mySecond Information

The PM Operating System for product teams — built on Claude. Your PMs use AI. Without infrastructure, it's just chat. mySecond loads your company context once, builds frameworks into 70+ PM skills, and runs them across the full product lifecycle — discovery, strategy, specs, launch, and operations. Roll it out across the team so every PM works against the same context, the same standards, and the same playbook. One PM team, performing like five. It runs in two places: Claude Code, where PMs draft and ship — and mySecond Companion at mysecond.ai, where context lives, agents run, and Heads of Product oversee the rollout. Three ways to start: → Solo PM OS — $39/mo. For the PM running their function alone. → Team PM OS —Join the early access waitlist. Roll the full OS out across your team. → Custom PM OS — we build and run it with you. Start free at mysecond.ai
