## Working on now

- Building Leadbay as a provider of qualified leads for AI agents, with use inside Claude and ChatGPT agentic workflows.
- Targeting small and medium-sized businesses with limited digital footprints—businesses traditional prospecting databases often miss.
- Developing inference models that learn from salespeople’s instincts and feedback to identify promising companies from sparse or fragmented data.
- Expanding Leadbay in the United States from San Francisco; the company has described plans for U.S. go-to-market hiring and additional engineering and sales hires.
- Working with customers including L’Oréal, Saint-Gobain, Gerflor USA, Corgi and Nespresso B2B, according to Leadbay’s YC company profile.
- Pursuing research collaboration with Sorbonne University on inference models for information-poor data.
- Developing an MCP-native product and distribution around qualified data for agentic workflows.
