Transaction friction between parties who cannot efficiently find or evaluate each other creates a fee opportunity for the intermediary who reduces that friction without owning what is exchanged.
How reducing transaction friction between parties creates a business where value comes from connection rather than production.
Introduction
Many economic transactions would not occur efficiently — or at all — without someone in the middle. A real estate broker connects buyers and sellers of property. A stockbroker executes trades between investors and markets. An insurance broker matches clients with appropriate policies from multiple insurers. In each case, the intermediary does not own what is being exchanged. Their value comes from reducing the friction that would otherwise prevent or delay the transaction.
The structural logic is straightforward: where friction exists between parties who would benefit from transacting, an intermediary who reduces that friction can capture a portion of the value they enable. The friction can be informational (parties cannot find each other), evaluative (parties cannot assess quality or terms), procedural (transaction mechanics are complex), or trust-based (parties need a credible third party to ensure fair dealing).
Understanding intermediation structurally means examining what creates the friction, how the intermediary reduces it, and what determines whether the intermediary's position is durable or vulnerable to disintermediation.
Core Business Model
Revenue comes from fees charged for facilitating transactions. Commission structures charge a percentage of the transaction value, aligning the intermediary's revenue with the size and frequency of transactions. Flat fees charge a fixed amount per transaction regardless of value. Retainer or subscription models charge ongoing access fees. Some intermediaries earn spreads, the difference between the price at which they facilitate on each side of the transaction, rather than explicit fees.
The cost structure is typically labor-intensive. Intermediation often requires expertise, relationship maintenance, and individualized service. Personnel costs for brokers, agents, and advisors are usually the dominant expense. Technology costs for matching platforms, transaction processing, and information systems supplement labor. The cost structure is more variable than fixed, scaling roughly with transaction volume.
The intermediary's value proposition must exceed the cost of the alternative: finding the counterparty directly, evaluating the opportunity independently, or navigating the transaction mechanics without assistance. When the intermediary's fee exceeds the cost the parties would incur by transacting directly, the intermediary's position is structurally vulnerable. When the friction reduction is genuine and the fee is proportionate, the position is structurally supported.
Trust and reputation are structural assets for intermediaries. Both parties in a transaction rely on the intermediary's integrity, competence, and impartiality. An intermediary with a strong reputation attracts both sides of transactions, creating a network effect where the presence of quality participants on each side attracts more quality participants. Reputation takes time to build and can be destroyed quickly, making it both a barrier to entry and a source of vulnerability.
