Can you make great products and have success without focusing on marketing?
Let's look at this with the example of recently released films: Barbie and Oppenheimer.
They came out on the same day, they have the same budget for production, gorgeous well-known actors, but there is one big difference. Directors spent $150 million on the marketing of Barbie, while $145 million was spent on the creation. Oppenheimer did not allocate such a budget for marketing.
The result? Oppenheimer's fees are $600 million, Barbie's fees are twice as much - $ 1.2 billion. So if you're making a great product, do yourself a favor and lay down a budget for promotion so as not to steal your profits. In addition to money, "Barbie" obviously received many other advantages, but that's not about it now.
Marketing is an amazing tool, especially when it is handled by a team of professionals, so if the product is great, then it is strange to neglect it. But is it possible to make a cool product without focusing on marketing? Of course, it is possible, even on the example of the "Oppenheimer" ;)
