FullStory was founded in 2014 by Scott Voigt, Bruce Johnson, and Joel Webber — the last two being co-creators of Google Web Toolkit (GWT). The company has raised over $200 million in funding and has grown into a major player in the digital experience analytics space.
The platform’s foundation is session replay. FullStory records user sessions by capturing DOM changes (not video), creating pixel-perfect reconstructions of exactly what users see and do. You can watch a user struggle with a confusing checkout flow, encounter a JavaScript error, or rage-click on an unresponsive element.
FullStory coined the term “rage click” — rapid, frustrated clicking that indicates a user is having a bad experience. The platform automatically detects these frustration signals along with dead clicks (clicking on non-interactive elements) and error clicks (clicks that trigger JavaScript errors).
Beyond session replay, FullStory provides quantitative analytics including conversion funnels, user journeys, heatmaps, and scroll maps. The combination of quantitative data (“30% of users drop off at step 3”) with qualitative context (watching those users struggle) gives product teams a complete picture.
Data capture works through a JavaScript snippet that instruments the page automatically, similar to Heap’s approach. Events are captured retroactively, so you can define and analyze interactions after the fact without needing to plan instrumentation in advance.
FullStory’s DX (Data Export) product lets organizations stream captured interaction data to their data warehouse for custom analysis. This recognizes that many data teams want raw event data in their own infrastructure rather than being limited to FullStory’s built-in analytics.
Privacy controls allow teams to mask sensitive content, exclude specific page elements from capture, and comply with GDPR and CCPA requirements.
