Autonomous security testing, for every company that ships.
We are building Bringdown because the way software gets made changed and the way it gets tested did not. Teams ship every day with agents writing much of the code, and still get checked once a year by hand.
What we want to build
The goal is not a better scanner. It is to become the platform any company points at its product to have that product continuously attacked, proven broken, and handed back a fix, without hiring anyone or scheduling anything.
We are unreasonably interested in AI-native startups, because they are the clearest version of the problem. They ship fastest, they lean hardest on agents, and they have the least security help. If autonomous testing works for them it works for everyone.
Why we think this is possible now
Agents can operate a computer. That is the part that changed. An agent can stand up an environment, use the real product the way a person would, learn how it behaves, and keep going without being told each step.
That is a different problem from reading source code, and it is where the bugs that matter actually live: the ones that only exist once the thing is running.
Who's behind it
Bringdown is built by Julius Olsson, a 20 year old engineer from Gothenburg, Sweden, now based in San Francisco.
He has spent the last while building agent tooling and autonomous testing systems, which is a roundabout way of saying he kept building the thing that became this one.
Where we are today
Bringdown is in beta. We are onboarding design partners now, and they use the product free of charge for the initial period.
If that sounds like your team, join the waitlist. We read every one.
