Port has raised $100 million to challenge Spotify’s open source Backstage with a managed platform that solves the growing chaos around enterprise AI agent orchestration.
Port has secured $100 million in a Series C round led by General Atlantic, with participation from Accel, Bessemer Venture Partners, and Team8, pushing the company to an $800 million valuation. The raise brings Port’s total funding to $158 million, following its $35 million Series B in May.
Founded in 2022, the Israeli startup has built a proprietary enterprise developer portal and AI agent orchestration platform, positioning itself as a direct challenger to Spotify’s Backstage, the widely adopted open source framework used to build internal developer portals. Although Backstage is popular, its build-it-yourself nature demands significant engineering effort, leaving enterprises searching for managed alternatives.
Port has already attracted major customers including GitHub, British Telecom, and LG, reinforcing its relevance in a market increasingly shaped by AI automation. Coding was among the earliest areas transformed by LLMs, and developers are now rapidly building agents to handle tasks that go far beyond code generation.
Port argues that this shift has created a “Wild West” inside enterprises, where agents are hard to track, inconsistent to share, and lack governance and guardrails. As CEO Zohar Einy explains, “Developers want to take AI beyond just coding. They want it to resolve incidents, resolve security issues. They want it to take care of the release management.” Without oversight, he adds, “it creates chaos.”
Port’s orchestration layer tackles this through performance measurement, human-in-the-loop controls, and a “context lake” that defines data sources, memory, and guardrails — “what agents ‘need to know’ to do their job safely and correctly,” Einy says. The platform also provides cataloguing tools, agent creation features, pre-built agents, and an interface for governance — covering, as Einy notes, “all the 90%” of engineering work that is not writing code.
With competition from LangChain, UiPath, Cortex, and several Big Tech efforts, Port enters a crowded field, but its enterprise-ready alternative to open source Backstage gives it a sharpened edge in the fast-moving agentic management landscape.
