Companies looking for growth beyond their current market face a choice about how far to move. The distance from what they already do predicts the outcome more reliably than the attractiveness of the destination.
Adjacency means something is being reused
A move is adjacent where it draws on an existing asset: the same customers with a different product, the same product for different customers, or the same operational capability applied elsewhere.
That reuse is the source of any advantage the company has over incumbents who are already there.
Without it, the company is a new entrant with no particular claim to win, competing against firms that have been solving the problem longer.
Changing two variables at once compounds the risk
Selling a new product to existing customers means the customer relationship is known and the product is uncertain.
Selling an existing product to a new customer group means the product works and the route to market is uncertain.
Doing both simultaneously leaves nothing familiar to fall back on when something goes wrong, and something always does.
Assumed capability is the usual failure
Companies frequently overestimate how transferable their strengths are, describing themselves as excellent at operations or customer service in general terms.
Those strengths are usually specific to a context, and a capability that works with one type of buyer, at one price point, does not automatically apply elsewhere.
Testing the assumption before committing is cheap compared with discovering it after the investment, though it is frequently skipped because the strength feels obvious internally.
Attention is the scarce input
New markets consume senior management time disproportionately, because everything requires a decision that has no precedent.
That time is taken from the existing business, which usually still supplies all the profit and rarely benefits from the distraction.
Expansion failures often show up as underperformance in the core rather than in the new venture, and the connection is not always drawn.
Small entries preserve the option to stop
Entering at limited scale produces information about whether the assumptions hold, at a cost the company can absorb if they do not.
Large entries create commitments, including hires and contracts, that make withdrawal expensive and therefore delay the decision to withdraw.
Companies that expand successfully tend to run several small entries and expand the ones that work, rather than choosing one destination and committing fully.
