Leadbay is a Y Combinator (F25) B2B sales startup building a domain-specific AI model that discovers and qualifies small-to-mid-sized business leads that traditional platforms like LinkedIn, ZoomInfo, Apollo, and Clay can't find. Trained on market data, a company's own CRM/ERP history, and reps' instincts, Leadbay learns a team's Ideal Customer Profile and predicts who will buy next - delivering qualified leads directly inside agentic workflows and AI apps like Claude, ChatGPT, and Copilot. Customers in data-scarce industries such as construction, hospitality, manufacturing, and B2B services report roughly 3-5x more qualified prospects. The company raised a $4.3M seed round led by Y Combinator in May 2026 and is based in San Francisco.
