The operating system for folks who build software.We started with open-source product analytics, <a target="_blank" href="https://posthog.com/handbook/story">launched out of Y Combinators W20 cohort</a>. Weve since shipped <a target="_blank" href="https://posthog.com/products">more than a dozen products</a>, including:<ul><li><a target="_blank" href="https://posthog.com/docs/data-warehouse">A built-in data warehouse</a>, so users can query product and customer data together using custom SQL insights.</li><li><a target="_blank" href="https://posthog.com/docs/cdp">A customer data platform</a>, so they can send their data wherever they need with ease.</li><li><a target="_blank" href="https://posthog.com/max">Max AI</a>, an AI-powered analyst that answers product questions, helps users find useful session recordings, and writes custom SQL queries.</li></ul>Next on the roadmap are CRM, messaging, revenue analytics, and support products. When we say every product that companies need to run their business, we really mean it!We are:<ol><li>Product-led. More than 100,000 companies have installed PostHog, mostly driven by word-of-mouth. We have intensely strong product-market fit.</li><li><a target="_blank" href="https://paulgraham.com/aord.html">Default alive</a>. Revenue is growing 10% MoM on average, and were very efficient. We raise money to push ambition and grow faster, not to keep the lights on.</li><li>Well-funded. Weve raised more than $100m from some of the worlds top <a target="_blank" href="https://posthog.com/handbook/strategy/investors">investors</a>. Were set up for a long, ambitious journey.</li></ol>Were focused on building an awesome product for end users, hiring exceptional teammates, shipping fast, and <a target="_blank" href="https://posthog.com/deskhog">being as weird as possible</a>.<h2>Things we care about</h2><ul><li>Transparency: Everyone can read about our roadmap, how we pay (or even let go of) people, our strategy, and how we work, in our <a target="_blank" href="https://posthog.com/handbook">public company handbook</a>. Internally, we share revenue, notes and slides from board meetings, and fundraising plans, so everyone has the context they need to make good decisions.</li><li>Autonomy: We don’t tell anyone what to do. Everyone chooses what to work on next based on whats going to have the biggest impact on our customers, and what they find interesting and motivating to work on. <a target="_blank" href="https://posthog.com/handbook/wide-company">Engineers lead product teams</a> and <a target="_blank" href="https://posthog.com/handbook/which-products">make product decisions</a>. Teams are flexible and easy to change when needed.</li><li>Shipping fast: <a target="_blank" href="https://posthog.com/handbook/values#why-not-now">Why not now?</a> We want to build a lot of products; we cant do that shipping at a normal pace. Weve built the company around small teams – autonomous, highly-efficient groups of <a target="_blank" href="https://posthog.com/founders/cracked-manifesto">cracked engineers</a> who can outship much larger companies because they own their products end-to-end.</li><li>Time for building: Nothing gets shipped in a meeting. Were a natively remote company. We default to async communication – PRs &gt; Issues &gt; Slack. Tuesdays and Thursdays are <a target="_blank" href="https://posthog.com/handbook/company/culture#were-on-the-makers-schedule">meeting-free days</a>, and we prioritize heads down building time over perfect coordination. This will be the most productive job youve ever had.</li><li>Ambition: We want to solve big problems. We strongly believe that aiming for the best possible upside, and sometimes missing, is better than never trying. Were optimistic about whats possible and our ability to get there.</li><li>Being weird: Weird means redesigning an already world-class website for the 5th time. It means shipping literally every product that relates to customer data. It means building an <a target="_blank" href="https://posthog.com/deskhog">objectively unnecessary developer toy</a> with dubious shareholder value. Doing weird stuff is a competitive advantage. And its fun.</li></ul><h2>Who we’re looking for</h2>The ClickHouse Operations team is responsible for the ClickHouse cluster that all other teams (and all customers) use to store and query data.
