An AI software factory is the system that absorbs agent output, not the agent itself

How to Build an AI Software Factory: Agents That Open, Review, and Merge PRs

Firecrawl breaks the AI software factory into five gated stages drawn from published architectures. The core tension is that generation scales with spend but human review does not. Spotify's LLM judge vetoes ~25% of agent sessions; Faire requires two human reviews on agent PRs. Stripe boots pre-warmed devboxes in ~10 seconds and exposes ~500 internal tools over MCP. The post argues you build the gates before the fleet—Spotify shipped Fleetshift in 2023, two years before it had an agent to put in it.

Why it matters: Breaks the AI software factory into five gated stages with concrete numbers from Spotify and Faire — useful and actionable. Score held at 72 because it's a vendor blog with promotional intent, and some content is industry synthesis rather than original research.
