Anthropic wants you to build on Claude. There’s a catch.

Anthropic is inviting developers to build businesses on its Claude AI model, but its expansion into enterprise software has raised concerns among founders. One such concern was raised by Gerald Zingraf, president and COO of GlacierGrid, who compared Anthropic's strategy to Amazon's private-label business. Zingraf expressed worry that Anthropic could see the third-party integrations customers use most frequently and potentially incorporate those capabilities into Claude itself.

This concern stems from the possibility that Anthropic could gain insight into its third-party integrations and use that information to inform its product development.

The risk is not just hypothetical for some developers. Legal AI startup Spellbook recently experienced this when Anthropic introduced Claude for Legal, a product that competes with Spellbook's services. Spellbook CEO Scott Stevenson described how Anthropic assured him there were no plans to enter the legal software market, only for Anthropic to launch Claude for Legal later.

While Spellbook still uses Claude for contract review, Stevenson highlighted the challenging situation developers face when their products depend on frontier models.

Tech founder and CEO Todd Saunders echoed these concerns, drawing a parallel between Anthropic and Amazon, warning developers that Anthropic could observe application usage and incorporate competing functionality into Claude. Anthropic's privacy policy does acknowledge the company's access to data about customer interactions with third-party apps and services. However, it is unclear whether Anthropic monitors which integrations are most popular when deciding what to build next.

Under Anthropic's commercial terms, customers retain ownership of their inputs and outputs, and Anthropic agrees not to use their content to train its models. However, the company's documentation does not explicitly state how Anthropic uses aggregated integration data. Despite these concerns, Anthropic is still encouraging developers to build on Claude, with the understanding that access to its growing enterprise customer base comes with a tradeoff.

The relationship between developers and Anthropic remains a delicate balance, hinging on how Anthropic decides to expand its offerings in the future.
