What I do with each company

I run five companies. That sentence tends to raise eyebrows, so this post is the honest tour: what each one does and what kind of posts it will generate on this blog. If you want the shorter version, it lives on the about page; the personal backstory is in who I am.

ANDERS IT

ANDERS IT does IT consulting for DACH SMEs: self-hosting, digital sovereignty, NIS2/GDPR and local AI. I am the founder, and the company is still young. It is built for questions like “can we get this workload off a US hyperscaler” or “what does NIS2 actually require from us” — the kind I want to answer with running systems instead of slideware.

Blog-wise, this is where the digital-sovereignty and self-hosting-for-businesses posts come from.

cloudsourced

cloudsourced is an EU-sovereign managed open-source hosting platform. I founded it because the gap between “I want to self-host this” and “I can responsibly operate this” is where most self-hosting ambitions die — the platform closes that gap while keeping the data in the EU and the software open source.

Expect posts about operating open-source software as a service: upgrades, backups, the unglamorous parts.

Avelia Health

Avelia Health is a privacy-first app for couples, from fertility through early childhood. I am a co-founder and the main developer of the app and the backend behind it. Health data is about as sensitive as data gets, so this is where privacy-by-design stops being a talking point and becomes architecture.

Posts from this corner will be about building consumer software when the honest answer to “what do you do with my data” has to be “as little as possible”.

DroidSolutions / KULDIG

DroidSolutions does app development from Leipzig; KULDIG builds digital culture products. This is my biggest role: I co-founded the company at the very beginning, created the KULDIG AppCreator, and led the IT for years. Today I am responsible for apps in production like the Leipzig App, the Partheland App, L-Charge, L-Energie, and Mein Brillant.

Posts here will lean toward development practice: tooling, project setups, lessons from client work.

Pauly Predictions

Pauly Predictions builds software for predicting physicochemical properties of chemicals — a UFZ spin-off. I am a co-founder, and in this team I do full-stack development and DevOps — the infrastructure the AI tool runs on. It is the most specialized company of the five: scientific models wrapped in software that chemists can actually use.

This one will show up when I write about turning research code into a product.

How the five fit together

They look scattered. The common thread: software you can trust because you know where it runs and what it does with your data. ANDERS IT consults on it, cloudsourced operates it, and the product companies hold themselves to the same standard with their own users. The blog collects the notes from all five.
