Port announced a $100 million Series C funding round led by General Atlantic, with participation from Accel, Bessemer Venture Partners and Team8. The investment values the company at $800 million and brings its total funding to $158 million, less than a year after its Series B.
The new capital will accelerate Port’s push to transform software development from manual work to autonomous engineering through its Agentic Engineering Platform, or AEP. The platform already supports hundreds of customers worldwide, including GitHub, British Telecom, Visa, Sonar, StubHub, Serko and Nando’s. Port reports 300 percent revenue growth over the past year.
AI coding assistants have reshaped how engineers write code, but they address only a fraction of the work. Gartner estimates just 10 percent of a developer’s day is spent writing new code. The remaining 90 percent is consumed by debugging, refactoring, design, planning, research and operational tasks. For companies investing heavily in AI tools and engineering talent, this means their most expensive resources are still absorbed by manual overhead rather than innovation.
Port’s AEP aims to close that gap. The platform enables AI agents to take on operational responsibilities across the entire software lifecycle. Agents can process tickets from development through production, self-heal incidents, remediate vulnerabilities and maintain compliance—boosting velocity while keeping engineers in control. The system connects to the full technology stack to provide agents with the context they need, offers guardrails to ensure safe and consistent actions and orchestrates work through a unified engine.
AEP is designed around human-to-agent collaboration. Teams can review agent actions, set confidence thresholds for autonomous operations and guide agents through complex scenarios. Engineers can delegate entire workflows or specific tasks, monitor agents in real time and intervene when necessary. This governance layer enables organizations to embrace AI agents while maintaining safety and trust.
“The big question in our industry is what engineering looks like in an AI world,” said Zohar Einy, Port’s founder and CEO. “Our view is simple: humans and agents will run the Software Development Life Cycle 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.”
Port’s AEP represents the evolution of Internal Developer Portals. After advancing the commercial IDP market with unified views of software, tools and infrastructure, the company is now extending those capabilities into autonomous engineering. As AI agents and automated workflows proliferate, the visibility and standardization IDPs provide have become the foundation for agent-driven development. Port now positions itself as the control plane for this new model.
“Port’s platform gives us a unified, standards-driven view of our entire engineering landscape,” said Meirav Feiler, VP of Engineering at GitHub. “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.”
Alex Crisses, Managing Director and Global Head of New Investment Sourcing at General Atlantic, added: “Port’s innovative architecture delivers the governance and orchestration 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 software lifecycle and making them accessible to developers, SREs, platform engineers, security teams and operations leaders, Port aims to deliver the productivity gains that decades of tooling have promised but never fully achieved. With fresh funding and a rapidly expanding customer base, the company plans to continue advancing its human-to-agent collaboration framework and redefine how organizations build and operate software.
