# Vantage Partners

**Role in this source:** The author's affiliation and the practitioner base of the article's insights. Vantage Partners is a global consultancy specializing in complex negotiations, alliances, and customer/supplier relationship management — a spin-out from the [[entity-harvard-negotiation-project|Harvard Negotiation Project]] community.

**Relevance in this vault:** [[entity-danny-ertel|Danny Ertel]] is a partner here; the firm's client engagements are the implicit source of the case examples (the global oil-and-gas company's [[concept-business-plan-mandate|business-plan mandates]], the outsourcing-contract [[concept-internal-side-deals|side deal]], etc.). It links the article's practice orientation back to interest-based negotiation theory.
