# Discovery Call with Vishnu Prithiv

> A 30-minute call for businesses that want more qualified sales conversations, whether your customers are in the United States, Canada or another market we serve. We review the customers you want to reach, your territory and how your team follows up, explain how pay-per-lead, pay-per-appointment and pay-per-close work for your market, and agree the next step toward a written quote. If podcast-led growth fits better, we cover that too. Partners: please email contact@vivinsales.ca. Looking for a role at Vivin? Please apply at vivinsales.ca/careers/.
