Pulumi

Infrastructure-as-code platform that launched Pulumi Neo, a purpose-built AI agent for automating cloud infrastructure tasks including provisioning, security, and compliance at enterprise scale. CEO Joe Duffy pulled a third of his 130-person workforce to build Neo; launched 2025; uses general-purpose programming languages for IaC; strong Kubernetes and multi-cloud support.

Pulumi Neo represents the first serious AI agent purpose-built for platform engineering, pulling IaC into the agent-driven workflow and redefining how infrastructure teams operate.

Founder backgrounds

Eric Rudder

Co-Founder & Executive Chairman

A 23-year Microsoft veteran, Rudder rose to Executive Vice President of Advanced Strategy, overseeing Microsoft Research, Trustworthy Computing, and company-wide technical strategy. He previously served as Microsoft's CTO and as a technical assistant to Bill Gates. Earlier roles included leading the Developer and Platform Evangelism division and the Servers & Tools group. Rudder holds an undergraduate degree from Brown University (1988). His deep experience across developer tooling, platform strategy, and enterprise infrastructure directly informed the founding of Pulumi in 2017 alongside Joe Duffy and Luke Hoban.

Joe Duffy

Co-Founder & CEO

Spent roughly 15 years at Microsoft across the Developer Division, Operating Systems Group, and Microsoft Research, ultimately serving as Partner Director of Technical Strategy for developer tools. In that role, he managed the teams shipping C#, C++, Visual Basic, and F#, initiated the effort to take .NET open source and cross-platform, and created teams for several distributed programming platforms. Earlier, he was a development manager and language architect on Midori, Microsoft's research operating system built around cloud-centric, concurrent, and safe-by-default design principles — experience that directly informed Pulumi's thesis that infrastructure should be programmable with general-purpose languages rather than DSLs or YAML. He founded Pulumi in 2017 and has served as its CEO since.

AI bull / bear

Bull case

Pulumi Neo is the earliest and most credible attempt to fuse AI agents with infrastructure-as-code at enterprise scale, and Pulumi's architectural DNA gives it a genuine head start. Because Pulumi uses general-purpose languages like TypeScript, Python, and Go rather than a domain-specific DSL, AI models—already fluent in these languages—can generate, reason about, and remediate infrastructure code far more effectively than they can with HCL or YAML-based tools. CEO Joe Duffy's decision to assign roughly 43 of 130 employees to Neo signals a company-level commitment that competitors have yet to match. The platform's multi-cloud and Kubernetes depth positions Neo to address the full lifecycle—provisioning, security, compliance, and Day 2 operations—in heterogeneous environments that enterprises actually run. With $99 million in total funding and Madrona's backing, Pulumi has the runway to iterate fast. If agent-driven infrastructure becomes the default within platform engineering teams, Pulumi has defined the category before anyone else shipped.

Bear case

Pulumi has spent seven years and $99 million building an elegant IaC alternative that remains a distant second to the Terraform/OpenTofu ecosystem in market share, and Neo risks repeating that pattern in a higher-stakes domain. Enterprises are cautious about letting AI agents autonomously provision, configure, or remediate production infrastructure—a single hallucinated IAM policy or misconfigured network rule can be a security incident. The incumbents have structural advantages: HashiCorp's enterprise relationships are deep, and the major cloud providers are embedding AI assistants directly into their consoles, where most infrastructure work still starts. Meanwhile, the $41 million Series C led by Madrona closed in October 2023; without a follow-on round visible, the burn rate on a 130-person team that has been redirected toward an unproven AI product raises questions. If Neo's enterprise adoption is slower than the CEO's bet demands, Pulumi has diverted resources from its core platform with limited room to recover.

Pulumi Neo
Pulumi Neo is the industry's first purpose-built AI agent for cloud infrastructure automation. Unlike generic AI coding assistants, Neo deeply understands cloud environments, infrastructure dependencies, secrets management, and platform engineering workflows. It can provision, govern, and optimize cloud infrastructure end-to-end — from generating infrastructure code to debugging deployments — all while respecting enterprise policy controls, requiring appropriate approvals, and working within existing Pulumi governance frameworks.
Pulumi Infrastructure as Code (IaC)
Pulumi's open-source infrastructure as code platform enables developers and platform engineers to define, deploy, and manage cloud infrastructure using familiar programming languages like TypeScript, Python, Go, .NET, Java, and YAML instead of domain-specific languages. It supports AWS, Azure, Google Cloud, Kubernetes, and thousands of providers, allowing teams to write unit tests for infrastructure, use standard CI/CD pipelines, and collaborate through code reviews — bridging the gap between application development and infrastructure operations.
Pulumi ESC (Environments, Secrets, and Configuration)
Pulumi ESC is a secrets and configuration management product that centralizes environment variables, secrets, and configuration across teams and clouds. It provides dynamic secret resolution, role-based access control, audit logging, and integration with major secret stores like AWS Secrets Manager, Azure Key Vault, and HashiCorp Vault. ESC helps platform teams enforce consistent configuration management while giving developers self-service access to the secrets and settings they need.
Pulumi CrossGuard (Policy as Code)
Pulumi CrossGuard is a policy-as-code framework that enables platform teams to define and enforce compliance, security, and governance rules using real programming languages. Teams write policies (e.g., encryption must be enabled, specific instance types only) that are enforced during every infrastructure deployment. CrossGuard integrates into CI/CD pipelines and provides guardrails without slowing developers down, ensuring that all cloud resources meet organizational standards before they are provisioned.

Abstract
Language-Neutral Package Schema For A Desired State Configuration System
US12504959
Abstract A desired state configuration system receives a package and a corresponding language-independent schema describing the package and its units. Using the schema, the desired state configuration system can generate wrapper code for each of the programming language supported by the desired state configuration system, the wrapper code simplifying calling of the package and its units from within application code written in those supported programming languages. The code of the package, when called, causes a change in the configuration of a target environment, such as a cloud computing environment.
