RWX has raised a $12 million Series A led by Hyde Park Venture Partners. Quiet Capital, The O.H.I.O. Fund, R1 Capital and DV joined, along with angel investors Bryan Johnson and Kohsuke Kawaguchi. The company has now raised $19 million since it started.

Based in Columbus, Ohio, RWX runs a cloud platform built for AI driven software engineering. The name comes from read, write and execute, the permission bits familiar to anyone who has worked in a computer file system.

The company is aimed squarely at a bottleneck that has appeared as coding agents have become more capable. Agents can now write a great deal of code quickly. Building, testing and validating all of it at the same speed is the harder half, and that is where RWX puts its attention.

The founding team has done this before. Chief executive Dan Manges cofounded Root, now listed on the Nasdaq, and served as founding chief technology officer at Braintree before PayPal acquired it. Tommy Graves is chief technology officer.

RWX plans to use the capital to grow the team and speed up development of the dev cloud platform.
