Leadbay is the AI-driven prospecting assistant that removes the guesswork from B2B sales. Its platform uses proprietary AI models to identify, score, and surface the leads most likely to convert, giving sales teams a sharper pipeline and a shorter path to revenue. Accepted into Y Combinator’s Fall 2025 batch with a $500k investment, Leadbay completed a Delaware Flip to establish its global holding structure and launched Leadbay 2.0 alongside its proprietary model Lucid-see-V1, which improved prediction accuracy by 45%. The company has also secured a Microsoft Marketplace listing, opening co-sell opportunities at enterprise scale. With €500k ARR signed and a team of 10, Leadbay is headquartered in France with its global operations structured from the United States.
