Description

Underdog is a private, local AI assistant for Mac that handles email, calendar, and task management entirely on-device, aimed at users who want AI help with day-to-day organization without their email and calendar data leaving their machine to a cloud service. It is aimed at privacy-conscious Mac users who want AI productivity help without a cloud-based assistant reading their inbox and calendar.

Sista AI (operated by Amsterdam-based consultancy Zalt) is a done-for-you AI agent firm that finds where AI pays off, builds self-learning agents into your existing stack (CRM, ERP, helpdesk), and operates them in production across sales, support, marketing, and back-office ops. It's aimed at businesses wanting real deployment rather than stalled pilots, offering fixed-scope engagements from a €7k proof-of-concept pilot to fully-managed monthly operation. Its flagship product, Sistava.com, is an AI Workforce platform that lets non-technical teams 'hire' AI employees for functions like marketing, sales, HR, and support.
