Heap vs ElevenLabs
Side-by-side comparison of AI visibility scores, market position, and capabilities
Auto-capture analytics platform acquired by Contentsquare; retroactive event analysis from automatically collected user interactions competing with Mixpanel and Amplitude for product analytics.
About
Heap is an automated digital analytics platform that captures every user interaction on a web or mobile application — clicks, form submissions, page views, gestures — without requiring manual event tracking instrumentation, enabling product teams to retroactively analyze any user behavior even if they didn't think to track it in advance. Founded in 2013 by Matin Movassate and Ravi Parikh in San Francisco, Heap was acquired by Contentsquare (a digital experience analytics platform) in 2023, integrating Heap's behavioral analytics with Contentsquare's heatmaps and session replay capabilities.\n\nHeap's "capture everything" approach differs fundamentally from event-based analytics tools like Mixpanel and Amplitude — rather than requiring developers to manually instrument specific events (which means any unanticipated behavior is invisible), Heap's JavaScript SDK auto-captures all user interactions at the DOM level. Product managers can then define virtual events retroactively in the UI and instantly see historical data for those events without waiting for new data collection. This retroactive analysis capability is valuable when a product issue is discovered and historical context is needed.\n\nIn 2025, Heap operates within Contentsquare's expanded digital experience analytics platform, combining Heap's behavioral event analytics with Contentsquare's heatmaps, session replay, voice of customer, and AI-powered insight capabilities. Contentsquare (which also acquired Hotjar in 2021) has built a comprehensive digital experience intelligence platform. Heap competes with Mixpanel, Amplitude, and Google Analytics for product analytics market share. The 2025 strategy within Contentsquare focuses on deepening integration between Heap's quantitative behavioral data and Contentsquare's qualitative experience data for a unified digital experience view.
