Port has closed a $100 million Series C funding round, valuing the company at $800 million. The round was led by General Atlantic, with participation from Accel, Bessemer Venture Partners, and Team8, bringing Port’s total funding to $158 million. The funding supports Port’s mission to move the software industry from manual engineering to autonomous engineering through its Agentic Engineering Platform.
A New Vision for Software Development
Port has grown into a leader in the commercial Internal Developer Portal (IDP) market, serving hundreds of customers globally. IDPs started with a clear promise: give engineers one place to understand their software, tools, infrastructure, ownership, and standards, and to ship faster. That “system of record and system of action” foundation is now the launchpad for Port’s broader shift toward AI-led engineering.
Introducing the Agentic Engineering Platform
Port is building the Agentic Engineering Platform (AEP) as a new layer on top of its existing offering. While AI coding assistants have improved how developers write code, Port is targeting the next phase: moving from AI-assisted to AI-led engineering with humans in the loop. The AEP is designed to bring AI across the entire software development life cycle, not just code creation.
The AEP gives AI agents real responsibility across day-to-day SDLC workflows, including handling tickets from coding through production, self-healing incidents, fixing vulnerabilities, and keeping engineering standards healthy. The goal is to run engineering processes end-to-end and unlock speed and efficiency that teams could not reach through manual processes or coding assistants alone.
Maintaining Human Control and Oversight
Port emphasizes that humans remain fully in control. The company is building a human-to-agent collaboration experience so teams can review, approve, and guide agent decisions at critical points, supporting safer adoption and change management.
Under the hood, the AEP connects to an organization’s tech stack to give agents the context they need. It includes guardrails for safe and consistent actions, workflow orchestration across the SDLC, and a “context lake,” described as a single endpoint for agents to consume high-quality data and tools. Port also highlights visibility into how velocity, quality, throughput, and ROI change over time.
Fueling Future Growth and Innovation
Port says the Series C will accelerate the path it is already on, expanding agentic workflows to every stage of the SDLC and making them accessible across technical stakeholders, including developers, SREs, platform teams, and security, compliance, and operations.
The round positions Port around a broader industry shift toward autonomous engineering. As AI coding assistants become standard, Port is betting that agentic engineering platforms will be the next major layer that reshapes how modern software is built, operated, and maintained.
