We are Steven Siebert and Lars Weidner. We founded Siewei in Frankfurt so that businesses stay reachable, even when the team has no hand free.
Two rings decide whether somebody becomes a customer or moves on. People who cannot get through rarely try twice — they take the next name on the list. For the business, that is a lost order. For the caller, a poor first impression.
We built Siewei for exactly these moments: a digital receptionist that picks up, understands the request and books the appointment. It is not meant to replace the front desk team, but to take the calls nobody there has time for right now.
How Siewei works →
This is where Siewei was founded and where we are based. In the Frankfurt area, we are happy to visit you on site.
At Siewei there is no call centre and no waiting line. When you talk to us, you talk to the two people who built the product and stand behind it.
Steven is your first point of contact. He shows you Siewei in the demo, agrees the greeting, opening hours and typical requests with you, and stays available after launch whenever you want to change something.
Lars built the technology behind Siewei and runs it: the server in a data centre in Nuremberg, the phone connection, the speech processing and the encrypted storage. He makes sure that as little as possible is stored.
These four principles are built into the assistant, not written into the small print.
Every conversation starts with a notice that a digital assistant is on the line. Anyone who would rather not is put through, or leaves a callback request.
If a request sounds like an emergency, the assistant stops booking and immediately refers the caller to 112 or the relevant out-of-hours service. It makes no diagnoses and never gives the all-clear.
Our server is located in Germany. Of the conversation itself, we keep neither audio nor a transcript there, only an encrypted summary for you. The basis is a data processing agreement under Art. 28 GDPR.
The assistant follows the rules you set: which appointments it offers, when it answers and when it transfers a call. What happens next with a request is always up to your team.
“When nobody answers the phone at a business, it is almost never the team’s fault. It is because nobody can be in two places at once.”Steven Siebert and Lars Weidner, founders of Siewei
