Conversational AI (CAI) and AI agents are transforming enterprise-customer engagement, evolving from scripted chatbots to intelligent, autonomous systems capable of real-time, human-like interaction. This shift is driven by rapid advances in voice AI, multimodal interfaces, and large language models that enable contextual understanding and dynamic task execution. As these technologies scale, enterprises are embedding AI across a wider range of customer-facing functions – from handling service requests to automating complex tasks such as refunds and appointment scheduling. This compendium provides comprehensive and fact-based snapshots of 22 CAI and AI agent technology providers and offers insightful analysis of their capabilities. The compendium enables providers to benchmark their capabilities against their peers, while buyers can assess the providers based on their desired set of capabilities.

Enterprises are increasingly adopting cloud-based communication platforms to integrate messaging, voice, video, and other interaction channels into business processes without heavy infrastructure investments. Communication Platform-as-a-Service (CPaaS) solutions enable scalable, programmable communication capabilities through APIs, SDKs, and low-code frameworks, thus supporting diverse use cases across marketing, customer service, and operations. As the market matures, providers are transitioning from core communication enablement to comprehensive, AI-powered engagement platforms that combine analytics, orchestration, and automation. Emerging differentiators include conversational AI, sentiment analysis, generative AI-driven bots, and integration with enterprise systems such as CRM and ITSM platforms. This compendium profiles nine leading CPaaS providers, detailing their capabilities, offerings, commercial models, and partnerships. The analysis draws on Everest Group’s annual RFI process (CY2025), provider briefings, and client references. Stakeholders can use this report to compare provider maturity, compare innovation roadmaps, and guide partner selection for communication modernization initiatives.

Enterprises are moving from point solutions to scalable cloud contact centers to improve resilience, speed, and customer outcomes. Contact Center-as-a-Service (CCaaS) platforms deliver core capabilities for omnichannel interaction management, including Automatic Call Distribution (ACD), IVR and self-service, workforce optimization with forecasting and scheduling, and analytics for performance and quality. Providers address diverse regulatory, localization, and integration needs across geographies and industries. As AI integration accelerates, providers are evolving from basic cloud contact center tooling to end-to-end experience platforms powered by agent assist and autonomous agents. This compendium profiles 19 providers, detailing their capabilities, offerings, commercial models, and partnerships. The analysis is supported by Everest Group’s annual RFI process (CY2024-25), provider interactions, and client references. Stakeholders can use the analysis to align provider shortlists with operating models, compliance needs, and transformation roadmaps.

Conversational Artificial Intelligence (AI) is a network of advanced technologies and solutions that communicate with each other to share information across systems in a contact center environment. Since the pandemic, the use of conversational AI solutions has grown significantly worldwide. Enterprises are increasingly adopting these solutions to provide superior customer experience, drive customer acquisition, and create market differentiation. Technology advances and themes such as omnichannel deployment, agent-assist, multi-language support, tracking of customer journeys, enhanced AI capabilities, demand for self-serve solutions, and personalized customer experience are further driving their adoption. Conversational AI providers can tap into this opportunity by improving product capabilities to drive wide-scale conversational AI adoption. With the growing impact of conversational AI platforms, it is vital for enterprises to choose solutions that meet their current business requirements and accommodate future needs.
