# What Is Platform Risk?

> Platform risk is the danger that a startup's business depends too heavily on a third-party platform—app stores, ad networks, or marketplaces—that can change rules, fees, or access without warning.

**Platform risk** is exposure to policy, algorithm, or economic changes controlled by an intermediary platform on which a startup relies for distribution, identity, payments, or demand.

### How it works

A mobile app sold only through iOS inherits App Store review rules, commission structure, and search ranking logic. A DTC brand spending 90% of budget on one social ad network inherits CPM swings and account bans. Marketplace sellers inherit fee hikes and search placement changes.

Diligence maps revenue and acquisition by channel. High concentration triggers questions about direct channels—email lists, SEO, sales teams—and contractual terms with partners. Some risks are structural; mitigation is diversification and faster path to owned data.

### Why it matters

- **Founders:** Board decks should show channel mix trends, not just blended CAC. Sudden policy shifts belong in risk registers.
- **Investors:** Platform-dependent growth can look efficient until it is not. Stress scenarios belong in investment memos.

### Common mistake

Assuming good standing with a platform today guarantees tomorrow. Historical partnership warmth does not bind future product or policy teams at large platforms.

## FAQ

### What is platform risk in simple terms?

It is building on rented land. If Apple, Google, Meta, or Amazon changes policies, your customer acquisition or revenue can drop overnight even if your product still works.

### Why does platform risk matter?

Investors discount businesses with single-channel dependency. Founders mitigate platform risk by owning direct customer relationships, diversified channels, and contractual clarity where possible.
