Digital platforms were expected to remove intermediaries. In many markets, they have instead created new intermediaries with different sources of power.
Disintermediation and reintermediation
Disintermediation occurs when a transaction bypasses a traditional intermediary. A producer can sell directly to customers through a digital channel.
Reintermediation occurs when a new intermediary provides valuable services such as discovery, matching, payment, trust, logistics, identity or information standards.
A marketplace is not simply a website listing buyers and sellers. It coordinates two or more participant groups whose value depends partly on one another.
Platform economics
Strong platforms reduce the effort required to find and transact with relevant partners. Network effects can improve usefulness as participation grows, but growth is not automatically profitable.
Platform owners must balance the needs of multiple sides. Excessive fees may drive suppliers away. Poor quality controls may undermine buyer trust. Too many low-value listings can increase search costs rather than reduce them.
Multi-homing, participation on competing platforms, can limit a platform’s ability to retain value.
What creates defensibility
Defensibility may come from trusted transactions, proprietary workflows, integrated services, high-quality data, switching costs or strong participant relationships. The number of registered users is rarely sufficient.
For an industrial marketplace, validated technical specifications, supplier certification, accurate availability and integration into procurement may be more valuable than social engagement features.
Management application
When evaluating a platform strategy, identify each participant group and the job the platform performs for it. Map who creates value, who pays and who bears operating risks.
Measure successful matches, repeat transactions, fulfillment quality, cost per completed transaction and the health of both sides of the market.
Do not assume that removing a middleman removes its underlying function. Someone still has to manage trust, discovery and coordination.
Executive decision lens
Decision to make: Separate platform scale from platform health. Prioritize completed, valuable interactions and contribution margin over registrations or gross merchandise volume alone. Assess participant incentives, take rates, trust mechanisms and the probability of multi-homing before assuming durable network power.
Operations Insider takeaway
Platforms win when they organize transactions better than alternatives. Network effects reinforce a useful system; they do not compensate for an ineffective one.
