Launch early on viral platforms before incumbents arrive—timing beats polish
When new platforms open their APIs or ecosystems, there's a brief window where users are hungry to extend functionality and competition is minimal. Being among the first apps available, even with a clunky product, captures explosive early growth that compounds over time through SEO, network effects, and platform promotion. Early apps benefit from: (1) desperate early adopters willing to tolerate friction, (2) free SEO from being first result for '[platform] + [feature]' searches, (3) platform investment/promotion of ecosystem showcases, (4) learning curve advantage as platform evolves. Wait for perfect product and you'll launch into saturated market with entrenched competitors.
When to use
When a major platform (Slack, Shopify, Notion, etc.) opens an API or app ecosystem. When you see people asking for your functionality on Twitter/forums for that platform. When you already have a product in one format that can be quickly ported to the new platform. When platform is growing virally and users are hungry for extensions.
Don't do this
Waiting to build perfect onboarding before launching on new platform. Missing the window because you're perfecting features. Launching after ecosystem is saturated. Building for mature platforms where 'there's an app for that' is already well-established for your category.
