Are you a multimillionaire or it just happened to you that it would be a good idea to target them?

Yes, Google has been good to me.

There is a wedge of people that have enough money that they want to manage it themselves; but not so much that's it's overwhelming. Getting into 25M+ is multi-family office level I believe.

Also, the prosumer market should have better margins than general consumers (less price sensitive).

More seriously, paying clients are a good thing and selecting for those that afford something is not unreasonable (although glove makers and cobblers for the Georgian and Victorian era wealthy often went broke as the upper class often refused to pay).

Don't discount familiarity with the finances of millionaires by other mean, when I worked in mineral and energy intelligence the bulk of our clients were wealthy enough to discount all IPO's below 50 million as "small beer".
