About 100Marketing

Most B2B companies buy marketing like a service: briefing in, output out, invoice paid. Individual campaigns, no red thread, no measurable results – not because the measures were bad, but because nobody took responsibility for the outcome.

We do it differently. 100M takes over marketing leadership – strategically and operationally. We analyze, position, set up, and measure everything against what really counts: qualified pipeline, company value, and sustainable growth. As an external operating partner. Not as a workshop.
