When we led Port’s Series A in September 2023, we backed a simple but powerful conviction: openness and flexibility are the foundations for platform engineering at scale. And Port delivered, fast. In just two years, it became the go-to platform for developer experience and Internal Developer Portals (IDP).
Accel and Bessemer followed through and led Port’s B-Round. Today, General Atlantic is leading Port’s $100M C-Round. In only two years since our initial investment, Port experienced exponential growth, attracted some of the best talent and investors in the world, and most importantly, evolved its platform into something far bigger: agentic engineering – the next operating model for how software gets built, shipped, and run in the AI era.
From Developer Portals to Agentic Engineering
Everything about software development is changing. AI is taking the driver’s seat and already powering most of coding. But new code is only ~20% of developers’ time. The other 80%, includes release management, deployment, quality assurance, troubleshooting incidents, fixing vulnerabilities, assuring compliance — all remaining manual, fragmented, and policy-bound.
That’s where Port’s Agentic Engineering Platform comes in, complementing the AI disruption of software development, led by Cursor, Anthropic, GitHub and others, into the remaining 80% of developers’ work.
Introducing agentic workflows to autonomously solve all of these is proving challenging. It requires policies, approvals, verifications, audit, rollbacks and many more. Port is the solution, giving organizations the control plane where shared context, embedded guardrails, and end-to-end execution live in one place. Not isolated co-pilots but rather controlled automation across the board.
Port is landing it in production with some of the leading enterprises in the world such as GitHub, LG, BT, StubHub, and Serko. Large teams are using Port as the context and policy layer for real changes.
We’re proud to back an exceptional team that read the market inflection early and executed fast;. That agility, paired with enterprise proof, is exactly the pattern we look to double down in backing.
Closing the Gap Between Intent and Safe Execution
Agentic initiatives often stall at the handoff between “what should happen” and “what can safely happen.” To bridge that, Port brings three pillars together:
- A living context graph that maps every system, service, and owner.
- Guardrails that travel with the work, enforcing policy as agents act.
- An execution engine wired into CI/CD, cloud, infrastructure, incidents, and ITSM.
The result? Fewer handoffs, faster cycles, lower failure rates, and compliance that happens in real time, not in retroactive audits.
Why Port Wins
Port wins by composition and context. Teams bring their own models, workflows, and interfaces—Port adapts. Its Blueprints power a living graph of context, while agentic workflows run on top. Humans and agents share the same context, act under policy, and close the loop in one surface.
Governance and velocity finally coexist: the easiest path is now the compliant one.
And through its open community, what works in one enterprise quickly becomes a best practice for the next, compounding Port’s network advantage.
Why now
GenAI has outpaced the platforms meant to harness it. Many organizations have multiple capabilities, without a governed way to scale automation across delivery. Platform engineering gave the industry an operating model. Port turns that model into an execution environment where AI can act with context, policy, audit, and rollback.
Outcomes are first-class. The timing is right because results are finally measurable in the language that matters to engineering leaders: lead time, change failure rate, MTTR, and compliance drift are attached to the workflows that move them, so improvement becomes part of daily engineering.
Founders at the forefront of agentic software engineering
We partnered with founders Zohar Einy (CEO) and Yonatan Boguslavsky (CTO) when “portal” was the beachhead. Their pace, clarity, and community stewardship turned an idea into an operating reality for hundreds of enterprises. The Agentic Engineering Platform is the natural extension of that work, same DNA, bigger ambition.
With this $100M Series C, and our continued support as a major investor, Port is poised to scale what’s already working: educate the market on agentic engineering, implement the platform for the largest enterprises, and help teams move from pilots to pervasive adoption and all the way to fulfilling the full vision of autonomous engineering.
Port is standardizing how agentic delivery is done with a clear reference architecture. Opinionated blueprints cover core workflows, and agent safety is built in with least-privilege access, isolation, policy-aware plans, verification, and automatic rollback.
Port has done what few startups do: anticipate a market inflection, execute with precision, and deliver proof at enterprise scale with exponential growth.
That’s why we led the A, doubled down at the B, and all in again for the C! Learn more about Port >> https://port.io/
