Cosuno is one of Europe's fastest-growing ConTech scale-ups, revolutionizing procurement and subcontractor management in construction—one of the world's largest yet least digitalized industries. We have strong product-market fit, excellent metrics, and ambitious growth targets. You will serve as Chief of Staff (Commercial Focus), working directly with the founding team and Chief Revenue Officer. This is not a pure advisory role but a builder position focused on solving complex growth challenges and driving strategic initiatives from hypothesis through successful implementation. Key Responsibilities: • Strategic Execution: Own business-critical go-to-market projects spanning Enterprise Sales, Revenue Operations, and Customer Success. • Commercial Excellence: Identify funnel inefficiencies, develop data-driven solutions, and scale revenue engines through pricing strategies, new market segments, and sales-cycle optimization. • Cross-functional Leadership: Bridge commercial teams with Product/Tech, break silos, and align all functions to exceed OKRs. • Executive Leverage: Relieve the founding team and CRO of operational day-to-day work, prepare board meetings, and make independent C-level decisions. You will work from our modern Berlin-Friedrichshain office with a hybrid option. The company offers an indefinite contract, state-of-the-art equipment, regular team events, and a highly motivated international team. Requirements: • 2–3+ years of experience from a top-tier strategy consulting firm, OR proven significant impact in a similar strategic role within a high-growth B2B SaaS environment. • Strong commercial acumen: deep familiarity with B2B software metrics (ARR, CAC, LTV, Churn) and ideally prior project experience in GTM strategy, Sales Excellence, or Pricing. • Analytical excellence: data-driven decision-making, proficiency in financial/commercial modeling, ability to translate complex issues into clear action recommendations. • Communication strength: precise, concise communication; confident at C-level and board contexts. • Languages: native-level German and excellent English.
