PostHog is the only platform that acts like a co-pilot for you (and your AI agents) to do it all – autonomously. We started with open-source product analytics, launched out of Y Combinator's W20 cohort . We've since shipped more than a dozen products , including: PostHog Code , the only AI devtool that understands your product, not just your codebase. A built-in data warehouse , so users can query product and customer data together using custom SQL insights. PostHog AI , an AI-powered analyst that answers product questions, helps users find useful session recordings, and writes custom SQL queries. We are: Product-led . More than 450,000 organizations have installed PostHog, mostly driven by word-of-mouth. We have intensely strong product-market fit. Default alive . Revenue is growing incredibly quickly, and we're very efficient. We raise money to push ambition and grow faster, not to keep the lights on. Well-funded.

About Ramp Ramp is building the smart infrastructure for finance teams, embedded in the transaction flow of every dollar a business spends. We automate how over $200B in annualized spend flows in and out of 70,000+ companies: authorizing payments, flagging risk, categorizing spend, and closing books. The problems are high-stakes, data-dense, and unforgiving. We hire people with high agency and high urgency. We look for slope over intercept. We care less about where you trained and more about what you’ve built. At Ramp, everyone is a builder who owns problems end to end and makes consequential decisions that shape the outcome.

About the Role Design at Ramp looks very different than it did a year ago: we’re building tools and agents, designing memory, shipping PRs, and rethinking the process every few months as new capabilities unlock. A few things have not changed, the role of design is to distill problems to their essence, obsess over craft and delight where it matters most, know customers deeply and advocate for them, lead with creativity and storytelling, and keep it fun, because a product built with joy always wins. We're looking for a Director of Product Design to lead a team of builders across some of our highest-priority bets. This role is for you if you’re excited by: Leading through craft, setting vision and unlocking customer impact: you will define where a product should go, then jump into the details with the team to unblock, teach, and ship. You raise the bar through product judgment, design craft, and your ability to make everyone around you better. Actually shipping and demonstrating real impact: You'll start by owning a product area and team to build trust
