MCP Startup Runlayer Sues Rippling Over Alleged AI Product Copying: What Happened?

MCP Startup Runlayer Sues Rippling Over Alleged AI Product Copying

The AI infrastructure industry is witnessing another major legal battle. Runlayer, a startup specializing in secure Model Context Protocol (MCP) gateways, has filed a lawsuit against HR software giant Rippling, alleging that the company copied its technology after an extended product evaluation.

The case raises important questions about intellectual property, enterprise software trials, and the growing competition in AI infrastructure.

What Is the Dispute Between Runlayer and Rippling?

According to the lawsuit, Runlayer worked closely with Rippling during a lengthy product trial. The startup claims the collaboration lasted nearly a year and involved significant engineering discussions.

As part of the evaluation process, Runlayer shared:

• Product roadmap
• Technical architecture
• Source code
• Engineering insights

Both companies reportedly signed:

• A mutual non-disclosure agreement (NDA)
• A product trial agreement prohibiting Rippling from copying or creating derivative products

Runlayer believed these agreements would protect its intellectual property throughout the evaluation process.

Why Did the Partnership End?

Despite months of collaboration, the companies could not reach a commercial agreement.

According to the complaint, pricing became the main issue, leading Runlayer to end the product trial.

Soon after, Runlayer claims its CEO, Andrew Berman, received a message from someone inside Rippling alleging that the company was building what was described as an almost identical version of Runlayer’s product.

This allegation became the foundation of the lawsuit.

Runlayer’s Allegations

Runlayer argues that Rippling’s newly announced MCP gateway is based on confidential information shared during the product evaluation.

The lawsuit includes claims of:

• Trade secret misappropriation
• Breach of contract
• Unfair competition
• Unauthorized use of proprietary technology

To strengthen its legal position, Runlayer has hired the well-known law firm Sullivan & Cromwell.

While this does not determine the outcome of the case, it signals that the startup intends to aggressively defend its intellectual property.

Rippling Denies the Claims

Rippling has confirmed that it is launching its own Model Context Protocol (MCP) gateway.

However, the company strongly denies copying Runlayer’s technology.

According to a Rippling spokesperson, the company developed its product using only its own proprietary information and believes its solution will compete successfully in the market.

Rippling also criticized the lawsuit, describing it as an attempt to avoid competition rather than a legitimate intellectual property dispute.

As of now, the allegations remain unproven, and the matter will be decided through legal proceedings.

What Is an MCP Gateway?

A Model Context Protocol (MCP) gateway acts as a secure bridge between AI models and external business systems.

It enables AI assistants and autonomous agents to safely access:

• Company databases
• Internal applications
• APIs
• Enterprise software
• Business tools

By managing authentication, permissions, and security, MCP gateways help organizations deploy AI safely while maintaining control over sensitive information.

As enterprise AI adoption accelerates, demand for secure MCP infrastructure continues to grow.

Why This Lawsuit Matters

Beyond the legal dispute, the case highlights a common challenge faced by AI startups.

Enterprise customers often require extensive product evaluations before making purchasing decisions.

These trials typically involve:

• Deep engineering collaboration
• Technical demonstrations
• Product customization
• Access to confidential product details

While these evaluations help customers make informed decisions, they can also expose startups to intellectual property risks if proper safeguards are not maintained.

The Runlayer-Rippling dispute illustrates the delicate balance between winning enterprise clients and protecting proprietary technology.

The Growing Competition in MCP Infrastructure

The MCP ecosystem has expanded rapidly since Anthropic introduced the open-source Model Context Protocol in late 2024.

Today, numerous startups and enterprise software companies are building products around the protocol.

MCP gateways have become essential because they provide:

• Enterprise-grade security
• Access control
• Governance
• Agent management
• Compliance capabilities

Runlayer entered this market in 2025 and has raised $42 million from investors, including Khosla Ventures and Felicis, demonstrating strong confidence in the future of AI infrastructure.

As more companies enter the market, competition is becoming increasingly intense.

Lessons for AI Startups

The lawsuit serves as a reminder that enterprise software sales involve more than just closing deals.

AI startups should consider:

• Using strong confidentiality agreements
• Carefully limiting access to sensitive intellectual property
• Sharing source code only when absolutely necessary
• Clearly defining evaluation boundaries during product trials
• Maintaining documentation throughout enterprise collaborations

Protecting innovation is becoming just as important as building it.

Final Thoughts

The legal battle between Runlayer and Rippling underscores the challenges of competing in one of the fastest-growing segments of artificial intelligence.

Whether the court ultimately rules in favor of Runlayer or Rippling, the case highlights the risks AI startups face when working closely with large enterprise customers.

As AI infrastructure continues to evolve, protecting intellectual property while fostering collaboration will remain a critical challenge for both startups and established technology companies.

Conclusion

The Runlayer-Rippling lawsuit is more than just a legal dispute—it reflects the increasing competition surrounding AI infrastructure and enterprise software. As businesses invest heavily in secure AI integration, startups must balance innovation with strong intellectual property protection. The outcome of this case could influence how future enterprise AI partnerships are structured and how confidential technology is shared during product evaluations.
