We’re working to increase the number of successful products in the world We’re a small (but growing) team building an open source platform that empowers customers to create successful products. Until now, tools for building products have been fragmented. Product analytics, heat maps, session recording and A/B testing all provide immense value, but existing tools weren’t natively built to work together. PostHog is different by offering these tools (and more) in a single platform that you can host yourself. We started PostHog as part of Y Combinator's W20 cohort and had the most successful B2B software launch on HackerNews since 2012 - with a product that was just 4 weeks old. We're proudly backed by some of the world's top investors and believe in product-led growth, where we build something awesome and let our product bring the users, rather than an outbound sales team and regular cold calls. What does this mean for you? We have a lot of capital, but we're a lean, strong team - so you've got the opportunity to have a huge impact.
