Factory.ai
Purpose-built agent-native software development platform. $50M Series B (September 2025). Droids for the entire SDLC — feature development, migrations, modernization, code review, testing. Customers include MongoDB, Ernst & Young, Zapier, Bilt Rewards, Bayer. 200% QoQ growth throughout 2025.
Factory.ai is one of the few platforms explicitly designed for agent-native development across the entire software development lifecycle, not just code generation. $50M Series B closed September 2025. Generally available.
Droids
Factory’s core concept is Droids — specialized agents for different SDLC tasks:
- Feature Droids — implements features from specifications
- Migration Droids — modernizes legacy codebases
- Code Review Droids — automated PR review and feedback
- Test Droids — generates and maintains test suites
Each Droid operates from terminal, IDE (VS Code, JetBrains, Vim), Slack, Linear, browser, or API.
Technical Differentiation
- LLM-agnostic: uses models from Anthropic and OpenAI
- Interface-agnostic: same Droid capability regardless of how you invoke it
- AGENTS.md support: standard cross-vendor context file for repo-specific agent instructions
- SWE-bench: 58.75% on Terminal-Bench when announced — #1 at that point
Enterprise Customers
MongoDB, Ernst & Young, Zapier, Bilt Rewards, Clari, Bayer. 200% QoQ growth throughout 2025.
This is significant: enterprise validation at this scale is rare among AI coding tools. Most tools have strong developer adoption but limited enterprise penetration.
Level in the Five-Levels Framework
Factory.ai with its full Droid suite represents Level 3–4 for most teams. The Code Review and Test Droids address the validation layer. With custom external scenario testing, Level 4–5.
Best For
Enterprise engineering organizations that want a managed Droids service across the entire SDLC without building their own agent infrastructure. Teams that need enterprise compliance, support, and auditability alongside agent capability.
