Started sending cold-LinkedIn connection requests.

There's a huge difference between a podcast and a monologue and that huge difference is of the guest, so the first thing to do was find guests for the podcast. And where do you find smart, charismatic people - Linkedin.
So I started sending cold-Linkedin connection requests to founders, CEO's, CTO's, CMO's, or anyone who would be a good potential guest for this upcoming business podcast.
Initially, the results were pretty good, the ones who would not accept my connection request if it were not a podcast text, started accepting and I started some conversations with the top startup veterans of India.
