There's a particular kind of risk that only becomes visible once it's too late.

It doesn't announce itself. It doesn't trigger alarms. It accumulates quietly in the background, in the permissions you granted without thinking, the integrations you didn't audit, the agent you shipped to production because it worked well enough in testing.

And then one day the agent does something it shouldn't. Money moves. Data leaks. A customer gets the wrong information at exactly the wrong moment. And the question you're suddenly asking, who's responsible for this and what do we do now, turns out to have no good answer.

This is the problem we built Mount to solve.

Why this problem, why now

We're living through the fastest deployment of autonomous technology in history. AI agents aren't coming. They're here. They're booking meetings, processing claims, executing trades, managing customer relationships, making medical referrals. They have access to real systems, real data, and real money. They take real actions with real consequences.

And almost none of them have been properly secured, assessed, or insured.

This isn't a criticism of the companies deploying them. The tools to do this didn't exist. The frameworks weren't there. The market hadn't developed. Everyone was moving fast because the competitive pressure to move fast was real, and the downside risk of moving fast wasn't yet fully understood.

That's the window Mount was built for.

What Mount does

Mount is the trust layer for AI agents.

We identify vulnerabilities faster than attackers do. We help you continuously improve your security posture. We certify your agents against rigorous standards. And we insure them, so that when residual risk materialises, you're covered.

The workflow is straightforward. You connect your deployed agents. We run real-time vulnerability scanning and produce a risk score, a clear picture of where you're exposed and how exposed you are. We surface the specific issues: prompt injection vectors, data exposure risks, permission sprawl, unauthorised action pathways, integration vulnerabilities. And we give you the tools to fix them.

Once your agents meet our certification standard, you can carry them with active insurance. Not as a theoretical backstop. As actual financial coverage for AI agent failures.

For the first time, you can tell your board, your customers, and your regulators: our AI agents have been assessed, certified, and insured. We know what they can do. We know what they can't. And if something goes wrong, we're covered.

Who Mount is for

If you're an AI deployer, a company running agents in production, Mount gives you the visibility you've been missing. You know your agents are doing things. You probably don't know everything they're capable of doing. We fix that.

If you're an AI builder, a team shipping agentic products to customers, Mount gives you a credential that matters in sales conversations. "Our agents are Mount-certified" is a meaningful statement to an enterprise buyer who's been burned before, or is trying to avoid being burned for the first time.

If you're an AI agent provider, a platform on which others build and deploy agents, Mount gives you the infrastructure to offer zero-risk deployment as a feature. Your customers get security and insurance. You get a stronger competitive position.

The name

Mountains are the oldest metaphor for challenge and ambition. You don't conquer a mountain by ignoring the risks of the climb. You map the terrain. You assess the weather. You bring the right equipment. You prepare for what can go wrong so that it doesn't.

The most ambitious ascents in history weren't completed by the people who ignored risk. They were completed by the people who took risk seriously enough to manage it properly.

That's what we're building Mount to do for AI. Not slow it down. Not create obstacles. Help the people doing the most ambitious things get to the top safely.

A note on where we are

Mount is backed by Y Combinator and built by a team that came to this problem from security, insurance, and AI. We're working with AI deployers, builders, and providers who want to get this right, who understand that the era of hoping nothing goes wrong is over, and that the competitive advantage now belongs to the teams who can move fast and move safely at the same time.

If that's you, we'd love to talk.

The mountain isn't going anywhere. Neither is the risk. The question is whether you climb it prepared.
