Is This Role For You?

For You If
  • You've scaled B2C SaaS, apps, or subscription products from early traction to meaningful revenue
  • You understand mobile monetization (paywalls, freemium logic, pricing, upsells) and can challenge product choices with revenue data
  • You own full-funnel thinking—from brand positioning through CRM lifecycle—and see them as interconnected, not siloed
  • You're comfortable in ambiguity and bias toward experimentation; you ship fast, measure rigorously, iterate
Won't Work If
  • You're a pure brand marketer uncomfortable with metrics, P&L accountability, or ruthless prioritization
  • You need a large established team immediately; this is a build-and-scale role requiring scrappiness
  • You don't speak or want to learn the language of product, pricing, and monetization mechanics
