We have raised $200M at a $5B valuation to scale self-improving software development in the enterprise. @FactoryAI has grown to serve hundreds of thousands of developers at companies including RBC, Adobe, Nvidia, T-Mobile, and Palo Alto Networks. We will use this capital to accelerate our investments in research, product, and global go-to-market.

I’ve been a huge fan of @dexhorthy and @0xblacklight for a while now. Two of the most ambitious polymaths I’ve ever met. Honored to make it official and join forces.

Today, @humanlayer_dev is joining Factory. HumanLayer is a multiplayer coding agent IDE and cloud for running agents locally or in the background. Together, with @dexhorthy and @0xblacklight we're building the future of software factories for entire engineering teams.

We got drunk, going from a world where only certain specialists can build things to a world where anyone can build anything. Now the hangover is setting in. Just because you can, does not always mean you should
narrative violation: preferences will swing back from DIY vibe-coded software to super secure industry-leading SaaS solutions. while it's super easy to build anything, endlessly protecting and securing it is super hard...and teams want to sleep at night.

Imagine if everyone had the tools to shape intelligence itself. That day is today. Today we launch the Trajectory platform - the easiest and most intuitive tool to post-train models of your own. The foundation for continual learning. With just a few agent prompts, you get access to a full creative suite to train, eval, and deploy trillion parameter models. On top of that, we believe in a future where you don’t just shape your model once, it also keeps learning on its own from the world around it. We’re releasing two research previews. 1. Continual grading scales your taste, so your model learns what good looks like from far more than you could ever grade by hand. 2. GS1, a new algorithm that lets models learn directly from what they do in production. We’ve now raised 60M, with a new round led by @Sequoia at a 300M valuation to democratize the most powerful technology of today - training models - so that the lawyers, doctors, and engineers of the world can own their own intelligence. You know what good looks like, now go build it. Own your own value function with Trajectory.

bragging about how many agents you have running in parallel in 2026 is like bragging about how many functions you have running in parallel in 2016. what are you actually getting done? in @agent_wrap's case, the answer is: a lot
I estimate the number of agents per user will keep doubling every six months. Here's a look at some of the runtime changes we made to handle that growth.

Thrilled to welcome @Yoni_Michael, @KostasPardalis, and the @typedef_ai team to Factory. People often over-index on the code generation step. Enterprise agents live or die by the data. Nobody understands that problem better than the Typedef team.
Factory has acquired @typedef_ai. Typedef builds a context layer that helps agents understand enterprise data. Together, we’ll give Droids, and the engineers that work with them clearer lineage and evidence to plan migrations, debug pipelines, and refactor models.

I would be remiss not to mention the key role @brexton played as angel investor / FDH (forward deployed husband) in bringing @sonofalli to the factory team if your investor doesn't help recruit their spouse, can you be sure they have conviction?
A partnership that began in the trenches of the elementary school playground 🤝

Alli is one of the most naturally gifted and hard-working people I've ever met. Thrilled to welcome her to the dream team we're building at Factory. If you're a start up looking to get up and running with Factory, what would you like to see from @sonofalli and the team?
Very excited to welcome @sonofalli as VP of New Media and Startups Marketing at @FactoryAI.

We're excited to share our customer story with @claudeai featuring Factory co-founder and CEO @matanSF. We cover topics like how @AnthropicAI frontier models in @Droid are enabling engineering teams to handle long-horizon tasks across large codebases, what it will take to build a fully autonomous "dark factory" for software, and more. youtube.com/watch?v=N6FkmdL0…

Annoyed and disappointed to see that the @FactoryAI office interior design is not second-tier but actually quite tasteful
