About us
Independent advice in a market built on selling.
Dr. Liewehr Consulting GmbH is a provider-neutral telecommunications consultancy for business customers. We don't sell a network — we represent your interests towards the providers.
Our approach
First understand, then compare, then negotiate.
Most companies pay more than necessary for telecommunications — not out of negligence, but because the market is deliberately opaque. We create clarity: we analyse your real needs, compare the whole market and, through our framework agreements, secure terms that remain closed to individual customers.
And we stay on board afterwards: we keep an eye on contracts, deadlines and invoices so the savings don't evaporate after a year.
What we stand for
Four principles that set us apart.
Provider-neutral
Tied to no network operator. We compare Telekom, Vodafone and O2 on equal terms.
Independent
Our recommendation follows your needs — not the commission interest of a provider.
Personal
One fixed point of contact instead of a rotating hotline. You always reach the same person.
Nationwide
Based in Berlin, serving business customers across Germany — on site and remotely.
