Port Raises $100M Series C to Power Agentic Engineering Platform

General Atlantic leads round valuing company at $800M as Port tackles the 90% of developer work AI hasn’t touched

Port today announced $100 million in Series C funding led by General Atlantic with participation from Accel, Bessemer Venture Partners and Team8. The round values Port at $800 million and brings total funding raised to date to $158 million, less than a year after the company’s Series B. The investment will enable Port to transform the software industry from manual to autonomous engineering through its Agentic Engineering Platform (AEP), powering hundreds of customers worldwide including GitHub, British Telecom, Visa, Sonar, StubHub, Serko, and Nando’s. The company has experienced significant customer growth and a 300% revenue increase in the past year.

While AI coding assistants have revolutionized how developers write software, a critical gap remains: according to Gartner, only 10% of a developer’s day is spent writing new code. The remaining 90% – bug fixing, refactoring, design, planning, research, and operational tasks – remains manual and fragmented. For companies investing billions in AI tools and engineering talent, this means their most expensive resources remain trapped in operational overhead rather than innovation.

Port’s AEP addresses this challenge by enabling AI agents to handle operational responsibilities across the entire software lifecycle. Agents process tickets from coding to production, self-heal incidents, remediate vulnerabilities, and maintain compliance standards – unlocking unprecedented velocity while keeping humans in control. The platform connects to the entire tech stack to provide agents with necessary context, implements guardrails to ensure safe and consistent actions, and orchestrates workflows through a unified engine.

The human-to-agent collaboration experience makes this shift practical. Teams review agent decisions through approval workflows, set confidence thresholds for autonomous actions, and guide agents through complex scenarios. Engineers can delegate entire workflows or specific tasks, monitor agent performance in real-time, and intervene when needed. This governance layer ensures organizations can undergo the change management required to fully adopt AI while maintaining trust and control.

“The big question in our industry is what engineering looks like in an AI world,” said Zohar Einy, Founder and CEO of Port. “Our view is simple: humans and agents will run the Software Development Life Cycle (SDLC) together. Agents take on the operational load, humans stay in control, and organizations gain a level of velocity we’ve never had before. That’s the future we’re building with Port.”

The AEP represents the natural evolution of Internal Developer Portals (IDPs). Founded by Zohar Einy and Yonatan Boguslavski, Port advanced the commercial IDP market, creating unified views of software, tools and infrastructure. As engineering teams adopt AI agents and automated workflows, the same visibility and standardization that IDPs provide have become the foundation for AI-driven engineering. Port now leads this transition, transforming from a developer portal into the control plane for autonomous engineering.

“Port’s platform gives us a unified, standards-driven view of our entire engineering landscape. As they move into agentic engineering, we see a world where that intelligence doesn’t just inform — it acts. That’s the next frontier in developer experience,” said Meirav Feiler, VP Engineering, GitHub.

Alex Crisses, Managing Director and Global Head of New Investment Sourcing at General Atlantic, said: “Port’s innovative architecture delivers the governance and orchestration capabilities needed to manage environments where AI agents and human developers operate side by side. We believe Port is well-positioned to capture this significant opportunity.”

By bringing agentic workflows to every stage of the SDLC and making them accessible to all technical stakeholders – developers, SREs, platform teams, security, compliance, and operations – Port enables organizations to achieve the exponential productivity gains that have remained elusive despite decades of tooling investments. Today’s funding further positions Port to define the future of engineering work as the company advances the human-to-agent collaboration experience and reinvigorates a critical gap in engineering workflows – empowering organizations to unlock new levels of productivity.
