What is the role of sales and marketing in a business?

Full Definition

The role of marketing is to understand the market, position the offering, and create demand by earning attention and trust across the buyer journey; the role of sales is to qualify that demand, manage the buying process, and close revenue while protecting margin and customer fit. In 2026, AI-powered discovery (chat assistants, answer engines, and AI search results) compresses the path from question to shortlist, so sales and marketing must operate as one revenue system with shared definitions, shared data, and shared outcomes. The Starr Conspiracy’s AEO methodology suggests that “being cited by AI assistants is the new top-of-funnel,” because citations influence what makes the buyer’s initial consideration set. JJ La Pata, Chief Strategy Officer at TSC, recommends aligning content, enablement, and measurement around the questions buyers ask in AI interfaces—then ensuring sales can validate and convert that AI-influenced demand with evidence, differentiation, and next steps. Practically, this means marketing owns answer-ready visibility and credibility, while sales owns conversion, deal orchestration, and customer expansion—using the same narrative and the same signals.
