Leadbay

Leadbay is an AI lead qualification platform that delivers qualified prospects directly into the assistants sales teams already use: Claude, ChatGPT and Copilot. It specializes in markets where data and buying signals are scarce, such as construction, hospitality, professional services, manufacturing and healthcare, and it searches, reasons and extrapolates to find and rank accounts the way an experienced sales rep would. It is built for B2B sales and growth teams selling into those hard to profile markets. Leads arrive already qualified from the moment a user logs in, built from the company's website and its past won and lost deals, and every like, dislike and contact action refines what comes next. Users can upload existing won and lost companies and people, and Leadbay finds lookalikes and fills in missing data. Through its MCP server, the product also ships a library of interface components so teams can build apps, skills and widgets shaped to their own workflows, schedule tasks and share best practices across the team. It integrates with CRM, ERP, data lake and activation tools, and it is GDPR compliant with a dedicated data protection officer. Pricing is published per user per month. Free costs $0 and provides roughly 5 qualified leads per week with people, phone and email included, and needs no credit card. More costs $100 and provides roughly 50 qualified leads per week plus MCP access in Claude and ChatGPT. Much more costs $400 and provides roughly 300 qualified leads per week with MCP access. Large is custom priced for enterprises, and enterprise engagements can include an engineer deployed alongside the customer's team. Leadbay has announced a $4.3 million seed round and a US launch in San Francisco.
