A real legal entity with production accounts across your services. Zero integration. Zero project overhead. Just a customer you can break things with.
You can't use employee accounts for destructive testing. Synthetic data doesn't catch real edge cases. Creating test entities internally is bureaucratic hell. And you definitely can't ask customers to be your guinea pigs for model rollouts.
You need to test prompt injection defenses, rate limit edge cases, and model behavior under adversarial queries. But there's no one you can safely break things with.
New model weights? Infrastructure changes? You need real production testing before general rollout, but creating proper test accounts is a multi-week project.
EU AI Act needs ongoing validation logs. You need auditable proof that safety guardrails work in production. Unit tests don't cut it.
You want to catch quality degradation before users notice. But setting up proper canary testing with realistic interaction patterns? That's a whole team.
A real company. Real accounts on your platform. Real API keys. Real usage that looks exactly like a customer—because we are one. Just not one that matters if things break.
Deploy your new model to our accounts first. We run your test scenarios, you see real behavior before public release.
We run prompt injections, edge cases, and stress tests you can't run on employee or customer accounts.
Baseline quality checks running 24/7. We alert you when responses degrade before your users notice.
Banks solved this with Koivu GmbH—a real company that exists solely to have bank accounts and run transactions. We're the same concept for AI. You don't install anything. You don't integrate anything. You just give us access like any customer, and we become your expendable test entity.
We're not simulating a user. We ARE a user—with all the real-world infrastructure that comes with it.
Your AI agents need to interact with real services. Financial APIs, payment systems, crypto wallets, productivity tools. We can test these integrations without you needing to provision test accounts, fake credit cards, or sandbox environments. We're the real deal.
Concrete examples of what we actually do with our accounts
We run the latest prompt injection techniques from academic papers and red team forums. DAN prompts, role-playing bypasses, encoded instructions—we verify your guardrails hold up.
Baseline test suite runs every 6 hours. Standard reasoning tasks, factual recall, instruction following. We catch when your 95th percentile latency creeps up or response quality dips.
We intentionally hit your rate limits to verify: Are errors clear? Do retries work? Does the UI handle it gracefully? We test what happens when things fail.
Complex conversations that test context maintenance, long-term memory, and reasoning chains. The stuff that breaks in production but works in your eval suite.
Unicode edge cases, massive context windows, nested code blocks, malformed inputs—we maintain a library of things that historically break AI systems and run them continuously.
Want to compare two model versions on real usage? We run identical workloads against both and give you comparative metrics. No user impact.

We're currently working with teams at 3 major AI labs. Looking to expand to 5 more this quarter.
The original Koivu has been running real transactions through Swiss banks for years. They're a legal entity that exists solely to be a test customer. Banks don't install anything—they just have Koivu as a client. This same pattern works perfectly for AI services.
We're not asking you to change your infrastructure, install agents, or give us special API access. We're literally just a customer account. Your existing auth, rate limiting, monitoring—everything works exactly as it does for real users. Which is the point.
Our founding team includes former QA leads from scaling AI companies. We know the pain of "we need to test this but can't use customer accounts" and "the unit tests pass but production still breaks." This service exists because we needed it ourselves.
Every team has different needs. We start with a pilot, prove value, then scale.
Note: We're not a SaaS product. We're a service company. Setup takes 1-2 weeks (account creation, access provisioning, test scenario alignment). We move fast but deliberately.
Or your compliance headache. Or that edge case that keeps breaking production. We're happy to discuss your specific situation—no sales pitch, just shop talk with people who get it.
