## Working on now

- Leadbay is developing AI that discovers and qualifies business prospects that conventional sales databases miss, especially low-data, low-signal SMBs and other fragmented parts of the real economy.
- The product analyzes a customer’s offering, past won/lost deals, CRM/ERP/CSV data, and public signals to recommend likely future customers; the company describes this as an inference model and, on its current site, as qualified leads for agentic workflows.
- The company’s named customer examples include L’Oréal, Saint-Gobain, Gerflor USA, Corgi, and Nespresso B2B; earlier materials also describe customers targeting construction, hotels/restaurants, startups, and retail.
- As of the latest reviewed materials, Leadbay is operating from San Francisco and France and is pushing further into the U.S. market while continuing to accelerate in France.
- In a May 2026 press interview, he said the seed financing would fund U.S. expansion, French-market acceleration, and hiring engineers and sales directors; the reported plan was to double the team by year-end.
- He has publicly sought B2B sales leaders, experienced growth or exited-business executives, global VC funds, product-design talent, and early sales hires.
