## About Factory

## Company Overview
- **One-liner**: Factory is an AI research lab building autonomous software development agents ("Droids") to automate and optimize the entire software development lifecycle.
- **Entity Type**: Private (Series C)
- **Headquarters**: San Francisco, California, United States
- **Founded**: 2023
- **Founders**: Matan Grinberg (CEO & Co-Founder), Eno Reyes (CTO & Co-Founder)

## Core Business
- Primary industry/industries: Artificial Intelligence, Software Development, Autonomous Agents
- Target customers: Enterprise engineering organizations (B2B)
- Mission or purpose statement: "Bring Autonomy to Software Engineering"

## Products & Services
- **[Droid]**: An autonomous software development agent that performs real engineering work across IDEs, CLI, and CI/CD environments. Handles refactors, migrations, debugging, incident response, and feature development in large codebases. Operates through a model-agnostic architecture and supports long-running processes, structured planning, and verified outputs such as PRs and deployments.
- **[Factory Router]**: A product that automatically selects the right AI model for each coding task, cutting costs 20-25% while maintaining frontier model performance.

## Market Standing
- **Valuation**: $1.5 billion (as of early 2026, per Series C announcement) [cbinsights.com](https://www.cbinsights.com/company/factory-2)
- **Total Funding**: $220M [cbinsights.com](https://www.cbinsights.com/company/factory-2)
- **Latest Funding Round**: $150M Series C (raised ~2 months ago as of July 2026) [cbinsights.com](https://www.cbinsights.com/company/factory-2)
- **Notable Investors**: Sequoia Capital, Lux Capital, NEA, Abstract, MANTIS Venture Capital, 20VC [cbinsights.com](https://www.cbinsights.com/company/factory-2). Board members include AI veteran Lila Tretikov (NEA Partner) [cbinsights.com](https://www.cbinsights.com/company/factory-2).
- **Notable Customers**: NVIDIA, Morgan Stanley, EY, Palo Alto Networks, RBC, Revolut, Adobe, MongoDB [cbinsights.com](https://www.cbinsights.com/company/factory-2)
- **Notable Advisors**: Ali Ghodsi (CEO & Co-founder, Databricks), Aaron Levie (CEO, Box), Dev Ittycheria (CEO, MongoDB), Nikesh Arora (CEO, Palo Alto Networks), Frank Slootman (Former CEO, Snowflake), Michael Ovitz (Co-founder, CAA) [factory.ai](https://factory.ai/company)
- **Growth Signals**: Rapid enterprise adoption moving beyond experimentation; appointed Marcello Gallo as CRO (formerly CRO at Sigma and Moveworks, senior sales leadership at MongoDB) [cbinsights.com](https://www.cbinsights.com/company/factory-2); appointed Madison Faulkner as Head of Strategy [cbinsights.com](https://www.cbinsights.com/company/factory-2); Headcount growing rapidly (+4% monthly on LinkedIn) [linkedin.com](https://www.linkedin.com/company/factory-hq)

## Competitive Advantages
- **Model-Agnostic Architecture**: Factory's Droids are not tied to a single AI model, allowing them to use the best model for each task and switch as the landscape evolves. The Factory Router product further optimizes cost and performance by intelligently routing tasks.
- **Deep Integration**: Agents work natively within existing developer tools (IDEs, CLI, CI/CD), meaning teams don't need to change their workflows to adopt Factory.
- **Enterprise-First Focus**: The company is building for large-scale engineering operations with production-grade reliability, security, and control, as evidenced by their customer list (NVIDIA, Morgan Stanley, etc.).
- **Top-Tier Talent & Advisory**: The team hails from companies like Nuro, Glean, Applied Intuition, Scale AI, MongoDB, and Sourcegraph, and is advised by some of the most prominent leaders in enterprise software.
- **Strong Backing**: Backed by top-tier venture capital firms (Sequoia, Lux, NEA) with a $1.5B valuation, providing significant resources and credibility.

## Strategic Focus
- **Enterprise Hyper-Growth**: Scaling go-to-market with the appointment of a seasoned CRO to drive adoption among large enterprises.
- **Agent-Native Development**: Championing the shift from AI-assisted coding to fully autonomous agents that own and execute complex engineering tasks.
- **Cost Optimization**: Products like Factory Router demonstrate a focus on making AI-powered development cost-effective at scale.
- **Platform Ownership**: Enabling enterprises to own their "software factory" with a flexible, model-agnostic platform.

## Why Work Here
- **Mission-Driven**: The opportunity to "Build the tool you've always dreamed of using" and shape the next era of software engineering [factory.ai](https://factory.ai/).
- **Talent Density**: The company emphasizes being a "lean and talent-dense team" that values ownership and autonomy [factory.ai](https://factory.ai/).
