Ask HN: Transition from web developer to Product Manager

I have been working as a full stack web developer for around 7 years and am interested in transitioning to a technical product manager. Is there a specific path I need to take or how should I go about looking for opportunities outside my current company. I cannot do it at my current company as I don't think they are open enough for that transition. I'm not interested in getting an MBA right now. Any suggestions would be appreciated. I'm pretty tech savvy and have a lot of knowledge about the current happenings and pretty up to date on startups and other things tech.
