Microsoft's deal with OpenAI includes a powerful exclusivity clause. If a third-party company wants to do a deep, custom integration or model training with OpenAI, that workload must be hosted on Azure, effectively funneling major enterprise AI deals through Microsoft's cloud.

A successful platform strategy focuses on leverage. It provides building blocks that reduce internal effort to launch new products, while delivering a seamless, integrated experience that creates lock-in for customers. This leverage is the platform's core value proposition.

A true platform company prioritizes developer choice over favoring its own products. Nadella emphasizes that failing to support all tools, including competitors, will cause developers to leave the platform. This mindset is key to long-term platform dominance and preventing churn.

Instead of broad partner presentations, ISVs should bring a concrete opportunity to Microsoft sellers. Winning that first deal together creates a lasting impression and makes future co-selling more likely because the solution becomes memorable and trusted.

Microsoft's decision to promote Anthropic models on Azure as aggressively as OpenAI's reflects a core belief from CEO Satya Nadella. He anticipates AI models will become commoditized, making the underlying intelligence interchangeable and the cloud platform the primary point of differentiation and value capture.

Large enterprises don't buy point solutions; they invest in a long-term platform vision. To succeed, build an extensible platform from day one, but lead with a specific, high-value use case as the entry point. This foundational architecture cannot be retrofitted later.

For ISVs looking to co-sell with Microsoft, getting their solution onto the marketplace is the most critical step. Microsoft is actively simplifying the first marketplace transaction for both partners and customers, making it the central and preferred mechanism for driving joint sales motions.

Satya Nadella states that Microsoft's core philosophy for platforms like Azure and GitHub is that they are only successful if the ecosystem partners building on top of them capture more economic value than Microsoft does. This partner-first approach is central to their strategy.

Microsoft CEO Satya Nadella argues that the ultimate measure of a platform's success isn't its own revenue, but the economic value created by its ecosystem. A platform thrives when partners and developers generate multiples of the platform's own revenue, creating a durable competitive advantage and fostering global trust.
