Searching for Exist stipend Cofounder: IT, Everyone should feel safe in public spaces. Community driven security App.

Büffel is the only first-level support for people being endangered, when they cannot call the police, by a trusted and qualified community with later on police integration. The personal safety market is fragmented. Nora requires seven clicks under threat. SafeNow and Sirene alert only predefined contacts who may be miles away (Safenow also qualified help in certain areas). Each is a point solution. Büffel is the only end-to-end workflow. From silent alarm to nearby friends and verified helper on scene to structured police dispatch, without a break in the chain. The USP rests on five elements no competitor combines. A trained community of verified helpers nearby; planned police integration replacing the unstructured 110 call with real-time operational data; a reputation score ensuring only trusted responders receive alerts; a reward system sustaining motivation over time, turning civil courage into habit; and domain knowledge from six years of active police service embedded in every design decision. Nine in ten incidents resolve when a neutral third party arrives. Büffel makes that happen in under 2 minutes.
