The best marketing
Even today, it’s still the word of mouth. How clients, partners, competitors, providers, and employees talk about your products and services is far more effective than anything you could say. Whenever you do a pitch, people will argue that you are selling, but if it’s one of your clients that explain how you helped them solve a problem, the credibility of what they say is significantly higher than yours. And their competitors will listen carefully to them. Hopefully they’ll contact you. Or one of your competitors. But that’s life.
