Corridor Raises $25M in Series A to Secure AI-Native Software Development

Corridor just walked into a room full of AI-generated code and asked a simple question most teams are quietly avoiding: who’s checking the checker while the machine is typing faster than your best engineer on espresso? $25M later, the answer is getting louder.

Big nod to Jack Cable and Ashwin Ramaswami for taking Corridor from a living room operation in 2024 to a $200M valuation with Felicis leading the charge, backed by Conviction, Timeless, Artisanal Ventures, Lux Capital, Sunflower Capital, Datadog, SV Angel, and a sharp circle of angels tied to Anthropic, OpenAI, Cursor, Cognition, Factory, Lovable and more. When that many builders and backers lean in, it usually means something real is breaking underneath the surface.

Jack Cable and Ashwin Ramaswami didn’t stumble into this. Both came out of CISA where “secure by design” wasn’t a slogan, it was survival. Then they watched AI coding tools crank output 5 to 10x faster and realized traditional AppSec was about to get lapped by its own backlog. So they built Corridor to sit inside the workflow, not behind it. Code gets written, Corridor is already there. No lag, no polite reminders after the damage is done.

And bringing Alex Stamos into the mix as the security leader adds a layer of gravity you can’t fake. When someone who’s handled security at Facebook and Yahoo decides this is where the puck is going, you pay attention. Quietly, but seriously.

What stands out is how early they got signal. Within months, they were already protecting production code at companies like Cursor, Mercury, and GreyNoise. That’s not a waitlist story. That’s a “we need this yesterday” story. Different energy.

The real takeaway isn’t just the capital. It’s the timing. AI is writing more code than ever, and not all of it is clean, safe, or even understood by the person shipping it. Corridor is betting that security has to move at the same speed as creation or it becomes theater. So instead of scanning after the fact, they’re embedding guardrails at the moment of generation. Catch it when it’s born or chase it forever.
