Websites, software and workflow systems for the cultural domain.
We design and build the websites, the software and the integrated workflow systems that run value-driven businesses, artists and NGOs in the cultural domain: galleries, studios, labels, shops and foundations, and the back offices behind them.
What we do
Architecture, engineering, and the long haul.
We are a software services business for the art world and for value-driven businesses, artists and NGOs that need a system to hold up for years, not a website for a season.
Architecture & engineering
Shops, platforms and back offices on Laravel, Shopware, Shopify Hydrogen or WordPress. The stack is chosen for the problem and for the team that will live with it, not for fashion.
Integration & data
Shop, point of sale, bookkeeping and mail kept in step. Migrations rehearsed before they run and arriving with every record. DATEV, e-invoices, bank reconciliation.
Apps & devices
Native iOS and Android where a browser is the wrong tool: the scanner at the packing table, the inventory offline at the art fair.
Consulting & care
Holistic, stable and sustainable solutions for your workflow, written down so you can read why they work, and maintained so they keep working.
Selected work
Systems that run real businesses.
A selection of projects, each live and in daily use. Each page tells the brief, how it was realised, who took part and what it solved.

How we work
Understand. Build together. Publish. Keep improving.
A small full-service agency that goes deep, and stays close for as long as you want it to.
Understand the workflow
We start where the work happens: the packing table, the front desk, the inbox. We learn how things run; the system follows the work, not the other way round.
Build together, at eye level
You know your business; we know technology and communication. From your brief we propose a researched, informed solution and shape it together. Neither side dictates.
Publish and follow up
A rehearsed, seamless switchover: the migration is practised until the day holds no surprises. Then we stay close, watch the system in daily use and fix what only real use reveals.
Maintain, adapt and improve
Software is not static: it reflects its surroundings and is only useful if it adapts to them. That takes a reliable partner, so we stay by your side and improve your systems proactively.
About
A software services business for the art world. At work since 1999.
artworld solutions is the services arm of WL Artworld Solutions GmbH, founded in Berlin in 2015 as the company behind WrkLst, which thousands of professionals at galleries, artist studios, estates and other artwork-based endeavours run every day to improve their artwork-based workflows. We provide inventory and contact management systems and other technological solutions to the cultural domain, and to the value-driven businesses, artists and NGOs that want the same care.
We specialise in secure and efficient programming of the web, databases and the integration of software systems, and we offer consulting to find holistic, stable and sustainable solutions for your workflow.
The work is led by Tobias Vielmetter-Diekmann, founder of WrkLst: a software developer by training who also studied museum studies and art and visual history, building software for a living since 1999, beginning with his school's first website. Since then: hundreds of projects for a client base around the world, with a focus on the German Mittelstand, from simple websites to complete business systems that large organisations with many employees work in every day.
This agency is the culmination of that work, done with a small circle of long-standing collaborators for design, structure, systems development and consulting, who are named on each project.
What we believe
We love websites.
A website is the one place where you speak entirely for yourself: your philosophy and your stance, in your own words, your own order, your own pace. Over the past decade, social networks have become the most popular channels of communication and use that power for an agenda of their own: they steer attention in their interest, not in the interest of those who make the content or take it in. To us, a website is the antithesis.
So we build websites that inform rather than hook: no endless loop of triggered emotions, but good design and clear structure, led by what the visitor came for. The spirit of the early web with the craft of today: an individual, human way of communicating that keeps the original optimism of the web alive and offers a much-needed counterbalance to the enshittification of the technological vision of our time.
Optimized workflows.
Work is at its best when technology makes space for what makes us us and takes the friction out of the repetitive, bland parts. Bookkeeping shifted by hand from one system to the next is tedious, error-prone and dull; a workflow that is covered end to end and automated where it should be leaves room for the creative, human work that is enjoyable and motivating.
So we build systems that speak to each other, and speak openly: nothing locked away in one tool, nothing typed twice, everything you own exportable at any time. Open standards are a stance, not a feature. Your data is yours, your systems should outlive their vendors, and the people who work with them every day should feel the technology serving them, not the other way round.
Security and privacy.
In an age of endless data harvesting and profiling, the proper handling of personal information is not a feature but a duty. A system that holds the records of a business has to hold them for years: protected and maintained, not secured once and forgotten.
So we treat your data as what it is: entrusted, not harvested. We ask before we collect; what we host ourselves stays in Europe, and where a platform such as Shopify is part of the system, we say so and what it holds; we protect what we hold with the care a gallery gives a work in its custody, and we keep protecting it for as long as the system runs, because security is a habit, not an installation.
Sustainability.
Software has a footprint, in the electricity it draws, in the devices it wears out and in the systems it replaces. Most of it is invisible to the people who use it, which is exactly why someone has to care.
So we keep the footprint small: lean pages that load without waste, no tracking of individuals, nothing pulled in from elsewhere that does not need to be, and hosting that runs on renewable energy. And we build to last, because the most sustainable system is the one that is still running in ten years, with every record it ever held.
