What happens when growth depends on a channel you do not control?

What history suggests

• Companies that replaced a broken acquisition channel generally rebuilt demand through a different mechanism rather than restoring the old one.
• An intermediary becomes infrastructure when other participants build their own operations around it, which is a different position from simply handling volume.
• Owning the transaction does not guarantee owning the decision. The party the customer treats as the point of contact tends to accumulate the relationship.
• Contractual restrictions on intermediaries appear weaker than structural ones, such as controlling the data, the servicing moment, or the ongoing reason for contact.
• When the customer can see what the intermediary earns, the intermediary's position depends more on visible usefulness than on placement.

What changes the answer

Conditions and contexts where the evidence differs.

• An intermediary that only moves volume is in a different position from one others have built their operations around. The second is much harder to displace or replace.
• Where the customer can see the intermediary's economics, position rests on visible usefulness rather than on placement, which changes what a defense has to look like.
• Structural holds, such as data, the servicing moment, and a recurring reason for contact, behave differently from contract terms, and a company may hold one without the other.

What to look at in your business

Practical application, not historical finding.

• What share of new customers arrives through a single channel?
• Who does the customer contact first when something goes wrong?
• Which party holds the usage, account, or servicing data?
• If the channel changed its terms tomorrow, how long would demand persist?
• What second demand mechanism has been tested, and at what volume?
• Can the company state plainly what each layer in the chain contributes?
