# Ecosystem Synergies

**Definition:** Value created through a novel combination of the acquirer's and target's ecosystem positions that improves the merged firm's cooperation with third-party complementors.

Ecosystem synergies represent a paradigm shift in how value is created during an acquisition. Traditionally, M&A synergies are **internal**: reducing redundant costs, combining intellectual property, or increasing market share — the world of [[concept-resource-based-ma]]. Ecosystem synergies, by contrast, are **external**. They are the value created when combining two firms' ecosystem positions prompts [[concept-complementors]] (third-party developers, data providers, agent platforms, integration partners) to cooperate more richly with the merged firm.

To realize these synergies, the components of the multiple parties involved must be **interoperable and well-integrated**. The realization of value relies on anticipating new opportunities that emerge when two separate ecosystems are combined, prompting external actors to invest in new integrations, applications, and innovations.

The guiding principle, stated verbatim by the authors, is captured in [[quote-guiding-principle-synergies]]. The mechanism is operationalized into three flavors by the [[framework-three-types-ecosystem-synergies]] (Strengthening, Attracting, Connecting) and pursued via the target-selection heuristics in [[framework-strategies-pursuing-synergies]].

Because this value depends on the autonomous choices of outside actors, it carries a distinct execution-risk profile — see [[claim-ecosystem-value-external]] and the investor guidance in [[action-distinguish-valuation-sources]].

**Enrichment note:** The underlying Strategic Management Journal paper defines ecosystem synergy along the same lines and is the strongest scholarly support for this concept. The closest antecedent in the literature is Feldman & Hernandez's synergy typology (relational, network, and non-market synergies), which broadens synergy beyond internal consolidation into external cooperative environments. A skeptical reading (see [[contrarian-ma-value-source]]) is that "ecosystem synergies" partly relabel long-studied network effects and platform expansion.
