Biz - Four Deadly Sins of Platforms
Cusumano, Gawer, and Yoffie studied dozens of platform failures and identified four recurring strategic mistakes that kill platforms. These aren't edge cases — they're systematic errors that even well-funded, well-led companies make repeatedly. The framework is valuable because it gives you a checklist of failure modes to actively guard against. Most platform failures can be traced to one or more of these four sins.

How It Works
The four deadly sins:
- Mispricing — Getting the subsidize-one-side economics wrong. Platforms typically need to subsidize one side to bootstrap the other (free for consumers, charge businesses). Mispricing means: charging the wrong side, charging too much too early (killing adoption), subsidizing too aggressively (burning cash without building real engagement), or failing to adjust pricing as the platform matures. The "penny to cross the bridge" problem — you need to figure out which side is more price-sensitive and subsidize them.
- Mistrust — Failing to build ecosystem confidence. Developers won't build on your platform if you might compete with them (Apple rejecting apps that compete with built-in features). Partners won't join if governance is unpredictable (Amazon launching private-label products that compete with marketplace sellers). Mistrust kills ecosystem growth because complementors need confidence that the platform won't exploit them. The "embrace, extend, extinguish" reputation destroyed trust in Microsoft's platform for a decade.
- Mistiming — Launching too early or too late. Too early: the market isn't ready, complementors haven't emerged, infrastructure doesn't exist (Apple Newton, Google Glass v1). Too late: incumbent already has network effects locked in (Google+ launching against Facebook, Windows Phone against iOS/Android). The timing window for platform launches is narrow, and being early is often worse than being late — you educate the market but the fast follower captures it.
- Hubris — Overestimating platform power and over-extracting from the ecosystem. High take rates that drive participants to alternatives (App Store's 30% driving Epic Games lawsuit and sideloading pressure). Aggressive terms that alienate developers. Assuming users can't leave when switching costs are lower than you think. Google+ failed despite Google's massive scale and data because users were already well-served by Facebook — Google assumed its distribution advantage would overcome established network effects.
