Anthropic S-1: over half of $100,000 customers use platform plus app

Anthropic's S-1, filed with the Securities and Exchange Commission on Monday, frames the company's enterprise traction around a deliberate cross-selling strategy. The filing says more than half of customers spending at least $100,000 annually now use both the Claude platform and a first-party app like Claude Code or Cowork, up from about 30% at the end of last year. Anthropic attributes this to what it calls an integrated approach: advances at any layer -- models, developer platform, or applications -- compound across the other two, accelerating how quickly it can deliver more capable intelligence.

The playbook echoes companies like Amazon and Uber, which expanded from a single offering into broader ecosystems. Anthropic says a business that starts with the API can deploy Claude Code to its engineers and then Cowork to its broader workforce. The filing also notes that the highest-spending 5% of Claude Enterprise customers who used Claude Code spent about 20 times as much per month as the average enterprise user who did not use the coding tool, illustrating why Anthropic is keen to get its applications into accounts that start with the API.

To amplify adoption, Anthropic invests in Applied AI teams that help place Claude inside customers' existing technology stacks, and it recently launched a venture with Blackstone and other private equity firms called Ode with Anthropic to embed forward deployed engineers into businesses. The company also leans on third-party distribution partnerships with AWS, Google Cloud, and Microsoft Azure under a joint go-to-market approach. Still, the filing flags headwinds: those same cloud partners increasingly see Anthropic as a competitor, which could complicate securing compute, and customer concentration remains a risk.
