Step by step — and what each step costs

We make the knowledge your company depends on verified and usable — in steps you commission one at a time. Here you can see what each step includes, how long it takes and what it costs.

For mid-sized manufacturers of industrial equipment — from Cassel AI, founded by Cord Cassel, himself a manufacturer for thirty years.

Steps and prices

Start small. Always only the next step.

We offer steps that build on one another.
With each step, less work waits on a few individuals.
After Steps 1 and 2, a department already finds in its own documents what it has to ask a colleague for today.
After every step, you decide again.

Assessment

What you get

Findings, not gut feeling

You know where your knowledge lies, which processes cost the most time and which step to start with.

What's included

Half a day with you on site
where in your processes knowledge is searched for and depends on a few people
a sample from one department’s documents, around 100: duplicates, outdated versions, contradictions
a short written report with the recommended first step

An example

At the packaging machine maker, the sample from service shows four versions of the same maintenance manual, two of which contradict each other. Recommended: Step 1, then Step 2 for service.

€990 credited if you commission a step within three months

Half a day on site; the report follows within a week. Your effort: half a day for the managing director, one hour with the head of the department.

Add-on service · Available with any step

Knowledge retention

What you get

Secured, not lost

What your expert knows from experience is on record in your company, verified — even if they leave later.

What's included

Structured conversations with an experienced expert, along real cases from your company
recorded only with consent
the expert checks what has been made of the conversation
verified entries in Langdock (up to Step 3) or the knowledge base (from Step 4), each linked to the case that prompted it

How your people gain time

Questions that only they could answer so far are answered by the secured knowledge, with sources. The expert is asked less often.

An example

At the test equipment maker, the application engineer will retire before long. In conversations along his special solutions, his knowledge becomes verified entries.

More examples →

from €2,900 per expert

Your effort: at most three half-days per expert for the conversations, and half a day for their review.

If the expert has already left, we secure what they left behind — their quotations, project files and cases. What was only in their head cannot be brought back.

A typical start: initial assessment, Step 1 and Step 2 for one department — together from €6,800.

Steps 1 to 3

With Langdock

Langdock is the AI platform of a German provider: your people work in it with AI and with your company’s knowledge — through access and rules you control, instead of private accounts.
Your staff use it to work with AI and with your company's knowledge.
You control access — instead of private AI accounts that no one has an overview of.

Step 1 · Everyone in the company, no documents yet

Langdock for your company

What you get

Controlled, not private

Everyone in the company works with AI — in a tool you control, rather than in private accounts.

What's included

Langdock set up for everyone in the company
access, permissions and roles
rules for use, agreed with the works council
an introduction for everyone

How your people gain time

Drafts of texts, translations and summaries come from Langdock. Your people check them instead of starting from scratch.

An example

An enquiry from a French customer translated and the reply drafted — in Langdock, with an approved model, instead of in a private AI account.

More examples →

from €2,900 once per company

One to two weeks. Your effort: one meeting with your IT, a half-day introduction per group.

Step 2 · Per department, with its documents

One department

What you get

Finding, not searching

The department asks its own documents and gets the answer with its source.

What's included

up to 1,000 documents of the department cleaned up and sorted by topic
we put duplicates, outdated versions and contradictions to your expert as a catalogue of questions and decisions — they answer, we prepare the data
available to the department in Langdock
a training session
a report after four weeks of use
more than 1,000 documents: Steps 4 and 5

How your people gain time

The documents are cleaned up and in order. Your experts stop searching and are asked less often.

An example

Applications engineering asks: “Have we ever built a palletiser for bagged goods?” — and gets the three projects with their sources.

More examples →

from €3,900 per department

Three to four weeks. Your effort: half a day for the managing director, a good two days for one of your experts, who settles questions while the data is cleaned up and categorised, a half-day introduction per group.

Step 3 · A task that Langdock takes over

An agent or workflow

What you get

Approving, not doing it by hand

Langdock handles a recurring task; your people check the result and approve it.

An agent is a helper in Langdock that your people instruct in the chat — for example: “Write a quotation text from these three projects.” A workflow starts by itself when something happens — for example when an enquiry comes in: it reads it, assigns it and adds the right documents. Both deliver a draft; your people approve it.

What's included

A task that someone does by hand today, broken down and built in Langdock — as an agent your people address in the chat, or as a workflow that starts by itself
rules: what it may read, what may run without approval, who approves
test cases before it goes live
introduction in the department
a review after four weeks

How your people gain time

The task runs in Langdock. Your people approve instead of doing it themselves.

An example

A workflow reads every enquiry, recognises the product line and application, and gives the engineer the three most similar projects as a draft.

More examples →

from €4,900 per agent or workflow

Two to three weeks. Your effort: half a day for the department that does the task today.

Step 1 is the prerequisite for everything else. Step 3 can also follow Step 1 directly; if an agent needs a department's knowledge, Step 2 comes first. ERP figures, authoritative answers and applications such as draft quotations start with Step 4.

Steps 4 to 6

With the knowledge base

The next stage, once Steps 1 to 3 are working in your company — after a few months at the earliest.

Up to Step 3, your verified knowledge sits in Langdock; there your people reliably find what is in your documents.
The knowledge base comes in where the current version and the figures matter: it knows the item master, prices and status from your ERP, excludes what is outdated, discloses contradictions and backs every statement with section and date.
On top of it we build applications that produce results themselves, which your people then only need to check.
Langdock remains the platform your people work with, for the knowledge base too.
The applications are custom-built for exactly the way you work. Because this is where the promise is greatest, you pay half of each only once your people work with it.

What is the difference? →

Step 4 · Once per company, with the first Step 5

Your knowledge base

What you get

The current version, not every version

With the figures from your ERP, without outdated material, contradictions disclosed — every statement with section and date.

