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.

our per-engineer velocity has surged these last few months workstreams, delegations, better review automations and much more robust validation loops

I actually agree with a lot of what @poteto is saying except for the central point. IMO most people don't have actual software factory systems. They've just made it much easier for people to ship with AI, so they assume the category doesn't exist. That's more a lack of vision than anything else. Our conceptualization of a software factory is a system where every piece of work goes through the same stages to standardize the process not the work output. For us, this standardized process begins with what we call a signal. This is anything that tells you how your software should evolve, including the first signal that your software should exist at all. A Slack thread, a Linear ticket, a Sentry alert, a failing CI job, a tweet, someone's idea. There's two ways in for a signal. A person picks it up and builds it with Droid, or a workstream picks it up on its own, triages it against a goal someone set, and has droids write the spec and open the PR. Most work still starts with a person, but a growing share comes from workstreams. Then every change goes through the same checks no matter who or what wrote it. Droid review, security review, a risk judge that can't see who wrote it, CI, and an agent that QAs it on a live preview. Your validation has to be really high quality whether a human or AI built it. The goal of validation is to hillclimb your "regret-free merge rate" until you can automatically merge most changes (or fix them until they can be automerged). Then it ships, and when something breaks in production we trace it back to the PR that caused it. That becomes another signal. It's also how we know if the checks actually work. If the risk judge approved something that later broke, we find out. It's the same way we let self-driving cars on the road. Nobody just flipped a switch. We agreed that once they crashed less than human drivers, they could drive. Do the same thing with code. Once AI-written changes break things less often than human ones, and you can actually measure that, you let them merge. That doesn't mean you turn on automerge tomorrow. Most of our changes still get a human stamp. But once you have automerge, workstreams and a risk score together, you basically have software that improves itself from the signals you choose to track. The human element becomes obvious if you have a system like this. People remove themselves from the actual process line and begin to define the rules by which the process operates. What to watch, goals and owners, skills, review guidelines, and how much autonomy each workstream gets. They're the regulators. I think the 1920s factory that a lot of people picture is the wrong idea. That was people doing the same motion on a line all day. This is closer to a Star Trek replicator. You say what you want and it gets made, because the patterns are already stored and how things get made is the same every time, and checked every time.
hot take: you don't need a software factory, and i don't love the term. it's just marketing all you need is good software engineering and investing your tokens in the right places. the more deterministic the better (and token efficient)

Factory is now available in @MicrosoftTeams. Start a channel post, mention @ Factory, and describe the task: the repo, the outcome, and how to check the result. Factory’s agent, Droid runs the work and posts status updates in the thread, with a Stop button on the status card.

Cyberattacks now outpace the defenses of even well-resourced organizations. Factory can help. Introducing Factory Wargames: We will simulate a nation-state level attack on your company's infrastructure and cover the cost. Apply below and if selected, we'll run the simulation, share our learnings, and Droids will help with the fix for free.

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.
