Most new products don’t get advertised. That happens later after they’ve made some initial sales. Those initial sales often happen from just placing it on some shelf space, real or virtual, where relevant consumers are liable to find it.

Have you ever built or sold products, worked in a startup? I have worked in several many tried the if we build it they will come strat and it fell flat.

The only companies that have made any real money have had to use Ads from the very start.

You can catch lightining in a bottle but exceptions here prove the rule.

It's absurd to think anyone will care about your product if you don't.
