OpenAI embraces the 'platform paradox' by selling API access to startups that compete directly with its own apps like ChatGPT. The strategy is to foster a broad ecosystem, believing that enabling competitors is necessary to avoid losing the platform race entirely.

To overcome the cold start problem in a network effects business, especially in a conservative industry like finance, a powerful strategy is to create a coalition or consortium model. By giving early adopters ownership and governance rights, you align incentives, build trust, and transform would-be competitors into enthusiastic evangelists for the new network.

Blockchain's disruption will not impact all of finance equally. Trading firms are safe because market making is a fundamental need. However, intermediaries like banks, exchanges, and custodians face an existential threat as their core function—managing ledgers and access—is directly replaced by blockchain's "private key and a ledger" infrastructure.

The last decade of crypto focused on moving assets like Bitcoin on-chain. The next, more significant mega-trend will be the migration of entire companies and their real-world revenue streams onto blockchains, involving both crypto-native firms and traditional giants like BlackRock and Stripe.

Startups are becoming wary of building on OpenAI's platform due to the significant risk of OpenAI launching competing applications (e.g., Sora for video), rendering their products obsolete. This "platform risk" is pushing developers toward neutral providers like Anthropic or open-source models to protect their businesses.

The crypto community often criticizes platforms like Solana for paying partners like Western Union. However, this "pay-to-play" model is a standard business development strategy used by giants like Amazon (for Alexa) and Facebook to bootstrap their ecosystems and kickstart the flywheel with marquee partners.

OpenAI's partnership with Stripe to enable in-app purchases transforms ChatGPT from an information tool into a transactional platform. This creates a frictionless sales channel for e-commerce brands, directly challenging Google's established search-to-purchase business model.

IBKR's low-cost, tech-first model is strategically counter-positioned against high-touch incumbents like Charles Schwab. Adopting IBKR's model would require competitors to cannibalize their profitable existing business models, creating a powerful competitive moat based on the innovator's dilemma.

Beyond technical features, Ethereum's core value is its "credible neutrality." The protocol doesn't favor any single user, allowing a Nigerian remittance app to have the same infrastructure access as JP Morgan. This fundamental fairness drives its network effect and widespread adoption.
