The smartest thing a VC ever said to me was, "I am in the business of selling money. I'm a salesman, money is my product, and I'm trying to convince you to buy it from me by telling you how my money is better than everyone else's".
VCs have to prove their value to startups, because good ones have choices. A podcast is a great marketing opportunity.
If you have a good track record of execution and have enough experience in your domain, you should be able to raise money (it's a slog but it is doable).
As such, we need to convince promising founders to come to us, convince prospects to become LPs in our funds, and convince other VCs to buy into our investment thesis (and thus build the pipeline to fund additional rounds)
Every job is basically a mix of sales, marketing, and domain experience.
P.S. love lambda ;)
