Builds software factories for large enterprises, with its own coding agent and a hosted runtime for agent apps.

## Overview

Diffusion builds software factories for large enterprises through three offers. Factory Building is a hands-on service where customer operators work with Diffusion in Silicon Valley to build their factory and learn to run it. Diffusion Agent is its own large-scale coding agent, which hands implementation to frontier coding systems from Anthropic, OpenAI and Google. Diffusion Cloud is a hosted runtime for the resulting agent apps.

Every agent change must pass a critic, a validator, a digital twin test environment and runtime rules, and failures go back to the last known-good state. Diffusion was founded by Justin McCarthy, previously co-founder and CTO of StrongDM.

**Who it is for:** Large enterprises.
