BioSonic is a Stockholm-based AI company that builds the most accurate bat sound analysis platform available. Founded in 2023, our deep learning models are trained on 2.5 million bat calls and 3.5 million noise files, achieving 98.9% F1 accuracy in independent benchmarks. Ecological consultants, government agencies, and conservation researchers across Europe use BioSonic for automatic species identification, behaviour classification, and collaborative review. The platform in the web processes recordings from all major bat detector hardware and delivers species-level results fast, replacing weeks of manual spectrogram analysis.
