Let the best products win
There is a fundamental shift in what "sales" and "marketing" implies in this new digital world. We are starting to see the best products surfacing to fame without involving any traditional marketing/sales and that too with very limited budgets. The distance between good products to its customers is being reduced. The budgets will shift in building better products than marketing. If you look at how discovery-led commerce is happening (e.g. Wanelo, Pinterest, etc.) OR how enterprises are discovering products (e.g. cloud-based products), there is no way to build a great business without building a great product.
