What is Aggregation Theory?
Aggregation Theory, developed by Ben Thompson at Stratechery, explains why the most valuable internet-era companies own the user relationship rather than the underlying supply. In pre-internet markets, distribution was scarce and supply control was the strategic asset. The internet inverted this: distribution became effectively free, and aggregators that owned the demand side gained pricing power over the now-commoditised supply.
The three conditions for aggregation
Thompson identifies three conditions any aggregator must satisfy. (1) Direct relationship with users — the aggregator must own the user-facing experience. (2) Zero marginal cost to serve users — adding the next user costs near-zero. (3) Zero-cost supply acquisition — suppliers join the aggregator with low friction because the aggregator already owns demand. Google (search), Facebook (social), Netflix (video), Amazon (commerce) all satisfy the three conditions.
Aggregation vs. traditional platform strategy
Traditional platforms (Microsoft Windows, Intel) won by controlling underlying supply (operating systems, processors) and forcing partners to integrate around them. Aggregators win by controlling user demand and forcing suppliers to compete for visibility to the aggregator’s audience. Aggregation is structurally more powerful because user demand is increasingly the scarce resource on the internet.
Why incumbents fail against aggregators
Three reasons. (1) Defensive instinct mismatched — incumbents protect supply (newspaper subscriptions, hotel inventory) when aggregators are eroding distribution (news links on Google, hotel bookings on Booking.com). (2) Modular vs. integrated mismatch — incumbents are vertically integrated (hotel chains owning property, sales, customer service); aggregators are user-experience focused with modular supply. (3) User relationship loss — once aggregator owns the user, incumbent suppliers become commoditised inputs.
Counter-aggregation strategies
Three patterns work against aggregators. (1) Direct-to-consumer brand — build user relationship that bypasses aggregators (Allbirds, Glossier, Dollar Shave Club). (2) Vertical integration with quality — make supply differentiated enough that aggregators must feature it (Apple’s hardware-software integration). (3) Regulatory moat — supply categories where aggregation is blocked by regulation (healthcare in some jurisdictions, banking pre-fintech).
Türkiye context
Turkish digital markets exhibit aggregation patterns: Trendyol aggregates retail, Hepsiburada aggregates broader commerce, Yemeksepeti aggregated restaurants, Getir aggregates instant commerce. Each captured user demand and forced suppliers (sellers, restaurants, brands) to compete for visibility. Türk founders building against these aggregators need either D2C brand differentiation, vertical integration with quality, or regulatory-protected niches.
