Propane

We've all been in that meeting. The one where everyone has a different take on what to build next. Someone quotes a customer call from last month. Someone else pulls up a support ticket. A third person has a Notion doc nobody else has read. Nothing connects. The decision gets made on gut feel — and you leave the room slightly unsure you got it right. Dennis lived that as a CPO for years. The context never made it to the room. Customer evidence scattered across six tools. Feedback from a €500 account carrying the same weight as a €50k one. Insights from last quarter's research buried before anyone shipped anything. He built Propane because that problem felt embarrassingly solvable — and nobody had solved it. The idea is simple: PMs deserve the same AI-native environment that engineers got with Cursor. A workspace where customer signals, company context, and agents that actually know your product work together — so you spend your time deciding, not searching. Propane connects your stack and builds from there. Signals from real customers, weighted by revenue. A shared surface to reason, write specs, and align the team. Agents that remember what your customers told you last quarter and help you act on it. We're a small team in Vesterbro, Copenhagen — a few minutes from the central station. Flat, direct, and low on process. Everyone owns something real. We hire makers — people who'd rather figure something out than wait to be told how, and who find genuine satisfaction in shipping something that didn't exist last week. Previous founders tend to feel at home here pretty quickly. Pre-seed, backed by people who've built and scaled companies like Lovable, ElevenLabs, Pleo, GameAnalytics, and Neurons. Early days — which means what you build now shapes what this becomes. If you want to shape what it means to be a PM in the age of AI — and you'd rather have real ownership over that than a comfortable title at a bigger company — we'd love to hear from you.
