Our mission
Kyvvu makes AI governance enforceable. We believe autonomous AI agents will transform how organizations work — but only if they operate within clear, verifiable boundaries. Whether those boundaries come from the EU AI Act, industry regulation, or your own corporate values, Kyvvu turns them into runtime guarantees.
What we do
Kyvvu is the behavioral firewall for AI agents. Enterprises running agents in production need to prove that every action was authorized and within policy — but today’s tools only tell you what happened after the fact. Kyvvu sits inside the agent runtime and enforces policies in real time, on every step, with an immutable audit trail. It’s framework-agnostic and based on a formal trajectory-aware policy model. The result: agents that are compliant by construction, not by hope.
The key idea is that governance violations don’t live in individual actions. They live in paths. An agent reading a customer record is fine. An agent reading a customer record, then contacting an external system, then writing data back — that sequence may or may not be fine depending on context. Reviewing individual steps won’t surface the problem. You have to evaluate the whole workflow.
This approach — policies on paths — is documented in our research paper Runtime Governance for AI Agents: Policies on Paths, and informs every part of the platform.
The platform
We provide a production-ready runtime stack:
- Kyvvu Engine — the core runtime that evaluates policies on paths; sub-millisecond per policy evaluation; deployable as SaaS or on-premise
- Integration layer — SDKs for core Python, LangChain, and LangGraph; connectors for Microsoft Copilot Studio and MS Agent SDK; a local proxy for Claude Code; framework-agnostic REST API
- Policy library — plain-language rules mapped to EU AI Act articles, GDPR, and sector-specific requirements; extensible with your own policies
- Structured observability — hash-chained, tamper-evident logs of every intercepted behavior and every enforcement decision
- Incident escalation — structured incidents with full execution-path context, routed to your existing workflows
- Management dashboard — for developers to monitor agents and for CISO/legal teams to manage policies and review incidents
The team
Kyvvu is a small, focused team with deep expertise in AI, enterprise software, and regulated industries.
Founders
Jeroen Ghijsen — Co-founder & CEO. Jeroen was previously CEO of Metrological, a software company serving operators globally, and has two decades of experience scaling enterprise technology businesses. He leads Kyvvu’s commercial strategy, partnerships, and go-to-market.
Maurits Kaptein — Co-founder & CTO. Maurits is Professor of Applied Causal Inference at Eindhoven University of Technology (TU/e), with over 100 peer-reviewed publications spanning statistical learning, causal inference, and AI systems. He previously co-founded Science Rockstars (PersuasionAPI) and Scailable B.V. (acquired by Network Optix in April 2025). He leads Kyvvu’s product and engineering.
Team and advisors
We work with a small team of senior engineers and a group of advisors covering enterprise delivery, AI regulation, and commercial strategy. We’re intentionally keeping headcount lean until our enterprise motion is at scale.
Our story
Kyvvu was founded in late 2025 on a specific observation: organizations are deploying AI agents at an accelerating pace, but the infrastructure to ensure those agents behave according to organizational policy — at runtime, not in a post-hoc report — simply doesn’t exist. Prompting isn’t enough. Permissioning isn’t enough. The missing layer is runtime enforcement.
The EU AI Act codifies much of this need, but compliance is only one outcome. The more fundamental outcome is being able to deploy agents with confidence — knowing that whatever path an agent takes, your rules will be enforced before, not after, the action.
Today, Kyvvu runs in production across regulated industries in the Netherlands, delivered through authorized partners. We’re backed by pre-seed funding.
