The amount of people who pay others over the phone for advice around the world.
- Lawyers
- Consultants
- Coaches
- Advisors
- etc.

So it's VERY big.

How big are the market size of others in the same space (Maven, Keen, etc)? Keep in mind also that there are other "free" places for getting professional (if not always reliable) advice--linkedin, quora, answers, etc.

How much is TAM important/relevant to Clarity? What is your reasonably reachable market size, and how quickly can you dominate in that market? Just a thought to ponder...

In my opinion the TAM for Clarity if almost quasi-infinite plus or minus a few hundred people and the number is growing daily. Everybody needs advice on one subject or another at any given moment in time. The questions and answers that you get through Clarity are unparalleled and unequaled at this time.

And the calls that I have received have been such that I would not have given advice for free.
