RWX raises $12M Series A to fix AI's code validation bottleneck
RWX, a dev cloud platform built for AI-driven software engineering, has raised a $12 million Series A led by Hyde Park Venture Partners. Existing investor Quiet Capital joined, alongside The O.H.I.O. Fund, R1 Capital, DV Trading, and angel investors including Bryan Johnson and Jenkins creator Kohsuke Kawaguchi.
RWX — named after the read, write, and execute permissions in file systems — runs a cloud where engineers and AI coding agents build, test, and validate software. The Columbus, Ohio company will use the funding to expand its team and accelerate development of the platform.
AI agents now write code faster than any human can. But the systems meant to check that code — CI pipelines, test suites, deployment infrastructure — were designed for human-paced work, and RWX argues they have become the biggest bottleneck.
"The limiting factor in software engineering is no longer writing code. It's validating it," said chief executive officer and co-founder Dan Manges. He previously co-founded Root and served as founding chief technology officer of Braintree before its acquisition by PayPal.
Engineering teams at Honeycomb, Verkada, nCino, and Coalesce. Honeycomb staff engineer Dean Strelau said in a case study that "our CI system couldn't keep pace with AI-assisted development," crediting RWX's caching for keeping validation fast as build volume grew.
At $12 million, RWX's round sits below the median for its category, a modest bet on a wager that AI-native development needs an infrastructure stack rebuilt from scratch rather than retrofitted. Investors are backing the founders' track record as much as the thesis — a pattern as coding agents reshape where engineering time, and money, gets spent.
