What resources are you using to do a deep dive into a sub-industry? IBIS world is great for high level, but I'm trying to go a bit deeper. Example (this isn't my industry, just an example of what im talking about), IBIS world may have 'Health and wellness Spas in the US' as a high level, but what if I wanted to learn about specifically Spa resorts or Franchises only? Is it just a bunch of Google searches and conversations or is there an IBIS alternative that can highlight TAM, growth rates, SWOT, competition etc.

Note, i don't have any public companies that can be used as an example
