Interim Head of Marketing – Travador

Travador was at a point where marketing budgets, channel priorities, and overall profitability logic needed to be fundamentally reassessed. The objective was clear: stabilize revenue while significantly improving the profitability of marketing activities.

Execution & Impact

  • Refocused on high-margin channels such as email and affiliate/partner marketing
  • Reworked budget allocation, discount structures, and campaign planning
  • Led and structured the marketing team to ensure clear ownership and accountability
  • Introduced and scaled new channels and initiatives, including WhatsApp, HubSpot, the mobile app, and the Travador Club

The result was a more performance-driven setup with clearer economics and stronger contribution margins.
