Who you are talking to
Sagar Mahra has run his own ARAG agency in Aachen since 2017, with a team of five. He is a tied insurance agent (gebundener Vertreter) under § 34d (7) of the German Trade Regulation Act, the GewO.
That classification has a practical meaning. He works for one insurer, ARAG, and he is not an independent insurance broker (Makler). The upside is that he knows the ARAG terms down to the small print instead of comparing fifty companies on the surface. If another route fits your situation better, he says so.
The office is at Waldstraße 10 in Aachen. Most conversations happen by phone, WhatsApp or video, which works from Berlin or Munich just as well as from Aachen.
