# The Survey Stack: Survox, LimeSurvey, Typeform, PostHog

> A field guide to four tools that mark the evolution of asking people questions. Survox (born as CfMC in 1967) ran the phone banks and CATI polling of the analog era. LimeSurvey brought open-source web surveys to anyone with a server. Typeform made forms feel like a conversation. PostHog put surveys inside the product, triggered by what users actually do. Together they show how feedback moved from the call center to the codebase.

## Achievements

- Survox (as CfMC) is one of the longest-running names in survey software, active since 1967.
- LimeSurvey is widely cited as the world's most popular open-source survey tool, used in 80+ countries with 80+ languages and 28+ question types.
- Typeform turned conversational forms into a category, raising roughly $188M and reaching a reported valuation near $938M.
- PostHog reached $1M ARR with no sales team and reportedly serves a majority of Y Combinator companies.

## Latest updates

- **2026-08** — In-product, behavior-triggered surveys (PostHog-style) are now table stakes for software teams, while phone/CATI (Survox) and open-source web surveys (LimeSurvey) still hold research and enterprise niches.
