You don't need to start with a $1M+ Super Bowl Ad. Find 10 people, call them, learn what they need, educate them about your offer, take their feedback back to your product. The earlier you can start that process the better, without exception.
I'm not sure 'call 10 people' is the up-thread intended marketing push though? Maybe it is, but certainly not the way I read it (and hence framed my response).
It's a start. You start with 10 calls. You learn from them and build an email to send to 100 people. You book more calls and then take the feedback and put it into a social media post and get 1000 more. Then you take what you learn there and turn it into an ad to show to 10K sets of eyeballs. The up-thread focus is on starting this process early.
