Sleak AI is an AI-powered people development platform that builds professional skills through conversation. Instead of delivering static training content, Sleak's AI Coach teaches through personalized dialogue, trains through realistic simulated scenarios with virtual counterparts, evaluates performance against defined standards of excellence, and adapts to each individual's pace and needs. Managers define what their team needs to achieve, learning about a new product, improving sales conversations, sharpening leadership skills - and Sleak's AI Coach develops the specific knowledge and conversational competencies required. The Coach is voice-native, always available, and endlessly patient. Sleak is purpose-built for enterprise people development. It is not an LMS with AI bolted on, nor a generic chatbot. It rethinks how organizations develop their people: initiative-based execution replaces course catalogs, scorecard-driven evaluation replaces completion tracking, and simulated practice replaces passive content consumption. Founded in 2024 and headquartered in Munich, Germany, Sleak serves enterprise teams across the DACH region and beyond.
