We don't want to build your software. We want to make you the market leader.

The software was never the point. We build the part that's actually hard — the algorithm, the platform, the AI system — and what you get out of it is an advantage competitors can't copy.

What would it take to make your competitors your customers?

It's a real question with a real answer. One client got all the way there, and it took two moves, two years apart.
  1. When we met

    “Planning one job takes 23 minutes, and we still throw away a sixth of the film.”

    Signvision cuts window film to size. A single job might be 84 pieces for 14 different windows, no two the same. Somebody laid those pieces out along the roll by hand, and how well they did it that morning decided the margin on the job.

  2. What we did first

    We sat down and worked out the rules with them.

    Not a requirements document handed over and built to. Weeks of arguing about edge cases with the people who actually cut the film, until what they did by instinct was written down precisely enough to compute.

    We halved the waste.

    Their own measurement — one job, 14 windows, 84 pieces

    Material waste16.84%8.21%
    Planning time23 min30 sec
    Film costCHF 4,456.50CHF 4,039.20
    Cutting costCHF 420.00CHF 324.00

    That is a tenth off the cost of that job — CHF 513 in film and cutting — plus 4.2 hours off the shop floor. And it repeats on every job, for as long as they run it.

  3. Two years later

    Then came the move that actually made them the market leader.

    We built the algorithm into a B2B portal — folienzuschnitt.ch — and opened it to the trade. The firms Signvision had been losing jobs to signed up and started planning their own work through it. On Signvision's system. Paying Signvision to do it.

    Their competitors became their customers

    That is what made them number one for window film cutting in Switzerland. The portal now runs internationally.

The algorithm is the part most software firms cannot build. Selling it to the people you were losing jobs to is the part nobody thinks to suggest. Signvision did both, and that is the difference between a good supplier and a market leader.

You probably have one of these. You just haven't named it.

  • The thing that decides your margin depends on who's on shift that day.
  • Your best person does something by instinct that has never been written down.
  • You lose jobs on how fast you can quote, not on price.
  • Everyone in your industry solves this the same slow way, and nobody has bothered to fix it.
  • You hold data nobody outside your company has.

If two or more of those are true, that's a conversation worth having.Book 20 minutes

Not a full-service agency. The hard part.

Five things we're genuinely good at. Everything else we can bring — but these are the reasons to call us rather than somebody closer.
  1. 01

    Algorithms & optimization

    When the answer has to be computed rather than configured. Cutting and packing, scheduling, routing, pricing, simulation — anywhere a better method is worth real money. This is where a physics background stops being trivia.

  2. 02

    Business systems & portals

    Customer portals, internal platforms, B2B systems built around how your business actually works — instead of bending your business around software somebody else designed for a different company.

  3. 03

    Integrations

    ERP, e-commerce, CRM, accounting, PIM, payments. Getting systems to exchange data cleanly and keep doing it. Unglamorous, and usually the fastest payback in the building.

  4. 04

    AI that survives contact with the job

    Automation of repetitive work, document and knowledge systems, custom agents. We'll also tell you where AI is the wrong tool — that's most of the value we add on this one.

  5. 05

    What ties the other four together

    Fractional CTO

    Somebody senior on your side of the table. With Signvision that meant sitting down and working out the rules of the business before a line of code existed — which is where the algorithm came from, and why it was worth building. Architecture, vendor decisions, technical due diligence, and getting stalled projects moving again. We've run a business since 2002, not just billed for one.

A few others.

Much of our work over the past twenty years was delivered white-label through agencies, under terms that don't let us name the end clients in writing. Several are names you'd recognize — ask us in person.

Public sector

State development bank

Complete public web relaunch for a publicly owned regional development bank: frontend architecture, amortization-schedule calculators, eligibility questionnaires, complex interactive forms with server-side processing, and full statutory accessibility conformance.

Lead generation

Software comparison platform

Public acquisition funnels, an admin portal and a customer-facing B2B portal in one system. Leads are captured, enriched, qualified and routed to paying customers; the platform also runs invoicing, credit notes, dunning, an embedded CRM and financial dashboards. Integrated with HubSpot, Salesforce and Integrate.

Retail

International footwear brand

Product lifecycle platform: collection management, model development, stock and real-time availability across e-commerce and retail stores, synchronized with Shopify, PIM, Microsoft 365 and Google services.

SaaS

Reputation management platform

End-to-end platform for managing business profiles, reviews and fake-review removal, with integrations across CRM, email, accounting, direct debit and collections — plus a white-label portal so agencies could resell it under their own brand.

THE PEOPLE, NOT THE LOGO

Two of us you'd deal with directly.

Six people in total, in Neuhausen near Stuttgart — developers, AI engineers and project management. Small on purpose: nobody sits between you and the person writing the code.

Founder · Managing Director, Technology

Physicist — Diplom, University of Stuttgart, 2003, thesis on solutions to the Newton–Schrödinger equations. I started building commercial software in 2002, during the last stretch of the degree, and never stopped: twenty-plus years of mathematical algorithms, database engineering, portals, integrations and cloud delivery. The physics matters less as a credential than as a habit — take a problem nobody has structured yet, break it down, and work out what's actually true before writing any code.

QUESTIONS

The things people ask us first.

What's worth knowing before the first conversation.

With a conversation, not a form that disappears. Twenty minutes with an engineer rather than a salesperson, on what you're dealing with and whether we'd be any good at it — no charge. If it fits, we scope it properly: approach, timeline and money in writing before anybody commits.

From a focused four-to-six week build up to platforms we've developed and maintained for years. If a problem is small enough for an off-the-shelf tool, we'll tell you which one to buy.

Yes, regularly. Inherited codebases, stalled projects, and systems whose original developer is long gone. It's a specific skill and a good share of our work.

Because the interesting question is never "can AI do this." It's whether the result lands in somebody's actual working day and stays there. We'll usually recommend automating two or three things that obviously pay for themselves before anything ambitious.

Stuttgart, Germany — a German engineering company, which is most of the reason clients come to us. We've built software for clients we rarely sit in a room with for years, and the nine-hour offset earns its keep: you send a question at the end of your day and the answer is waiting at the start of the next one.

No — our clients are European. Sebastian is spending time in Southern California to learn the market first-hand: how business gets done here, what companies are stuck on, who is worth knowing. If you're up for talking about your own business and answering a few questions, he'd genuinely appreciate it — just get in touch.
