Ask questions about how people use your product

Literally every piece of SaaS that a product engineer needs. This includes tools for building products, talking to customers, and making sense of all your customer data. PostHog is a single platform for people who build things. PostHog was hatched in Y Combinator's W20 batch. We launched on Hacker News with our MVP in 2020 – just 4 weeks after we started writing code. The response was overwhelmingly positive. But our approach to building PostHog is very different. We're building the company we've always wanted to work for. This means rejecting all the annoying parts of the SaaS industry that have somehow become industry-standard. If it gives you the ick, you know it gives us the ick too. You can sum it up our ideology with this: we try to treat you how we'd want to be treated. While Salesforce hikes prices 6% annually, PostHog proves there's room for startups that do the exact opposite of what private equity-backed software companies typically do. The TLDR newsletter highlighted an article that covered some of the key things that make us different. Here are a few more they missed: The reason we uniquely love doing all these sorts of things is that we grow because of our reputation on the internet, whereas every single competitor grows by salespeople. This aligns us with customers. Long term, that is what wins. You can see how our entire company operates. You won't get this level of transparency from most companies! Sure, building one product is great, but why stop there? We're going to build every piece of SaaS you need to make your product successful. You read that right. We've already got the world's best track record at delivering them by being the widest with so many customers. Companies with large sales teams use value-based pricing where they try to suss out how much you're willing to spend. PostHog operates more like a utility – we cover our costs with razor thin margins, and we make up for it with scale. PostHog is always cheaper than the cheapest major competitor, so you know you don't have to compare pricing for each new product. And because every product has a generous free tier, you can always try it out before paying anything at all. Without talking to sales. Because our pricing is completely transparent. The team at a recent offsite in Tulum Nobody wants to be a sheep, but it's probably a good sign when something is very popular. Whether you're looking to bring PostHog into your business – or if you're looking to build products with us – we hope you leave our portal on the internet with the understanding that we're here to build a generational company. This isn't a bait-and-switch scheme or an attempt to exit in a few years. We're building the company we've always wanted to work for – and the type of organization that we'd want to buy software from. If we haven't convinced you yet, come back to our site in a few
