About Ulla-Maija

I bring B2B brands to life — strategically and in execution. As an Interim Marketing Lead, I support companies in mobility, energy, and transformation in translating complex topics into clear narratives, shaping markets, and building thought leadership that truly resonates.
My strength lies at the intersection of strategy, brand, and communication: I develop positioning that endures, build formats from scratch, and bring projects to completion independently — from the initial briefing to measurable impact.
Most recently, I spent over five years at mobile.de building the mo:re conference: a B2B future format for the automotive industry, which grew to 1,000 attendees. Before that, nine years of brand and campaign responsibility at MINI and BMW Germany.
I take on projects in the areas of B2B Marketing Strategy, Brand Development, Thought Leadership, Content & Campaigns, as well as Event and Community formats — remotely, hybrid, or on-site in Berlin.
