Alleria AI, Inc. builds AI products and infrastructure that help businesses turn communication into actionable business intelligence. Our product ecosystem includes PriorityEngine, an inbox intelligence platform for businesses, and BSOS, an OEM Business Communication Intelligence API designed for software platforms, AI agents and business workflows. BSOS transforms email, messages, tickets, forms, documents and other business communication into structured intelligence including business signals, understanding, context, classification, business facts, business impact, attention, priority, recommended action and explainability. We also operate the Alleria Partner Channel, an invitation-only commercial ecosystem for technology consultancies, agencies, integrators, implementation partners and other B2B technology organizations that want to introduce PriorityEngine or integrate BSOS into relevant customer solutions.

Callab AI builds AI voice and text agents for enterprise contact centers. We help companies automate customer conversations while keeping the telephony, CRM systems, and workflows they already rely on. Many contact centers run on established on-premises phone systems. Bringing AI to those environments is an infrastructure challenge as much as a modeling challenge. Our SIP-native telephony stack connects directly to systems such as Cisco CUCM, Avaya, and Mitel, so customers can deploy AI agents without replacing their phone infrastructure. Our platform lets teams build agents around their knowledge and business rules, connect them to tools that complete customer tasks, and supervise conversations in real time. When a conversation needs human judgment, a team member can take over with the context preserved. Use cases include customer support, call routing, appointment scheduling, lead qualification, and outbound campaigns. Backed by Y Combinator, We serve customers across three continents and are expanding in the US. Our work spans enterprise software, AI, and the telecom infrastructure that makes reliable customer service possible. We're building the next generation of contact-center automation. Explore our open roles to help bring it to more businesses.
