Overview

ON24 is a San Francisco-based business-to-business software company that provides cloud applications for webinars, virtual events, digital content experiences, and engagement analytics. Its platform is primarily used by marketing, sales, communications, education, and customer-facing teams that need to deliver online events and turn participant activity into usable business data. The company began in 1998 as NewsDirect Inc., founded by Csaba Fikker, Bill Bales, and Nina Chen. The original concept was an internet-based distribution service for video press releases. After receiving initial investment, the founders and board recruited Sharat Sharan as chief executive. In 1999, the company adopted the ON24 name and shifted toward online financial-news streaming. The collapse of the dot-com economy changed the business materially: ON24 discontinued its news operation in August 2002 and concentrated on webcasting technology instead. That refocusing established the core business model that later became associated with ON24: delivering live and on-demand online presentations while capturing registration, attendance, viewing, question-and-answer, polling, content-download, and other interaction data. The company subsequently broadened its platform beyond individual webcasts. In 2006 it began international expansion, establishing a presence in the United States, the United Kingdom, Australia, Singapore, and Spain. In 2008 it introduced ON24 Virtual Show, extending the product scope to virtual trade shows, conferences, and other multi-session events. ON24 positions its products as an enterprise digital-experience layer rather than merely a video-streaming service. Its applications support branded event environments, audience interaction, content libraries, landing pages, lead capture, analytics, and integrations with marketing-automation and customer-relationship-management systems. The platform uses browser-based delivery and HTTP-based live streaming, allowing organizations to run events without requiring participants to install specialized software. ON24 has described integrations with tools and services including HubSpot, Zapier, Workato, marketing-automation platforms, and CRM systems. The company’s commercial focus is especially relevant to B2B organizations with complex buying journeys. Webinars and virtual events can be used for demand generation, product education, thought leadership, customer training, internal communications, and sales follow-up. Engagement information collected during those activities can be connected to marketing and sales workflows, helping organizations evaluate audience interest and prioritize follow-up. ON24’s content-hub and landing-page capabilities also support the reuse of event recordings and related materials after a live broadcast has ended. ON24 became a publicly traded company in February 2021. Its initial public offering consisted of 9,845,069 shares priced at $50 per share, with gross proceeds of approximately $492.3 million before offering expenses. In 2023 and early 2024, the company expanded its product strategy with generative-artificial-intelligence capabilities associated with its Analytics and Content Engine, or ACE. These capabilities were intended to help customers analyze engagement and derive or activate content from their digital experiences. ON24 continues to operate internationally, with offices and affiliates across North America, Europe, and the Asia-Pacific region. Its present identity combines webinar and virtual-event infrastructure with content management, engagement measurement, marketing technology integrations, and increasingly AI-assisted analytics and content services.

History

ON24 was established in 1998 as NewsDirect Inc. by Csaba Fikker, Bill Bales, and Nina Chen. The original business was conceived as a distribution center for internet-based video press releases. Following an initial investment, the founders and board recruited Sharat Sharan as chief executive officer. Under Sharan’s leadership, the company changed its name to ON24 in 1999 and pursued a business focused on streaming online financial news. The dot-com bust forced a substantial change in direction. Rather than continuing as an online financial-news operation, ON24 concentrated on the underlying webcasting technology and the delivery of live online presentations. The company discontinued its news operation in August 2002. This transition formed the basis for its later identity as a provider of business webinar and virtual-event infrastructure. ON24 began international expansion in 2006, developing operations or affiliations in the United States, the United Kingdom, Australia, Singapore, and Spain. The company broadened the use cases for its platform in 2008 with the launch of ON24 Virtual Show. The product supported virtual trade shows, conferences, and related event formats, moving ON24 beyond single-session webcasts and toward larger, multi-participant digital experiences. Over time, ON24 added capabilities for audience interaction, event registration, polling, questions, content distribution, analytics, landing pages, and post-event content reuse. Its platform also developed integrations with marketing-automation and customer-relationship-management systems. These features aligned the company with B2B demand generation and revenue-marketing workflows, where webinar attendance and content engagement can inform lead qualification and sales follow-up. ON24 completed an initial public offering in February 2021. The offering comprised 9,845,069 shares of common stock priced at $50 per share and generated approximately $492.3 million in gross proceeds. The listing marked a significant corporate milestone after more than two decades as a private technology company. Beginning in 2023 and continuing into January 2024, ON24 expanded its platform with generative-AI services associated with the Analytics and Content Engine, known as ACE. The initiative reflected the company’s effort to combine event and content engagement data with automated analysis and content-related workflows. ON24 currently describes itself as a cloud platform serving webinars, virtual conferences, content hubs, landing pages, engagement measurement, and related digital experiences. It maintains a presence across North America, Europe, and the Asia-Pacific region, with operations in the United States and affiliates in the United Kingdom, Australia, Singapore, and Japan.
