Runlayer, Rippling drop lawsuits. But the brouhaha is still a cautionary tale for founders.

On Wednesday night, Runlayer and Rippling withdrew their lawsuits against each other, with no settlement, payment, or fee exchange recorded in the filings. Rippling responded by immediately publishing its MCP gateway, the technology at the center of the dispute and a direct competitor to Runlayer’s offering.

Runlayer, founded in November 2025 by serial entrepreneur Andrew Berman and backed by $42 M from Khosla Ventures and Felicis, had let Rippling test its MCP gateway for over a year. After the tests ended without a purchase agreement, a Rippling employee reportedly told Berman that the company was building its own version, which Runlayer alleged copied its product. Runlayer sued for breach of test‑phase contracts; Rippling countered with patent infringement claims, which Runlayer viewed as a pressure tactic.

• MCP gateway mediates AI agent calls to internal systems, enforcing role‑based access, logging, and usage tracking without exposing raw credentials.
• No financial settlement or licensing change occurred; the companies simply ceased litigation.
• The case highlights how pre‑customer collaborations can evolve into competitive threats when IP boundaries are unclear.

Why this matters

From a founder’s perspective, the episode underscores the need for precise, written terms when sharing proprietary technology with potential partners, especially in AI‑enabled infrastructure where functional similarities can be quickly replicated. It also shows that litigation can be used strategically to raise costs even when no monetary outcome is pursued, making early‑stage risk assessment essential.
