Moving from a strong position in one domain into an adjacent one is the most reliable path to sustainable growth — when the adjacency is genuine.
What Makes an Adjacency Genuine
Adjacent domain entry — the expansion from a position of strength in one domain into a neighbouring one — is one of the most reliably successful growth strategies available to organisations and professionals with established positions. The established position provides the credibility, the relationships, and the institutional familiarity that new entrants in the adjacent domain lack. The adjacency provides the overlap in capability, audience, and context that makes the entry credible rather than arbitrary.
The key variable is whether the adjacency is genuine. A genuine adjacency is one where the capability and credibility built in the core domain provide a real starting advantage in the adjacent one — where the audiences overlap, the capabilities transfer, and the trust built in the core domain is relevant to the adjacent one. A nominal adjacency is one that appears proximate on the surface but where the competitive dynamics, audience needs, and required capabilities are sufficiently different that entry must be built from essentially zero, regardless of the apparent similarities.
How to Test the Adjacency
Testing whether an apparent adjacency is genuine requires assessing three dimensions. First, audience transfer: do the audiences in the adjacent domain know and trust the entering party from the core domain, and does that knowledge and trust create a meaningful starting advantage? Second, capability transfer: do the capabilities developed in the core domain provide a genuine head start in the adjacent domain, or must they be substantially rebuilt for the adjacent domain's requirements? Third, competitor positioning: does the adjacent domain's competitive landscape include incumbents who would see the entry as a territorial threat and respond with the kind of resource commitment that could eliminate the entering party's apparent advantage before it can be converted into a durable position?
Sequencing the Entry
Adjacent domain entry is most reliably executed when the entry begins at the boundary of the core domain — at the point of maximum overlap — and expands inward from that boundary as the entering party builds credibility and relationships in the adjacent domain. Entry that begins at the centre of the adjacent domain rather than at its boundary requires competing without the advantage that adjacency provides, which eliminates the strategic rationale for using the adjacent domain entry approach rather than direct market entry.
The adjacent domain is the one where your existing position gives you a starting advantage rather than a handicap. The test is not whether the domains are similar — it is whether your strength in one translates into a credible starting position in the other.
