analyses: CAC, LTV, payback periods. Benchmark against market comparables to sharpen investment logic.
  • Identify and escalate risks and opportunities in the acquisition funnel before they hit the P&L.
  • Actively use AI tools to automate repetitive analyses, accelerate model builds, and reduce manual reporting time.
  • Work in Looker and Excel/Google Sheets to interrogate data independently
