About Ulla-Maija

Ich bringe B2B-Marken in Bewegung — strategisch und in der Umsetzung. Als Interim Marketing Lead unterstütze ich Unternehmen in Mobility, Energy und Transformation dabei, komplexe Themen in klare Narrative zu übersetzen, Märkte zu gestalten und Thought Leadership aufzubauen, der wirklich wirkt.
Meine Stärke liegt an der Schnittstelle von Strategie, Marke und Kommunikation: Ich entwickle Positionierungen, die halten, baue Formate von Null auf und bringe Projekte eigenverantwortlich zum Abschluss — vom ersten Briefing bis zur messbaren Wirkung.
Zuletzt habe ich bei mobile.de über fünf Jahre die mo:re-Konferenz aufgebaut: ein B2B-Zukunftsformat für die Automobilbranche, das auf 1.000 Teilnehmer:innen gewachsen ist. Davor neun Jahre Brand- und Kampagnenverantwortung bei MINI und BMW Deutschland.
Ich übernehme Projekte in den Bereichen B2B Marketing Strategy, Brand Development, Thought Leadership, Content & Kampagnen sowie Event- und Community-Formate — remote, hybrid oder vor Ort in Berlin.
