About PostHog, Inc.
PostHog is a San Francisco-based open-source product analytics platform founded in 2020 by James Hawkins and Tim Glaser via Y Combinator. The platform combines product analytics (funnels, cohorts, retention), session replay, feature flags, A/B testing, and error monitoring into a single self-hostable stack. PostHog is engineering-led and explicitly designed for product engineers who want to understand user behavior without sending data to a third-party SaaS. The self-hosted version can be deployed on AWS, GCP, or Kubernetes for free. PostHog raised $27M in Series B funding from Y Combinator and Andreessen Horowitz and has become one of the fastest-growing open-source SaaS companies, with 50,000+ companies using the platform.

What people say about PostHog
Our synthesis across ~400 G2 reviews and strong engineering community discussion, 2025-2026. No fabricated quotes, this is the consistent pattern across reviews and third-party analyses.
Most praised
- All-in-one stack (analytics + session replay + feature flags + A/B) in one tool eliminates tool sprawl
- Self-hosted option gives full data control with no per-event costs
- Engineering team ships features aggressively; product improves fast
- Data warehouse native queries let you combine product data with Stripe, Salesforce, etc.
Most cited complaints
- Self-hosted version requires DevOps competence to maintain at scale
- UI and UX less polished than Mixpanel or Amplitude
- Some advanced analytics features still in beta or catching up to dedicated tools
What we found testing it
What's great
- MIT-licensed open source core; self-hosting gives complete data sovereignty, no data ever leaves your VPC, which is the deciding factor for strict EU data-residency and air-gapped financial services requirements (for HIPAA, PostHog points you to Cloud under a BAA, not self-hosting)
- Single bill covers product analytics, session replay, feature flags, A/B testing, surveys, and error tracking; for many teams this replaces three separate tool subscriptions
- Usage-based pricing where more than 90% of products run on the free tier; $0.00005/event after 1M events monthly means a product with 5M events/month pays roughly $150
Watch-outs
- Self-hosted version requires a competent DevOps or platform engineer to manage Kafka, ClickHouse, and PostgreSQL infrastructure; this is not a one-click deploy for non-engineers
- Some modules (LLM observability, data warehouse connector) are still maturing relative to Amplitude's depth
- The breadth of features means new users face a wider surface area to learn; Amplitude's opinionated analytics workflow is faster to adopt for pure-analytics use cases
PostHog funding & ownership
| Round | Amount | Date | Lead investor |
|---|---|---|---|
| Seed | $3M | 2020 | Y Combinator |
| Series A | $9M | 2020 | GV (Google Ventures) |
| Series B | $15M | 2021 | Andreessen Horowitz |
Strong for early-stage and mid-market companies. Open-source moat is significant. Engineering-led culture means product quality is high. Financial stability is solid for a Series B company.

PostHog leadership
PostHog pricing
| Plan | Price | Best for |
|---|---|---|
| Free (Cloud) | $0/mo | Up to 1M events/month |
| Paid (Cloud) | Pay-as-you-go | Growing teams, per-product pricing |
| Self-hosted | Free | Teams prioritizing data control and cost |
| Enterprise | Custom | SLAs, SSO, HIPAA, dedicated support |
The catch: PostHog Cloud is free up to 1M events/month. Beyond that, pricing scales by product: analytics events at $0.000045/event, session replays at $0.004/recording. A team using 10M events/month pays roughly $400/month. Self-hosted is always free regardless of volume.

PostHog FAQs
How does PostHog compare to Mixpanel?
PostHog has a free self-hosted option and all-in-one features (analytics + session replay + flags). Mixpanel has a better UX and more mature analytics features. PostHog is the right choice for engineering-led teams; Mixpanel suits product and data analyst-led organizations.
Is PostHog GDPR compliant?
Yes. PostHog's self-hosted option stores all data in your own infrastructure, which gives maximum GDPR control. The cloud version stores data in the EU on EU deployments.
