ON24 sells a cloud-based B2B marketing platform built around interactive webinars and virtual events. The core idea is that traditional B2B marketing tools like email and digital ads are one-way and generate little actionable data, while ON24's platform creates two-way digital experiences that capture rich behavioral data on prospects, which customers feed into their CRM and marketing automation systems to prioritize sales outreach. ON24's main products include ON24 Elite (the core webinar product), ON24 Engagement Hub (an always-on content portal), ON24 Target (personalized landing pages), and ON24 ACE (an AI add-on that converts completed webinars into short clips, blog posts, and social content, and provides engagement analytics and buying intent scores). ON24's customers are B2B companies — particularly in technology, financial services, life sciences, and professional services — and ON24 sells to them through a direct sales force. ON24 generates roughly 92% of revenue through software subscriptions and the rest through professional services. The company reports ARR as its primary metric and grows via a land-and-expand model, upselling additional products and expanding into new business units within existing accounts. AI-powered ACE is the primary upsell vehicle, and ON24 is further expanding its AI suite to automate multi-channel content campaigns and localization. ON24 recently partnered with LinkedIn to allow customers to publish events directly on LinkedIn and drive registration from LinkedIn audiences, which management expects to become a meaningful new business driver.
