Factory triples valuation to $5 billion with $200 million raise

Factory, the San Francisco startup building AI agents for enterprise software engineering, said on September 15, 2026 that it has raised $200 million at a $5 billion valuation, more than tripling the $1.5 billion mark it reached in April. The round lifts total funding above $400 million and underscores investor demand for tools that move companies from one-off coding agents toward governed, company-wide software factories.

Investors crowd into agentic engineering

According to Factory’s announcement, co-authored by founders Matan Grinberg and Eno Reyes, the financing came from Blackstone, Khosla Ventures, Sequoia Capital, Insight Partners, Evantic Capital, Sound Ventures, NEA, Mantis VC, and Clearlake. Reuters reported that the company previously raised $150 million at a $1.5 billion valuation in April, so the new price represents a sharp step-up in under six months.

Grinberg, co-founder and CEO, told Reuters that large enterprises are shifting “from individual coding agents to software factories that serve as the core foundation from which an entire software company operates.” Factory says the new capital will accelerate research, product, and global go-to-market spending.

What Factory sells to big companies

Founded in 2023, Factory positions itself as a single system for the full software development lifecycle rather than a stack of disconnected agents. The company says customers can control how the system learns, which models it uses, and where it runs, including cloud, on-premises, and air-gapped deployments aimed at regulated and public-sector buyers.

Factory claims hundreds of thousands of developers use the platform and names Nvidia, Blackstone, Royal Bank of Canada, Palo Alto Networks, Adobe, and T-Mobile among enterprises building what it calls self-improving software factories. In April it announced Factory 2.0, framing a move from individual coding agents into broader “software factories,” plus Factory Router for task-level model routing that the company says cut token spend by more than 60% while keeping frontier performance. It also highlighted Agent Effectiveness metrics so buyers can see measurable return on AI spend.

Why the raise lands now

AI-assisted coding is among the most widely adopted uses of generative AI, Reuters noted, drawing heavy investment as companies try to ship software faster. Factory competes with platforms such as Cognition and Cursor. Reuters said Cognition raised $2 billion at a $48 billion valuation earlier in September, a reminder that coding-agent valuations have moved quickly even as some industry executives urge caution about the pace of AI progress.

The raise also fits a wider corporate push to reshape work around AI productivity, which Reuters linked to companies such as Coinbase and Block. Factory’s pitch is that enterprises want not only faster code generation but a controllable, measurable system they can trust across the lifecycle.

How the $200 million translates into product depth, enterprise wins, and rivalry with better-funded peers remains the next clear test.
