Web design and AI agency in Fellbach.
Web design and AI from a single source: OsAI is an AI agency in Fellbach, right next to Stuttgart, made up of exactly one person. Osman Öztopcu builds websites and web apps and brings AI into small businesses. Meetings happen at your premises around Stuttgart and in the Rems-Murr district, or by video call.
One point of contact, from the first call to handover.
OsAI is Osman Öztopcu. He founded the sole proprietorship in Fellbach in May 2026 and does every project himself: the conversation, the draft, the build and the ongoing care.
The offer is built for businesses without an IT department of their own, such as trades, medical and therapy practices or restaurants, where the owner decides whether something is worth it. As a small business under § 19 of the German VAT Act (UStG), OsAI doesn't charge VAT, so every price is final.

What local businesses ask first.
Short, honest answers.
Do you come on site?
Yes. Around Stuttgart and in the Rems-Murr district I'm happy to come to your business for conversations, workshops and training. Beyond that, the work runs by video call, anywhere in Germany. The Fellbach address is the registered office; meetings take place at your premises or online.
What does a website in Fellbach cost?
It depends on the scope: how many pages there are, whether copy and images already exist, and how many languages the site needs. You get your fixed price after the free 15-min intro call, before any work starts. It's a final price, since OsAI is a small business under § 19 UStG and doesn't charge VAT. You see the draft before you commit.
Do you offer AI training under the EU AI Act?
Yes. The AI training under Art. 4 of the EU AI Act is half a day for up to 10 people, with a certificate of attendance for each person, on site or online. Art. 4 has applied since 2 February 2025. In the version in force since 27 July 2026, companies that use AI take measures to support the AI literacy of their staff. There's no fixed number of hours and no mandatory certificate.
Do you only work with businesses from Fellbach?
No. On site I cover greater Stuttgart and the Rems-Murr district; by video I work with businesses all over Germany. The SANITECs Haustechnik reference, for example, is based in Winnenden.
Why a sole proprietorship rather than a big agency?
From the first question to handover, you talk to the same person who does the work. Nothing gets passed along, and you know the fixed price before work starts. In return, only a few projects run at the same time, which is why dates are agreed individually.
What's the best way to start?
With the free 15-minute intro call that you book directly online. For a website, the draft follows, before you commit to anything: you see it before you pay. For AI, the AI quick-check is the smallest way in.
Talk briefly,
then decide.
15 minutes are enough to work out whether a website, AI or both make sense for your business right now.
