SKILLS
ABOUT NICOLAS MAXIMILIAN ROESSLER
I am an international commercial leader and Key Account Manager with a track record across specialty materials and hospitality—today focused on high-performance adhesive and sealing technologies for global automotive OEMs and Tier-1 suppliers.In my current role at Sunstar Engineering, I manage strategic key accounts and drive complex international customer programs with meaningful annual and lifetime revenue impact. I act as the primary interface for commercial, technical, and strategic topics across the full value chain (R&D, production, engineering, purchasing, quality). I develop TCO calculations and customer-specific business cases to support negotiations and strategic decisions, and I work closely with global R&D and manufacturing teams to develop, qualify, and industrialize solutions across 1K/2K PU, SMP, hotmelt, PSA, and paint-shop applications. I also build a sustainable opportunity pipeline, including localization and production setup strategies.Previously at Bostik, I held €18M revenue responsibility as Area Sales Manager for PSA across Germany, Poland, and Benelux, covering multiple PSA technologies. I owned key account management, new customer acquisition, pricing, complaint management, forecasting/budgeting, and product launches, reporting directly to the Sales Director EMEA.Before that, I spent four years at Absortech Group as Key Accounts & Area Manager for Germany/Austria, Eastern Europe & Russia, leading a network of 11 distributors across multiple countries and owning international business development, strategic sales and marketing planning, budgeting, and global event execution. This strengthened my ability to build markets, align partners, and adapt commercial strategy to diverse regional dynamics.Earlier in my career, I developed strong B2B sales discipline and customer-experience leadership in international hospitality roles (Marriott, Radisson, Hilton, Nira), including account management, contract negotiation, prospecting, team development, and operational execution—capabilities that translate well into complex, stakeholder-rich B2B environments.I am known for a structured, data-driven and proactive approach, combining relationship building with commercial rigor and cross-functional leadership—from opportunity identification to industrialization and long-term partnership growth.Focus areas: Key Account Management (OEM/Tier-1)| Technical & Solution Selling | Pricing & Negotiation | TCO/Business Case Development | International Growth & Distributor Management | Portfolio/Market Development
