Thanks for the info. I am aware of clarity.fm. I am thinking more a packaged advisor service like a group of advisors (e.g. one marketing, one product, one legal etc) to provide on-going very tactic advisors based on startups' context. Something like YC is offering in their core program but to every startup.
Because I don't want an armchair advisor w/ no skin in the game to give me advice on generic things like marketing, and product. I want someone who's invested in the journey. They'll also have more meaningful advice b/c it means they've done the research into my product/market/competitors.
