Rippling Countersues Runlayer in Patent Dispute Over AI Integration Tech

HR platform Rippling has filed a countersuit against startup Runlayer, accusing it of infringing three of its patents. This move comes in response to a lawsuit filed by Runlayer against Rippling a month earlier, where the startup claimed Rippling breached a contract and stole its product ideas.

The conflict escalated after Rippling tested Runlayer’s product for nearly a year without signing a paid contract. Instead, Rippling developed its own MCP server solution, which it plans to launch as a competing product. MCP is an open standard that enables AI agents to interact with corporate systems and data for autonomous operations.

Runlayer founder Andrew Bergman, who previously co-founded Nanit and Vowel (acquired by Zapier in 2024), argued that Rippling’s lawsuit is an attempt to distract from its own challenges. He stated that Runlayer’s product does not infringe on Rippling’s patents and that the company will vigorously defend its intellectual property. Rippling, in turn, dismissed Runlayer’s claims as hypocritical, emphasizing that the startup itself is violating its patents.

This legal battle highlights the growing risks in relationships between large corporations and startups, especially as AI development accelerates. Corporations are increasingly opting to develop technologies in-house, which could undermine collaboration with innovative young teams.
