Deepslate is a European speech-to-speech voice AI model lab building ultra-fast, GDPR-compliant AI voice agents designed specifically for European enterprises, supporting 27+ languages with sub-250ms end-to-end latency. Unlike multi-component pipelines, Deepslate's native speech-to-speech model processes voice input and generates voice output directly without separate STT, LLM, or TTS components. The company targets regulated verticals such as banking, insurance, retail, and healthcare, and is both GDPR-compliant and ISO 27001 certified with EU cloud or self-hosting options. Deepslate raised a pre-seed round led by SIVentures, with Fadelia Invest also noted as an investor, and was originally incorporated as Rooms Technology GmbH before rebranding to DeepSlate in early 2026.
