Your team already uses AI.
Now make it run the work.
Chat tools help one person with one task, because that person holds the business in their head. Ortelian builds one shared model of your company, redesigns the process on site and deploys agents inside the tools your teams already use. Nothing to migrate.
Based in Belgium, on site across Europe and the US. Hosted in the EU. Three new partner deployments per quarter.
The gap
Models get capable fast. Organisations adopt them slowly.
Almost everyone on your team now uses ChatGPT, Claude or Copilot for individual tasks. Yet quotes still wait days for checks, supplier delays still take four people to untangle and compliance files still wait weeks on documents. A smarter model next quarter will not close that gap, because model intelligence is not what is missing.
The world model
Without a shared model, each agent rebuilds context on every run.
Connecting agents straight to your CRM, ERP, email and documents gives them access without a map. Ortelian reconciles your scattered systems and external registries into a live ontology of your business, with contestable explanations attached to the objects they describe.
- 01 · Objects & linksEach real thing held once
Companies, people, orders, invoices and regulations resolved across your systems, with full source provenance.
- 02 · Contestable explanationsReasoning that can be challenged
Agents write sourced explanations onto objects as they work. New proof challenges and updates them instead of overwriting facts.
- 03 · Actions & MCPShared by every agent and tool
Ortelian’s agents act inside Slack and your systems of record, while Claude, Copilot and ChatGPT query the same model over MCP.
How the work changes
Redesign the process around agents. Keep the decisions with people.
Adding chat to an old process speeds up one step while leaving every handoff and wait intact. Our forward-deployed team works alongside the people who do the job, strips out the manual chasing between systems and tests agents on real examples until they pass.
01Supplier delays14 steps → 3 decisions
From four people chasing one late part to one decision.
The planner approves the re-plan. Sales sends the customer updates.
02Non-standard quotes4 lookups → 1 approval
From quotes waiting days for checks to quotes ready to approve.
A commercial manager approves discounts outside standard rules.
03Compliance & tender reviews20+ files → cited gaps
From checking policies and contracts one by one to a cited review list.
Your specialist reviews flagged gaps and signs off the submission.
04Invoice exceptions3 inboxes → 1 case
From emailing buyers and the warehouse to approving a prepared case.
Accounts payable approves each prepared exception.
05New customer setup3 queues → 1 setup
From a chain of emails to an account set up in every system.
Finance approves the credit limit. Legal signs off non-standard terms.

Each agent only reaches
what its job needs.
You decide what it can read, what it can change and what it never sees. Anything that leaves the company waits for a person.

Chat tools, workflow builders and consultancies each solve a fraction.

Who you’ll work with
You work with Laurens directly.
Laurens founded Ortelian and builds the platform, so the person who maps your work builds the agents. Before this, he founded GTM Sigma, building go-to-market and knowledge systems for B2B companies. That work is where the idea for Ortelian’s world model came from.

Questions
Frequently asked questions.
What is a world model for knowledge work?
A world model for knowledge work is a map of what shapes a company’s work, inside the company and in the world around it, that agents query instead of rebuilding it from tools on every run. It has three layers: the data that keeps it current, a graph of the companies, people, places, regulations and events that matter and how they relate, and the knowledge attached to those things. Every fact keeps its source. We build and maintain one for every company we work with, and every agent works from it.
Where do you work?
We are based in Belgium and work with companies in Europe and the US. We travel to your offices and work on site with your team. The platform is hosted in the EU.
Do we need to move to a new tool?
No. Agents work inside the systems you already use: your CRM, your systems of record, Slack, Teams and email. Your data stays where it is, and your team keeps working where it works today. Ortelian’s own app is where agents, workflows and limits are set up and monitored.
Who is Ortelian a good fit for?
Companies with complexity in their team, product, service or market, where the work depends on context that no single system holds. If a process is simple, an agent doesn’t need that context and you probably don’t need us. We work best with teams that want to become AI-native and are ready to move quickly, give feedback and put improvements into practice.
What does AI-native mean?
We use four questions. Does AI own actual work, rather than only answer questions? Do agents share a current picture of the business and the world around it? Has the work been redesigned around what AI can now do? Do agents improve from feedback and evaluations? A company that can answer yes to all four is AI-native.
Why do you work on site?
To redesign a process, we need to know how it really runs, including the steps nobody wrote down: the chasing, checking and workarounds that happen in email, chat and conversation. We see those by working next to your team, and being there lets us redesign the work with the people who do it.
What do we need before starting?
An internal owner, ideally a founder or someone on the leadership team, with the authority to make decisions and drive implementation. A team willing to test, give feedback and iterate with us.
How is Ortelian priced?
Every engagement starts with an audit. We agree the scope, support and commercial terms with you before work begins. We don’t publish a price list.
How do we know the work is good enough?
Evaluations built into Ortelian test whether agents meet agreed standards on real examples of your work. They keep running after launch and track quality, cost, completion time and human effort.
What can an agent do on its own?
We agree what agents can access and what they can do. Work inside the company, like updating records or preparing a report, usually runs on its own. Anything that leaves the company, like an email to a customer or an invoice, waits for a person’s approval by default. Those limits are part of the deployment and are reviewed as the work changes.
What happens after launch?
Your team runs the system, or we run it for you. Workshops during the build prepare your team to own it. Either way, we host the platform, review failures, update the knowledge, instructions or workflows, and the evaluations keep running to show the work stays at the standard. Over time your team takes on more of the day-to-day changes, and we spend our time finding where the work is held up next.
