Mindstream

An AI assistant for businesses selling products overseas. It helps sales teams research potential buyers, understand email conversations, and prepare their next follow-up.

Independent venture / 2025–present

A connected sales workflow

Buyer research, company news, and customer conversations often live in separate places. Mindstream brings that context together so a seller can move from information to a considered next action.

What I own

As founder and product / AI engineering lead, I work across problem discovery, product direction, implementation, and iteration with merchants. The product spans a web application and a Gmail extension, with accounts, payments, and backend synchronization connected.

01 / Discover the right companies

Buyer Radar starts with a seller’s product link and business context. It creates a Market Brief — a summary of what the seller offers and which buyers to look for — researches potential buyer companies with public-source evidence, and uses merchant feedback to inform subsequent searches.
