Wildix

x-bees by Wildix is a unified communications and contact center platform with built-in AI that helps sales and customer support teams manage conversations across voice, video, chat, meetings, WhatsApp, SMS and other channels, and record those conversations automatically in their CRM. It is built for companies where sales and support teams generate the majority of new revenue, typically between 50 and 1,000 employees. x-bees combines three functions usually bought separately: a business phone system, a contact center with routing and supervision, and conversation intelligence that analyses and scores interactions and sends prompts and alerts to agents and managers. The platform integrates natively with Salesforce: conversations populate the CRM automatically, and the relevant Salesforce information appears inside x-bees the moment a rep needs it, before, during or after a call. Other CRMs are supported through standard integrations. Key capabilities: - Wilma AI agents that answer, qualify and book meetings around the clock, create CRM records, and log a full transcript and decision trace for every conversation. - Revenue Intelligence that scores 100% of interactions, human and AI, on the same metrics, with dashboards configured in plain language. - Wilma AI assistant that briefs users before and during calls and answers questions across the whole conversation archive, with links to the source. - Mobile and eSIM support, so calls made from a smartphone are captured and logged like any other channel. - Single-tenant deployment, GDPR, HIPAA and SOC 2 compliance. x-bees is sold and implemented exclusively through certified Wildix partners.
