Introspace

Introspace matches rooms in Berlin through people you already know. No cold messages, no strangers. A match only happens when a mutual contact knows both sides — someone who can vouch for the connection and make the introduction. HOW IT WORKS - Post a room you're offering, or describe what you're looking for - Share your listing with friends — on social media, in group chats, anywhere - Friends who save it become your connectors, and their saves build your network - When someone has saved both a room and a seeker, it's a match - That person — the connector — makes the introduction PRIVACY BY DESIGN Photos and identities stay hidden until both sides agree to be introduced. Until then, your mutual contact appears only as a shared connection. BUILT FOR BERLIN District-aware matching with budgets and move-in dates — rooms, sublets, and flatshares across the city. Free. No ads.
