Factory Raises $150M Series C at $1.5B Valuation to Scale Agentic AI for Enterprise Software Engineering

Conviction does not usually send a warning shot. It just moves. Matan Grinberg walked away from a physics PhD and aimed a cold email straight at a Sequoia Capital partner who spoke his language. No insulation, no choreography, just a clean bet on timing and instinct. That message didn’t just get a reply. It started a company.

Fast forward and Factory just locked in $150M in Series C funding at a $1.5B valuation, led by Khosla Ventures with Sequoia Capital, Insight Partners, Blackstone, NEA, Mantis VC, 20VC, and Evantic Capital all leaning in. Keith Rabois joins the board, which tells you everything about how serious this room just got. When that lineup shows up, they are not browsing. They are buying into a future they think is already late.

Matan Grinberg (CEO) and Eno Reyes (CTO) did not build another coding assistant whispering suggestions into an IDE. They built a Factory. And like any good factory, this one produces output at scale. Their “Droids” are not here to help developers code faster. They are here to take on the entire lifecycle. Coding, testing, documentation, incident response, migrations. The messy middle where real engineering lives. The part most tools politely avoid.

Watch the signal, not the noise. Revenue doubling every month for 6 straight months. Enterprise names like Morgan Stanley, Ernst and Young, Palo Alto Networks, Nvidia, and Adobe already in the mix. Legacy migrations collapsing from months into days. That is not a feature set. That is pressure on the entire software development economy.

The quiet flex is the architecture. Model agnostic. Air gapped when it needs to be. Comfortable inside the kinds of environments where compliance teams don’t smile and outages cost more than most startups will ever raise. Factory is not asking enterprises to change how they work. It is sliding into the chaos and organizing it from the inside out.

The lesson is sitting in plain sight. Winners in this cycle are not building tools. They are building systems that replace categories of work. Matan Grinberg saw that early. Eno Reyes engineered it into reality. The capital followed because the outcome is starting to look less like a bet and more like math.
