Lead-to-Revenue Architecture.
„Translating marketing spend into validated sales revenue."
Strategic Lead-to-Revenue Architect focused on repairing complex lead infrastructures and translating marketing spend into validated sales revenue. Not a traditional CMO for global brand strategies, but a specialist who systematically eliminates inefficiencies in the lead-to-revenue chain. The approach is data-driven and leverages cutting-edge tech stacks, proven by ongoing international mandates including Canadian and US markets. Particular strength in establishing psychological conversion frameworks and transforming agency project business into recurring revenue (MRR). Delivering hard KPIs: direct SQL rates of 25% and CPQL reduction of 35%.
What clients say.

„David Kosfeld supports us as a freelance SEA consultant with a very pleasant, relaxed and at the same time strongly goal-driven collaboration. On his own initiative, he repeatedly contributes new ideas and concrete improvement suggestions and looks at our company strategically from a bird's-eye view. Professionally, he is a real added value: He is always up to date in online advertising, implements trends early and has delivered significantly better results than previous agency partners – with many high-quality leads at optimal cost per lead and cost per qualified lead. We recommend David without reservation."
