Heap

Heap pioneered the concept of "autocapture" - automatically recording every click, swipe, pageview, and form submission without any manual instrumentation. This means you never lose data because you forgot to track something. The platform allows you to retroactively define events and analyze historical data, making it incredibly flexible for fast-moving product teams. You can answer questions about user behavior instantly, without waiting for developers to implement tracking. Heap is now part of Contentsquare (same company as Hotjar), combining quantitative autocapture with qualitative behavioral insights.
