Runlayer and Rippling have quietly dropped their mutual lawsuits as of Wednesday night — but not before making waves in the enterprise AI world. Neither company settled nor exchanged money (including legal fees), according to court filings reviewed by us. Gone is Runlayer’s lawsuit over Rippling allegedly copying its MCP gateway; gone, too, is Rippling’s countersuit, which accused Runlayer of infringing its patents.

How We Got Here
Runlayer, a startup that emerged from stealth in November 2025 with $42 million in venture funding from firms such as Khosla and Felicis, claims it spent over a year collaborating closely with Rippling. During that time, Rippling tested Runlayer’s MCP gateway under trial conditions, exploring its technology without becoming a paying customer.

At some point, Runlayer alleges it learned via text from a Rippling employee that Rippling was building a nearly identical MCP gateway. That purported clone, it claimed, was destined to compete directly with Runlayer’s product. Consequently, Runlayer sued Rippling for contract violations tied to their joint testing period. Rippling responded with a countersuit, accusing Runlayer of patent infringement—widely interpreted by observers as a move to raise the stakes in litigation costs and pressure Runlayer into backing down.

Products, Markets, Stakes
At issue is the MCP gateway category: middleware that mediates enterprise AI agents’ access to internal software systems. Rather than giving AI tools direct access, these gateways serve as a control layer—enforcing permissions, tracking model usage, and managing observability and auditing functions. Enterprise buyers are increasingly demanding tools that not only enable AI agents but do so under controlled, transparent security regimes.

While Runlayer’s offerings include a full stack of AI agent governance, Rippling’s new MCP gateway adds employee role-based access control, dashboards for usage and token spend, and supports routing to different AI models. In expanding into MCP gateways, Rippling—traditionally known for payroll and benefits—now competes with players like Runlayer, Docker, Amazon Bedrock, Stripe, Ramp, and Databricks.

Why the Lawsuits Fizzled Out
After three weeks of discovery, Runlayer dropped its lawsuit. Rippling followed suit, withdrawing its countersuit. Neither side collected damages or resolved the claims through legal bargaining. What remains is public friction—not settled claims. ([techcrunch.com](https://techcrunch.com/2026/08/20/runlayer-rippling-drop-lawsuits-but-the-brouhaha-is-still-a-cautionary-tale-for-founders/))
No explicit reasoning has been disclosed for ending the litigation, but it appears both parties decided the cost—in reputational risk, legal fees, or otherwise—outweighed any potential gain. The exposure of internal engineering relationships, risks to partnerships, or investor concerns may also have played a role.
This saga underscores a larger point: in today’s fast-moving AI economy, your tester may become your rival, or your partner. Projects can mutate; competitive threats can spring from places you least expect. What starts as collaboration might end as competition overnight. The MCP gateway category is no longer a niche tool—it’s at the heart of customer demands for AI safety and infrastructure.
Founders should take note. Partnerships with enterprises or larger platforms carry risks beyond missed deals—they may expose startup innovations to better-resourced organizations that can decide to build similar products internally. Legal protection matters, but it won’t always save you. Strong IP, clear contracts, and careful navigation of test/triage relationships can help, but even then, the rules are shifting.
