The all-in-one intelligent workplace for your business

Third Rule builds the Intelligent Office for the new era of digital employees. It is one governed environment where your people, the software you already run and specialised AI agents complete real work together, while professionals stay in control of every outcome.

CLEON-aiOS is the technology behind the Intelligent Office. From day one it brings AI capacity to every part of your office process: it understands what needs to be done, picks the right digital employee for the job, carries the work across your systems and records every step, so nothing happens without your knowledge or approval.

With CLEON you get everything AI makes possible through one platform: no juggling multiple providers, and no investing in or maintaining the technology yourself. It is open by design, so you can plug in other AI and agentic solutions, and connect the software already in your technological landscape using the access rights you have in place.

A digital employee is an AI colleague that performs complete processes rather than single tasks: reading, drafting, checking, following up and coordinating across your systems. It retains context and memory, works within your policies and pauses for human approval on material actions.

No. Our founding belief is that AI should strengthen human capability, not replace human judgement. Digital employees absorb the repetitive work; your professionals review, approve and stay accountable for outcomes. We automate the work, never the responsibility.

No. CLEON connects with the office systems you already run, with 1,000+ connectors and growing. Digital and human employees work together on top of your existing technology, without disruptive migrations or major upfront investment.

Very little of either. There are no lengthy data migrations, and the environment is easy to use from day one across every age group, with an Assistant Mode for operational work and an Expert Mode for professional work. At early customers, 98% of users are active every week.

At early customers, aiNotaris is creating more than 3.5 FTE of additional capacity with 98% weekly active usage.

aiNotaris is the first industry solution built on CLEON: the Intelligent Office for the notarial market, one of Europe's most trust sensitive professions. It proves the model in an environment with sensitive personal data, complex dossiers and strict professional accountability.

On private Microsoft Azure infrastructure in the EU, not a public cloud and never a US-hosted one. Third Rule is built in the Netherlands, and your data stays on European soil.

Never. Customer data is not used for the training, fine-tuning or benchmarking of any public or private AI model, not by us and not by our providers. Your information is processed to complete your work, and for nothing else.

Before any AI reads a document, the Data Shield anonymises names, BSN numbers and other personally identifiable information locally, using advanced NLP and RegEx filtering, and encrypts the rest with AES-256. The model reasons on abstract logic, never on the identities of your clients.

Third Rule is ISO/IEC 27001:2022 certified, and compliant with GDPR, the EU AI Act, SOC 2 Type II and ISO/IEC 42001. Security documentation is available on request for vendor assessments.

Your professionals, by design. Material actions pause for human sign-off, every access, model call and action is logged, and nothing happens in your environment that cannot be traced back, reviewed and explained.

No. CLEON is model agnostic and selects the right technology for each task, which avoids dependence on any single Big Tech provider. Your data remains yours: you decide what enters the environment, how long it is retained and when it is removed.
