Description

Callio is an AI app that calls US businesses on a user's behalf (sourced via Google Maps) to handle tasks like checking hours, availability, or pricing, so the user doesn't have to make the phone call themselves. It is aimed at individuals who want a specific piece of information from a local business but want to avoid making (or waiting on hold for) the phone call personally.

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.
