AI Startup Runlayer Sues Rippling, Alleging Code Theft During Trial

AI Startup Runlayer Sues Rippling, Alleging Code Theft During Trial

A legal battle is brewing in the AI infrastructure space. Runlayer, a startup that develops a secure model context protocol (MCP) gateway, has filed a lawsuit against human resources software giant Rippling. The startup accuses Rippling of stealing trade secrets, engaging in unfair competition, and breaching contracts during a product trial period.

The case is being handled by the prestigious law firm Sullivan & Cromwell, underscoring the seriousness of the allegations. It also shines a light on the trust and security challenges that arise when selling AI infrastructure to enterprise customers with in-house development capabilities.

A Year-Long Trial Turns Sour

According to the complaint, Rippling engaged in intensive engineering collaboration and product trials with Runlayer for nearly a year. During that time, Runlayer shared its product roadmap and even source code under a confidentiality agreement. But after the trial was terminated due to disagreements over pricing, insiders at Rippling allegedly leaked that the company was developing a clone product that replicates Runlayer's offering.

Rippling has confirmed that it is launching an in-house MCP gateway but strongly denies the allegations of infringement. The company claims the product was independently developed using proprietary technology.

The MCP Gateway Landscape

Since Anthropic open-sourced the MCP protocol at the end of 2024, MCP gateways have become essential infrastructure for securely connecting AI agents to external data. Runlayer's recent lawsuit, which has raised $42 million in funding from investors like Khosla Ventures, highlights the industry risk of technology imitation during deep trials in the enterprise AI tools market.

Key Points

  • Runlayer, an AI startup, has sued HR giant Rippling for allegedly stealing trade secrets and cloning its MCP gateway product during a year-long trial.
  • The lawsuit, handled by Sullivan & Cromwell, claims Rippling used the trial period to copy Runlayer's technology after pricing disagreements ended the partnership.
  • Rippling denies the allegations, stating its in-house MCP gateway was independently developed.
  • The case underscores the risks startups face when sharing sensitive technology with enterprise customers that have their own development teams.
