Kaltura

Kaltura helps organizations turn content, knowledge, and audience signals into personalized, AI-powered experiences that move people forward. Our platform brings together content, video, data, intelligence, and agentic AI to help businesses engage customers, enable employees, and guide every user with the right content, interaction, or next step in the moment. Kaltura’s solutions are built around two critical business challenges: accelerating revenue across the customer journey and helping people learn, perform, and succeed at scale. **Agentic Revenue Engagement** Kaltura Agentic Revenue Engagement helps organizations create connected, personalized experiences across the buyer and customer journey. Instead of leaving people to navigate static websites, disconnected content, forms, webinars, and follow-up on their own, Kaltura turns these touchpoints into interactive experiences that understand intent and actively guide each user forward. Organizations can create digital destinations, events, webinars, content experiences, and AI-powered conversational interactions that adapt to each buyer or customer. Agentic experiences can answer questions, recommend relevant content, help users explore solutions, capture intent, identify meaningful engagement signals, and connect people with sales or customer teams when human involvement adds value. For marketing and revenue teams, this creates a more continuous journey from first engagement through purchase, onboarding, adoption, and expansion, while providing richer insight into what each account and individual actually cares about. Teams can use Kaltura to: • Create personalized digital experiences for buyers and customers • Run webinars, virtual events, and always-on content destinations • Turn video and other content into interactive, discoverable experiences • Deploy AI-powered agents that answer questions and guide users in real time • Recommend content and next steps based on user needs and behavior • Capture and activate engagement and intent signals • Support customer onboarding, education, activation, and ongoing engagement • Connect digital interactions with revenue workflows and business outcomes The goal is simple: reduce friction across the journey and help every interaction create momentum toward the next meaningful action. **Agentic Learning & Enablement** Kaltura Agentic Learning & Enablement helps organizations turn institutional knowledge into personalized learning, practice, and on-demand guidance that improves performance. Traditional learning often depends on static courses, fragmented knowledge, and one-size-fits-all training. Kaltura creates a more continuous model of enablement, where employees, sales teams, customers, and partners can access the knowledge, practice, and guidance they need at the moment they need it. Organizations can create and manage learning content at scale, transform existing knowledge and video into new learning experiences, personalize learning based on individual needs, and give users AI-powered guides that help them find answers and apply knowledge in their day-to-day work. Kaltura also supports interactive practice and simulation, allowing people to rehearse important conversations and scenarios and receive immediate feedback. This can include sales conversations, customer interactions, leadership scenarios, onboarding, certification, and other high-stakes situations where practice directly affects performance. Teams can use Kaltura to: • Create and manage video, learning, and enablement content at scale • Generate and repurpose content using AI-powered creation tools • Deliver personalized onboarding, upskilling, and continuous learning • Give employees on-demand access to company knowledge and guidance • Provide sales teams with training, coaching, and in-the-moment enablement • Run realistic roleplay and simulation experiences with AI-powered feedback and assessment • Educate and enable customers and partners • Support structured learning paths, certifications, and skills development • Understand engagement, readiness, and learning effectiveness • Connect learning and enablement programs more closely to business performance Rather than treating learning as an occasional activity, Kaltura helps make knowledge and guidance available continuously, embedded into the way people work and perform. **One platform for intelligent digital experiences** Both solutions are powered by the same Kaltura foundation. Kaltura has spent years helping global organizations create, manage, distribute, and understand video and digital content at enterprise scale. Today, those capabilities are combined with AI, audience intelligence, content generation, conversational agents, analytics, and experience orchestration. This means organizations do not have to treat content, engagement, learning, and AI as separate layers. Kaltura can help teams turn existing content and organizational knowledge into active, reusable intelligence; understand what each user needs based on context and behavior; and deliver a personalized experience that responds in real time. The result is a new type of digital experience: one that does more than present information. It understands, interacts, guides, and helps each person take the next step. Whether that next step is booking a meeting, exploring a solution, completing onboarding, learning a new skill, practicing an important conversation, adopting a product, or finding the right answer, Kaltura helps organizations make every interaction more relevant, useful, and measurable. Kaltura is used by organizations around the world to power digital experiences across marketing, sales, customer engagement, learning, employee enablement, education, media, and communications.
