Your best business partner for YOUR B2BC GTM strategy is Meta.

How can I make such a blanket statement?

Because Meta is the best business partner for almost EVERY business.

You pay them a few bucks, and they will put your app in front of people who care.

Sounds like B2C? Because it is.

People often think B2B2C is easier because "incumbents" already have the users.
The truth is, B2B2C is often a nightmare. Incumbents demand features that don't make your user experience better (in fact, they always make your UX worse), take ages to convince, and often result in much lower conversion than you'd hope.

Go get your own users - stop relying on other people.

They are not your customers - they are your competitors. Disrupt them.
