Platform & Ecosystem

A platform provides the foundation — distribution, payments, identity, developer tools — on which other companies build products, then captures value from the activity that results.

It differs from a marketplace in that the third parties are producers building durable products, not merely sellers listing inventory.

Revenue comes from a share of transactions conducted on the platform, developer or listing fees, advertising within the ecosystem, or infrastructure charges for the services provided.

The economics improve as the ecosystem grows, because acquisition cost is increasingly borne by the third parties rather than the platform.

• Number of active developers or partners building on the platform
• Gross platform volume and take rate
• Share of user value delivered by third parties
• Retention of top ecosystem participants
• Time from developer signup to first live product

A healthy platform shows growing third-party activity, partners building businesses of meaningful size on it, and users who would find the platform materially less useful without the ecosystem.

Take rate should be stable and defensible — frequent increases signal weak underlying value.

• Developer platforms with application marketplaces
• Operating systems with app distribution
• Commerce platforms with merchant ecosystems
• Payment platforms with partner integrations
• Data platforms with partner-built analytics

• What proportion of user value comes from third parties?
• Could the platform raise take rate without losing partners?
• How many partners have built businesses of real scale?
• What stops partners from moving to a competing platform?
• What regulatory exposure does platform position create?