What is the difference? →

What's included

Your knowledge base set up in your own Microsoft Azure account
connected to Langdock so your people can reach it there
access, permissions and roles
rules: what may go in once checked, and who approves
one meeting with your IT

How your people gain time

As part of the first Step 5: the first department finds what it needs there from day one, with sources — and Step 6 builds on it.

An example

The knowledge base starts with sales as the first department. Service and engineering follow later — in the same place, under the same rules.

More examples →

from €11,900 together with the first Step 5

Two to three weeks, alongside the first Step 5. Your effort: two days of your IT's time; we do the set-up.

Step 5 · Per department, with all its documents

One department in the knowledge base

What you get

One place, not many folders

All of the department’s documents and the figures and business documents from your ERP, verified and in one place — available in Langdock, with sources.

What's included

All the department’s documents cleaned up and sorted by topic
we put duplicates, outdated versions and contradictions to your experts as a catalogue of questions and decisions — they answer, we prepare the data
figures and documents from your ERP: prices, items, bills of materials and all kinds of business documents, from quotation to invoice
available in Langdock, with sources
a training session

How your people gain time

Answers with figures come with their source. Your experts no longer search folders and the ERP at the same time.

An example

Applications engineering asks: “Which palletisers for bagged goods have we built, and what did the control system cost?” — and gets the projects with sources and the prices from the ERP.

More examples →

from €19,900 per department

Four to eight weeks per department. Your effort: about two hours for the managing director, two to three half-days per expert for interviews and checking.

Step 6 · Per application, on one department's knowledge

One application

What you get

Checking, not writing from scratch

The application produces results such as draft quotations; your people check them and approve.

What's included

An application for the department, such as draft quotations — built to a specification for your company
it works with the verified knowledge and the figures from Step 5
every statement with its source; your people check and approve
test cases before it goes live
involvement of your people and the works council
training for the group that works with it

How your people gain time

The application writes the draft. Your people check and approve instead of writing every result themselves.

An example

The enquiry becomes a draft quotation — structured on comparable projects, prices and bills of materials from the ERP, every statement with its source.

More examples →

from €28,000 Price per specification; half payable only once the agreed usage is reached. What counts as usage we agree together in advance; it is measured in your own systems.

How usage is agreed →

Six to ten weeks per application. Your effort: about one day a month for the managing director, two to three half-days per expert, one training session for the group.

You commission Step 4 together with the first Step 5 — an empty database helps no one. If a department has already had Step 2, its cleaned-up documents are carried over. Steps 5 and 6 are repeated per department and per application. From Step 4, a development partner we choose together with you does the building; your contractual partner remains Cassel.

Running costs and terms

From Step 4, monthly support is added, from €1,200 a month: running the knowledge base, maintaining the knowledge, a named contact.

All prices exclude VAT. You pay the Langdock licence directly to the provider — according to its price list from €20 per user per month (as of October 2026). From Step 4, with the knowledge base, the costs of your Microsoft Azure account are added; for these we expect roughly €150 to €450 a month, depending on data volume — the exact figure is in the quotation. What your company needs exactly is shown by the initial assessment.

The prices apply to everyone. The first companies receive a substantial discount in return for something: Cassel may use your company as a reference. More under “Why Cassel AI?”

The first step is a no-obligation conversation, under a non-disclosure agreement if you wish.

For your IT, engineering and works council

What your IT will be asked to do — and what not

This page gets passed on — to the IT manager, the technical director, the works council. For them, it sets out who does what, who builds and who operates. Everything else, down to the permissions list, we clarify in a conversation with your IT.

What your IT does

Set up the accounts, review and approve the permissions concept and the Langdock roles, and from Step 4 a Microsoft Azure account — your company's cloud account with Microsoft. That is a few days in total, not a project role. Running and maintaining the knowledge is not your IT's job.

What Cassel does

Prepare and verify your knowledge, set up Langdock — permissions and rules —, have applications built and accept them, involve and train your people, and provide monthly support from Step 4 onwards.

Who builds

Concept, preparation, rules and introduction: Cord Cassel and Spencer Robens. Cord Cassel sets up Langdock, with a Langdock specialist where needed. From Step 4, a development partner builds to our specification; we choose which one together with you beforehand. Your contractual partner remains Cassel, including for the software; we accept everything before it reaches you. The rights to the software lie with Cassel: if a development partner drops out, another continues to the same specification. Operation and data sit in your Microsoft Azure account.

Who operates

For Steps 1 to 3 you only license Langdock, directly from the provider; from Step 4 your Microsoft Azure account is added. Both belong to you and stay yours. From Step 4, Cassel provides monthly support: operation, maintenance of the knowledge, a named contact — as a service provider with access you can withdraw at any time.

Rules and records

You decide what an agent may read, what may run without approval and who approves — we write it down before anything runs. The works council, the data protection officer and your IT receive a written statement of what is read and what is logged.

Your people and the works council

The goal is growth, not job cuts: the time gained is meant for new tasks. We recommend committing to this in writing before the start. The works council is involved from Step 1, before anything is set up. Nothing is ever measured per person.

Standard where possible. Tailored where it counts.

Every solution is tailored to what only your company has: your terms, your processes, your way of costing a quotation or tracking down a fault.

This is not a kit of separate tools, each bringing its own data. All applications work on the same knowledge base and under the same rules. What matters is that your process is mapped correctly — that is what Cord Cassel's thirty years in industry stand for.

Not a configurator: a configurator needs rules that someone sets in advance for every variant. The applications work with what your company has already built and written — comparable projects, verified knowledge, figures from the ERP — and your people approve.
