More than three years after generative AI first hit the mainstream, AI-assisted coding is still the use case investors can’t stop circling. It’s practical, it’s measurable, and for teams that ship software for a living, it feels like the fastest path from “cool demo” to actual work.
On Wednesday, Factory, a startup building AI agents for enterprise engineering teams, announced it raised $150 million at a $1.5 billion valuation. The funding round was led by Khosla Ventures, with participation from Sequoia Capital, Insight Partners, and Blackstone. Keith Rabois, a managing director at Khosla Ventures, also joined the startup’s board. The press release made it sound like a clean move into the next phase—though, in practice, these rounds always come with pressure to deliver quickly.
Factory isn’t trying to win on raw model access alone. Its stated differentiator is its ability to switch between different foundation models—for example, Claude from Anthropic or the Chinese AI startup DeepSeek. That’s an interesting angle because some competitors are also positioning themselves around multi-model approaches. Cursor, for instance, doesn’t rely on a single model to generate code, according to the same reporting Misryoum reviewed. So the market pitch is converging a bit, which is exactly why Factory is leaning into “switching” as the center of gravity.
The startup’s customer list reads like a who’s who of big, complex engineering orgs. Factory says it includes engineering teams at Morgan Stanley, Ernst & Young, and Palo Alto Networks. In an enterprise setting, that kind of adoption isn’t usually instantaneous—it tends to come after security reviews, workflow tweaks, and those meetings where nobody wants to be the first person to say it might be risky. Somewhere in that process, someone probably has the coffee cooling beside a laptop fan that won’t shut up.
Competition is already crowded. Anthropic, maker of Claude Code, as well as Cursor and Cognition are among the companies vying for dominance in AI-assisted coding. Still, Misryoum newsroom reported that investors believe there’s room for at least one more player. That belief usually comes down to a simple idea: even if many teams want “AI that writes code,” they may not all want the same product surface—agent workflows, model flexibility, and enterprise integration can divide the market pretty fast.
Factory’s origin story is also notable, because it doesn’t read like the typical “grandfathered into venture capital” script. The company was founded in 2023 after Matan Grinberg—then a PhD student at UC Berkeley—cold-emailed Sequoia partner Shaun Maguire. They bonded over mutual academic interest, and Misryoum editorial desk noted that Maguire’s PhD from Caltech is in the same area of physics Grinberg was studying. Maguire then convinced Grinberg to drop out and launch Factory, with Sequoia backing the startup at the seed stage. It’s one of those details that sounds small until you remember how rarely founders actually get the combination of time, mentorship, and conviction right.
Factory’s latest raise basically turns that conviction into a mandate: build something enterprises can trust, make the model flexibility real enough to matter, and prove that agents—rather than just autocomplete—can fit into the messy rhythm of engineering teams. And, honestly, the next question is whether “switching between models” becomes table stakes as quickly as it sounds, or whether Factory can make it feel like magic in the day-to-day coding loop—if not immediately, then soon enough.
