Yes, someone will notice your product. That someone, by necessity, is someone who knows of your product. So you need to expose people to your product. And ideally, you want this someone to be someone who knows a lot of other people. (A "multiplier". Or "influencer". Or whatever it's called this week)

As an engineer, you might be tempted to call those people "bullshitters", because they talk more than they create. They're not - they have different strengths than you do, that is all. And when you need somebody to talk, you want those people.

And so, knowing them is a good plan. As is, in general, building a network of people you can contact for advice on things you're not good at. This is not about going there and talking. This is about going there and finding people who can complement your strengths. This is about getting feedback on your product. This is about hearing new ideas.

All of that will benefit your product.
