RWX raises $12 million Series A to tackle AI code validation bottleneck
Generative AI solved the code-creation problem, but legacy CI/CD systems are choking on the output. As autonomous agents take over the developer stack, serial founders Dan Manges and Tommy Graves are scaling the infrastructure needed to validate AI-generated code at machine speed.
Columbus-based developer cloud platform RWX announced a $12 million Series A funding round led by Hyde Park Venture Partners, targeting software engineering’s newest operational bottleneck: code validation in the age of autonomous AI agents.
The capital comes as generative AI tools transform software creation. While autonomous AI coding agents can now produce and modify complex code in minutes, traditional continuous integration (CI) pipelines and test environments—built years ago for human-paced development—have turned validation into the slowest step in the development loop.
Why it matters
The economics of software delivery have inverted. For decades, manually writing code was the primary delay in shipping software. Today, AI agents generate code almost instantly, exposing legacy CI/CD systems as a major drag on productivity.
"When writing code took two hours, a ten-minute CI run was acceptable," said Jared Palmer, former SVP at GitHub. "When an agent writes the same code in five minutes, CI suddenly consumes 67% of the development cycle."
By building an agent-first cloud infrastructure from the ground up, RWX is positioning Central Ohio as an anchor for the next generation of developer tooling.
"The limiting factor in software engineering is no longer writing code," says Dan Manges, co-founder & CEO of RWX "It’s validating it. Every major shift in software development has required new infrastructure, and AI-driven engineering is no different."
By the numbers
- $12M: Total Series A capital raised, led by Chicago-based Hyde Park Venture Partners.
- 67%: Share of a development cycle eaten up by legacy CI when an AI coding agent writes code in 5 minutes versus a human taking 2 hours.
- $800M & ~$6B: Previous exit and IPO valuations scaled by Dan Manges as founding CTO of Braintree (acquired by PayPal for about $800 million) and co-founder of Root Insurance (IPO at roughly a $6 billion market cap).
- 29 seconds: Execution time for an RWX workflow running three Node versions and a Chrome installation—so fast that Anthropic’s Claude agent initially questioned whether the execution had actually run, according to the company.
The tech stack
RWX—named after the standard Unix file system permissions read, write, execute—replaces conventional webhook-driven CI models with an execution architecture engineered specifically for coding agents:
- Decoupled code execution: RWX decouples execution from version-control webhooks. Agents can test code in sandboxes, execute full CI pipelines, and launch preview web apps via CLI without making a single Git commit or push.
- Graph-based runtime & content caching: Built on an OCI-compatible container runtime, the platform uses content-based caching and graph-based task execution to eliminate redundant command re-runs.
- Native agent integration: RWX allows developers to pair coding agents—including Anthropic’s Claude and other leading AI coding assistants—using automated skill-installation commands that migrate builds natively into the dev cloud.
Who’s in
The Series A round brings together prominent institutional software backers, local capital, and major industry figures:
- Institutional investors: Hyde Park Venture Partners (lead), Quiet Capital (existing investor), The O.H.I.O. Fund, R1 Capital, and DV.
- Angel investors: Kohsuke Kawaguchi (creator of Jenkins, the pioneer of CI/CD automation), Bryan Johnson (Don’t Die), and Theo Browne (founder of t3.gg).
- Enterprise adoption: Commercial engineering teams already using RWX include Honeycomb, Verkada, nCino (NASDAQ: NCNO), and Coalesce.
"Building infrastructure for AI-driven engineering... requires years of experience building systems at scale," says Mark Kvamme, Co-founder and CEO of The O.H.I.O. Fund. "Dan and Tommy have done that before at Root, and they’re applying those lessons to RWX."
Between the lines
For the Ohio tech ecosystem, RWX’s milestone highlights the strength of local, serial tech leadership.
Co-founders Dan Manges and Tommy Graves are building developer infrastructure in Columbus that directly competes with—and replaces—legacy tools originating in Silicon Valley.
