Conny

Conny (formerly EverEstate) is a Berlin-based legal tech company specialising in two of the most common legal disputes in the German rental market: recovering wrongfully withheld rental deposits and challenging excessive rent increases. The platform has helped tens of thousands of German tenants successfully assert their rights.

For expats leaving a German apartment, the security deposit (Kaution) — typically three months’ net rent — is frequently returned late, reduced without adequate justification, or withheld entirely. German law provides tenants with strong protections, but asserting these rights requires knowledge of the legal framework and willingness to challenge landlords formally. Conny handles this process on behalf of tenants: assessing the legitimacy of deductions, sending legal letters, and escalating to legal proceedings if necessary.

The Mietpreisbremse (rental price brake) service helps tenants in relevant rental markets identify whether their rent exceeds the legally permitted level and recover excess rent paid — potentially representing significant sums over a multi-year tenancy.

Conny operates on a no-win, no-fee basis for most of its services — meaning clients only pay when Conny successfully recovers money on their behalf. For expats leaving Germany or challenging unjust deposit deductions, Conny is one of the most straightforward routes to recovering what they are owed.
