It is nothing more than that. Everything sold today under the word AI pays off in exactly two places: more orders come in, or the same work takes less time. This is my application – which role it is for, you decide. Whether it becomes a post, a department of its own, a contract or a rejection is your decision.

More than half of German companies already work with AI. The question is no longer whether – but who takes responsibility for it in your company.
57 %
Your competitor already works with AI. Do you?Did you know: 57 % of companies use AI, up from 20 % two years ago. The gap to those who wait grows every month.
59 %
Who looks after AI in your company: IT, marketing, sales – or nobody?Did you know: 59 % do not use its potential at all, and not a single company uses it fully. Buying a licence means buying AI, but it changes nothing yet.
66 %
Can your people do what the law has required since February 2025?Did you know: the EU AI Act (Art. 4) obliges companies to ensure their staff are AI-literate. 66 % rate this competence as low.
61 %
What if the majority is right?Did you know: 61 % say companies without AI have no future. One company in three already sees its existence threatened by AI.

What I bring
Marketing for HR (Human Resources)
Finding good people matters more every year. Recruiting today is marketing. An application almost always lands with HR first. That is why this belongs here, and not only in front of the management.

Get in touch →Nepulus in action
Each video walks through a real process step by step – ready to train staff and to demonstrate to management. The narration is in German.
No CAD file: Nepulus builds the 3D model from the data sheet dimensions. The bearing rotates, the cap lifts off, dimensions, breaking loads and seals are explained in animation. German voice-over.
From data sheet to 3D model to the finished video with voice-over, plus examples from the trades: the new roof in a 360° view inside the quotation. German voice-over.
Real RAPEX orders from HubSpot, processed with Nepulus: the field rep uploads photos, the quote is ready after 13 minutes. One click creates the order confirmation with installation dates, purchase orders, crew planning and invoices.
Rhodius Abrasives: six halls, six quotes, cost summary and audit report in one click. Hausbau Realisierung Ahlborn: the manufacturer's quote for hydrogen storage and a Bosch heat pump becomes our own quote with costing.
Nepulus reads the Excel bill of quantities with 22 lots, finds quantity errors in the client’s documents, prices the lots, pre-fills the prequalification form and compiles the evidence folder. After the award: order confirmation, crew schedule, purchase orders, monthly measurement.
Image, voice and lip movement are generated locally and openly labelled as AI. The next stage adds natural head movement and facial expression – and a personal voice from a short sample.
Narration voice and avatar: open-source models, licensed for commercial use, run entirely on-premise.
About me
Twenty years of management responsibility, most recently four years at a photovoltaic and electrical company with more than 140 employees – as Head of Marketing and Sales, responsible for marketing, sales management and processes. Before that at LEDKON, where the customers were called Deutsche Bahn and SodaStream. I know day-to-day business from the inside: the full order book, the ringing phone, the boss still writing quotations in the evening. And I know the other side: I have worked in an advertising agency, and one of my earlier companies had an agency department of its own. So I know fairly precisely how the sums are done there.
That is how this company’s turnover developed during my time there – up 220% in four years, around 34% a year, while the German Mittelstand grew by a few per cent in the same period. This is not my own assessment, it is written that way in my employer reference, signed by the managing director. You can read it here.
I have worked in an agency and I know the route a printed piece takes there: briefing, concept, draft, correction rounds, artwork. Several people, several weeks. At the end there is a good piece on the table – and nobody knows whether it achieved anything.
I produce the same printed piece in a day today – and you see beforehand what it is for.
Four years of photovoltaics, heat pumps and electrical installation. Head of Marketing and Sales.

Open PDFWhere this fits
I deliberately do not commit to a title. The task is described, and so is the benefit. Whether it becomes a post, a department of its own, a project or a contract, you can judge better than I can. The task matters more to me than the label.
Permanently employed, reporting directly to the management. If you want the task in house for the long term and have more in mind than what is described here.
If the task cuts across marketing, sales, administration and HR and you therefore do not want to assign it to one department.
Fixed term, with a clear start and end. Set up in a few weeks, then handed over to your people, with no lasting commitment.
I build it and keep it running, and you have no extra head on the payroll. Twelve months, then cancellable monthly.
Many companies have never filled this position and therefore struggle with the name. So that this is not an obstacle, here are the titles that have proven themselves in practice – pick whichever fits your structure:
Head of Digitalisation and AI · Chief AI Officer (CAIO)
One word in there is not decoration but a requirement: Head of. The task reaches into marketing, sales, administration and HR at the same time. Whoever fills it has to sit at the same level as your head of marketing and your head of sales – otherwise they negotiate their way through every department instead of working. Where the role sits decides more about the outcome than any job description.
In larger companies with their own IT department, one split has proven itself: IT owns operations and security, this role owns application and outcome. Putting both in one pair of hands regularly slows down both sides.
The next step
I show you what runs in my own business, and you tell me where things stick in yours. That saves us both time and travel. Just suggest three dates – evenings work too.

Five AI tools of my own
I do not come with a concept paper but with a complete system: five tools that build on each other and run today. More than 20 years of marketing and sales went into it. If you wish, I develop it further and tailor it to your company. Every tool runs on a computer on site, and no data goes to an outside service. This is a competitive advantage you cannot buy in.

Tools change little if nobody can use them with confidence. That is why training is part of it from day one: in Sapia, alongside day-to-day business. This is how I support HR with in-house training until the rollout has arrived in everyday work.
