Maestro Labs

Maestro Labs is a Singapore-based productivity software company that builds AI assistants for the tools people already work in - email, meetings and calendars. Its flagship product, MailMaestro, drafts, summarizes and prioritizes email inside Outlook and Gmail, while TeamsMaestro takes meeting notes in Microsoft Teams and CalMaestro handles scheduling. The company positions itself as the largest independent AI email assistant, competing directly with Microsoft Copilot, and reached that scale partly by acquiring Helsinki-based Flowrite in January 2025.
