PostHog joins YC W20 batch
PostHog was founded by James and Tim on January 23rd, 2020. We got into Y Combinator's W20 batch, moved to San Francisco, and just a couple of weeks after starting realized that we needed to build PostHog!
SDKs for web and mobile
| Web (frontend) | Server-side libraries | Mobile libraries |
|---|---|---|
| Use autocapture to collect client-side events without any special instrumentation. | Capture server-side events - best used in conjunction with a frontend web library | Send custom events and identify users. Record mobile sessions and use feature flags. |
| JavaScript | Node.js | Android |
| React | Python | iOS |
| Next.js | Java | React Native |

Warning
You'll hate PostHog if...
| You enjoy "jumping on a quick call" with sales | Sorry, we don't force you to talk to anyone. But you can watch a recorded demo (at your own pace) or request a personalized demo if you like. |
| You love needlessly wasting company money | We only have usage-based pricing that decreases exponentially with scale. |
| You'd rather buy before you try | We offer a free tier so large that only a fraction of our customers pay us anything. Even worse, we continually try to reduce our pricing. |
| You think your email is a good trade for that free whitepaper | Please press Ctrl + W now, or ask your network administrator to close your window. |
| You give out your credit card details to strangers | You'd rather buy a product you've never used instead of a generous free trial? |
| You're desperate for commitment | Sadly, we don't offer annual contracts (unless you ask for one). |
| You loathe new features, and bug fixes | Unfortunately we release new updates weekly. |
| You'd rather buy disparate tools and mangle them together | Apologies. Our focus is for you to engineer your product, not your data. |
| You like buying a whole product suite to get access to one tool | Alas we don't force people to buy stuff they don't use. We suit people who want to pay by product. |
| You think CSMs are your friends | Honey, those emails are automated. |
| You enjoy sitting through hours of training more than using the product | No training is required to use PostHog, though we have plenty of docs and guides if you need some guidance. |
| Data privacy isn't a big deal to you. (GDP-what now?) | Get cookie-less tracking, regional hosting, and raw database access. |
| Networking events are your things | We put on an event once. It was a disaster. Never again. |
| You love being out of the loop | We publish our roadmap, strategy, and company handbook. |
| Your CRM is a Rolodex | We don't even use phones, though we do have a fax number for legal and compliance reasons. |
API
We built PostHog on our API. This means you get full access to anything you want with your event and customer data that's ingested by PostHog. Here are some examples.:
| feature_flags | insights | insights | persons |
|---|---|---|---|
| Evaluate feature flags from anywhere | Pull basic site stats from saved insights | User-facing analytics | Read/write user properties and display in your app |
| If you don't use one of our SDKs, you can get a flag status for a user from the API on-the-fly. | Show stats like active users, pageviews, or number of daily signups (like we use near the bottom of this page!). | Build your own visualizations of insights within your own app or internal dashboard. | Use PostHog as an external database by storing/reading user data and showing it in their user profile. |
| cohorts | annotations |
|---|---|
| Add high-value users to a cohort | Notate when a feature is released |
| If you're running Clearbit on new signups, you can automatically add them to a cohort based on criteria from enrichment services. | Annotations are useful for understanding inflection points in insights. You can programmatically create annotations like when a PR is merged. |
Explore the API
SQL access included
PostHog provides complete SQL access to your data. Use SQL expressions to use JOINs and subqueries, filter event lists, and write complex queries (that aren't supported by the PostHog UI) to analyze data in any way you want.
For example...
| Double (or even triple?) breakdowns |
| concat(properties.name,' ; ',properties.$current_url) |
| Advanced date filtering, relative times, weekly/monthly reports |
| Custom SQL insights directly accessing data |
| Custom scoring or "group/bin" events |
| NPS score, superhuman score calculations |
| Access JSON, object, list data |
